Eliminating Trachoma in the Most Impoverished Communities

TrachomaTrachoma is an infectious eye disease caused by the bacterium Chlamydia trachomatis. It is a chronic form of conjunctivitis and causes 1.4% of global blindness, yet governments can completely prevent it. Thirty countries across Africa, Asia, Central and South America, the Middle East and Australia have faced trachoma as a public health problem. It affects the most impoverished parts of the world. 

Infection spreads easily due to poor hygiene, crowded housing and limited access to sanitation and water. Viral disease and poverty fuel this spread, making people vulnerable to preventable diseases such as trachoma.

Eliminating Trachoma in Libya

On February 18, 2026, the World Health Organization (WHO) celebrated Libya’s elimination of trachoma. Libya struggled with trachoma for more than a century, but hard work and commitment led to this recent success. The country’s victory over trachoma shows how supporting the fight against neglected tropical diseases can help millions over time.

Political unrest and displacement in Libya limited access to quality health care, yet the country still managed to eliminate trachoma. Displacement and such unrest drive poverty by increasing the demand for water, sanitation and hygiene services. This connection between disease and poverty makes eliminating trachoma even more significant.

The SAFE Initiative

Countries affected by trachoma adopted the Surgery, Antibiotics, Facial cleanliness and Environmental improvement (SAFE) strategy. Through this effort, Pfizer and the International Trachoma Initiative (ITI) have delivered more than one billion doses of Zithromax to countries in need. Experts now estimate that trachoma could be eliminated as a public health threat worldwide by 2030.

ITI, a U.S.-based nonprofit, currently operates in more than 14 countries across Southeast Asia and Africa. These interventions address the link between disease and poverty and have improved the lives of millions. Twenty-seven additional countries, including Papua New Guinea and Pakistan have also eliminated trachoma, underscoring the importance of tracking its prevalence and taking decisive action against infectious diseases. 

Fewer than 100 million people now require treatment, a historic global low since the WHO began recording cases. This milestone reinforces the need to confront disease alongside poverty. It demonstrates how strong local leadership, backed by international coordination, can improve the well-being of the world’s poorest populations.

Final Remarks

The massive success of the trachoma eradication campaign demonstrates the positive impact international help can have on many other tropical diseases. Research into trachoma has taught researchers much about how to slow its spread. Making hygiene a game for young children helps them avoid touching their eyes and mouths, which, in turn, helps women, who often act as primary caregivers. 

Additionally, communities can use the structures built for trachoma to fight other diseases. If people around the world work together to combat disease and poverty, everyone’s well-being will improve.

Community Health Services Sustain Health Care Access in Cuba

Health Care Access in CubaWhen blackouts and fuel shortages threaten hospitals across Cuba, it is the doctors, nurses and medical students long embedded in neighborhoods who keep the system running. The de facto blockade of Cuba’s oil supply in recent months has had serious and widespread effects across all of Cuba, notably within the National Health Service (NHS). Representing the nation at the U.N. in September of 2025, Foreign Minister Bruno Parilla described daily challenges facing Cubans: “A grave scenario of prolonged and daily blackouts, difficulties in affording food, insufficient availability of medicines, reduced public transport, limited community services and pronounced inflation, which is eroding real incomes.”

Authorities and community clinics have reorganized services to protect health care access in Cuba. This ensures the continuous availability of life-saving treatments, including oncology care, dialysis and maternal health, across rural provinces. It also maintains regular access to primary family care physicians.

Cuba’s widespread, free-at-the-point-of-use medical system plays a critical role in maintaining access to health care, particularly during periods of economic or energy disruption. The health system’s ability to function under these conditions reflects Cuba’s family doctor and primary health care model. This model is built on principles that protect universal care and strengthen community resilience for all people in Cuba. These key principles form the foundation of Cuba’s strategy for maintaining health care access during humanitarian crises.

Accessibility and Regionalization

These first two principles establish that health care access in Cuba is universal and should remain available regardless of geography, income or social status. Before Cuba’s post-revolution health care reforms, rural Cubans had little to no access to hospital care. Today, “polyclinics,” general medical care centers are found in communities across the country, giving people outside major cities access to health care on a scale not seen since before the Spanish colonization of Cuba.

During the current fuel shortages and electricity disruptions, maintaining accessibility has required reorganizing how doctors and staff deliver care across Cuba. As a result, five million patients, including those undergoing dialysis or chemotherapy, who require constant electricity and regular specialist care, may see changes to their treatment plans.

Hospitals have prioritized electrical power for critical treatments to ensure staff can continue treating the most vulnerable patients. Thousands of cancer patients require ongoing chemotherapy or radiotherapy, procedures that rely on stable electricity. Local health authorities have responded by concentrating patients in facilities with reliable power generators and hospital beds so that treatments can continue uninterrupted.

The newspaper Girón spoke with Yamira López García, the provincial director of Public Health in Matanzas, about the situation. She reaffirmed the government’s commitment to maintaining the operational capacity of all facilities within the public health system and expanding outpatient services so that “no patient will be left without the possibility of treatment.”

The paper also reported that radiotherapy, chemotherapy and dialysis remain available to patients and that authorities have established infrastructure for new admissions. These efforts demonstrate how the system seeks to preserve health care access in Cuba even as logistical conditions deteriorate.

Prevention

Preventive medicine is the central pillar of Cuba’s health care model. Rather than focusing solely on hospital treatment, the system relies on neighborhood doctors and nurses to monitor family health and identify risks early. The NHS has called for doctors to be reassigned to facilities near their residences to strengthen neighborhood clinics and reduce transportation pressures.

Specialists from secondary care institutions have also been temporarily deployed to community polyclinics to ensure local services remain operational. Because this regionalized network already exists, the system can redistribute medical personnel across local facilities without dismantling care. Clinics remain embedded within the communities they serve, helping maintain health care access in Cuba even when transportation and electricity shortages disrupt larger hospitals. 

These visits allow health workers to identify patients who may require urgent care before conditions worsen, reducing pressure on hospitals and helping preserve health care access at the community level in Cuba.

Community Participation

Rather than imposing health care structures on communities, Castro’s system sought to integrate local populations and emphasize organized public participation. Health care delivery, for example, is not limited to professional staff but also involves collaboration among medical institutions, local communities and educational programs. To maintain universal health care access in Cuba, medical students have joined primary care teams in clinics and doctors’ offices. 

As part of their training, students assist with household visits, patient monitoring and public health education. Their work expands the capacity of the neighborhood health system while allowing services to continue despite staffing and transportation challenges. This collective approach strengthens the resilience of local clinics. It ensures that community-based care remains a cornerstone of health care access in Cuba.

International Collaboration

Cuba’s health care strategy also includes international collaboration, with thousands of medical professionals participating in missions across Africa, Asia and Latin America. At the beginning of the COVID-19 pandemic, tens of thousands of Cuban doctors were working in more than 50 countries. Rather than recalling them, the Cuban government asked them to cooperate with host nations in combating the pandemic.

In recent months, many of those host countries have donated thousands of tons of critical aid, reflecting how international cooperation and reciprocal support can lead to better outcomes. The Nuestra América Convoy to Cuba is one such coalition aimed at delivering humanitarian aid based on “cooperation, respect for international law and U.N. values.” Arriving in Havana on March 21, 2026, the convoy is made up of volunteers from around the world and carries food, medicines and energy supplies.

Final Remarks

The energy crisis has tested every link in Cuba’s health care system. The resilience of community clinics and primary care networks demonstrates how strong public health infrastructure can protect health care access in Cuba, even under severe resource pressures. The polyclinic model supports universal accessibility and regionalized services, while prevention and community participation make clinics more adaptable under pressure. This approach offers a potential model for other low-resource settings facing similar shocks.

$28 Billion Pledge Boosts Childhood Anemia Prevention

Childhood Anemia PreventionIron deficiency anemia is the most prevalent, yet preventable, nutrient deficiency-related disease in the world. According to the World Health Organization (WHO), 269 million children younger than 5 are affected, primarily those in low-income countries. At the 2025 Nutrition for Growth (N4G) Summit, global leaders addressed childhood anemia prevention, pledging nearly $28 billion to address the crisis. This investment could change millions of lives; however, the challenge is turning commitments into actions that reach children who need it the most.

Childhood Anemia: Effects on Health, Education and Poverty

Iron deficiency anemia is primarily caused by inadequate nutrient intake. Children in poverty-stricken countries are most at risk as food insecurity prevents balanced meals. Excessive blood loss associated with malaria, a disease currently found in 83 countries, is also a compounding factor of anemia in children. The link between poverty and anemia highlights why it is essential to understand its impact on children’s health, education and future potential.

Anemia causes fatigue, weakness, compromised immunity and, if left untreated, heart problems. Beyond health issues, affected children struggle with attention and memory problems, impacting learning as well as social interactions. The result is poor school performance and increased absenteeism, which affects their access to future educational and career opportunities, further perpetuating the cycle of poverty.

Why Previous Efforts Fell Short

Previous N4G Summits prioritized malnutrition and childhood anemia prevention. Global leaders pledged $23 billion in 2013 to address global malnutrition and $27 billion in 2021 to invest in anemia and food fortification. Sadly, these pledges fell short as a result of weak monitoring, insufficient funding and implementation delays. COVID-19 disruptions additionally prevented 2021 programs from fully reaching target communities.

Based on previous tracking reports, the 2025 Summit has new priorities. With a historic investment of $28 billion, the WHO and global leaders aim to turn commitments into tangible results. The efforts emphasize accountability, targeted interventions and measurable outcomes, supported by data systems to track progress. These changes set the stage for this initiative to make a real difference.

How $28 Billion Supports Childhood Anemia Prevention

Building from previous frameworks, the WHO, in partnership with UNICEF and the Anemia Action Alliance, has developed a comprehensive strategy to address childhood anemia. Their four primary areas for intervention include:

  • Addressing root causes: Programs are being implemented to address the nutritional and infectious causes of anemia. Comprehensive care tackling iron deficiency, malaria and parasitic infections is paramount in reducing the prevalence of childhood anemia.
  • Supplement distribution: In collaboration with national ministries and outreach programs, the WHO and UNICEF will increase women and children’s access to iron and folic acid tablets.
  • Food fortification: Countries are enacting policies mandating the fortification of staple foods such as wheat, rice and salt, which make up the bulk of diets in low-income countries. Fortification with iron helps address the widespread deficiency that contributes to childhood anemia.
  • Health system improvements: The WHO and UNICEF are working with ministries of health to integrate anemia testing into routine health services, provide training to health workers and improve the delivery of supplies.

These efforts aim to create lasting systems that prevent childhood anemia rather than only treating it. When sustained, such progress improves health and boosts education, productivity and economic stability, helping break the cycle of poverty.

Turning Promises Into Progress: Why Transparency Matters

The impacts of anemia go beyond health; it impacts national growth, too. According to the World Bank, anemia in children reduces productivity and learning potential, costing low-income countries up to 4% of their GDP each year. To truly make a difference and reduce poverty across generations, commitments to improving health need to become actions.

That’s why the 2025 N4G Summit emphasizes trust and transparency. Past pledges faltered due to weak data collection and limited accountability. Organizations such as the U.N. and Global Nutrition Report are calling for stronger monitoring systems to ensure this doesn’t happen again. New tracking dashboards are in place to measure outcomes and ensure real progress is being made.

If governments and partners uphold their commitments, this unprecedented $28 billion pledge for childhood anemia prevention could finally create lasting change. It offers a once-in-a-generation opportunity to break the cycle of malnutrition and poverty for generations to come.

HPV Self-Test Kits: Cervical Cancer Screening in El Salvador

Cervical Cancer Screening in El SalvadorCervical cancer is one of the most preventable yet deadly cancers among women worldwide. More than 90% of cervical cancer-related deaths occur in low and middle-income countries, including El Salvador. In this Central American nation, cervical cancer remains the leading cause of cancer-related deaths in women, with limited access to traditional screening programs posing a major barrier to prevention efforts.

A Promising Alternative: Self-Collection

To combat this gap in gynecological care, the Salvadoran Ministry of Health partnered with Basic Health International to pilot self-collected HPV testing in rural areas. In the Cervical Cancer Prevention in El Salvador (CAPE) study, more than 500 women participated in self- and provider-based screening. Many preferred self-sampling, citing privacy, comfort and ease of use. This low-cost alternative has the potential to transform cervical cancer screening in El Salvador, especially for women who were under-screened or had never received a cervical exam.

Self-collection allows women to collect cervico-vaginal samples, often at home, using a small brush. This eliminates the need for a speculum exam. Additionally, this is a game-changer for women in rural areas where clinics are far away and stigma around pelvic exams runs deep. In surveys, nearly 40% of participants preferred self-collection and most of those said they would choose it again for future screenings.

Integrating Self-Tests Into National Guidelines

Thanks to strong evidence from pilot studies and advocacy by public health leaders, El Salvador became one of the first countries in the region to integrate HPV testing into its national cervical cancer screening guidelines. This includes the option for women to collect their own samples, a move that improves access and encourages early detection.

The Ministry of Health is committed to screening 70% of eligible women by 2030, which aligns with the World Health Organization’s (WHO) global elimination strategy. Furthermore, the inclusion of HPV self-collection in national policy marks a critical step toward expanding cervical cancer screening in El Salvador to reach the WHO’s 2030 elimination targets.

Scaling up Nationwide

Since self-collection was introduced, cervical cancer screening in El Salvador has grown rapidly. The country has trained more than 4,500 health care workers and screened more than 145,000 women. Screen-positive women are offered treatment at one of 74 centers across the country. Innovations like self-sampling and portable thermal ablation devices are helping to make these services more accessible and affordable, particularly for women in hard-to-reach areas.

A Model for Other Countries

El Salvador’s success shows how simple, scalable innovations can dramatically increase access to life-saving care. Indeed, by removing logistical, financial and cultural barriers, HPV self-collection empowers women to prioritize their health on their terms. As other low and middle-income countries seek to meet the WHO’s 2030 targets, El Salvador’s model offers hope and a blueprint for equitable cancer prevention.

Healthy Learners: Zambia’s School Health Program

Zambia’s School Health ProgramA Grade 4 pupil in Lusaka coughs during maths class. Instead of sending her home, a teacher, now a trained School Health Worker, opens a tablet, runs through a WHO‑style checklist, dispenses deworming pills, logs the visit and, if needed, fast‑tracks her to a clinic. The entire effort is part of Zambia’s Healthy Learners School Health Program and averages just $1.51 per child per year, which is less than 1% of what the Ministry of Education already spends per pupil.

The Poverty Trap: Preventable Illness = Lost Learning

Worm infections, vitamin A deficiency and other routine ailments quietly siphon school days and future earnings for Zambian children. Absenteeism forces caregivers to miss work too. By moving first‑line care into classrooms, Zambia’s Healthy Learners School Health Program targets that cycle where it begins: illness that keeps kids out of class.

Clinic in a Classroom: How the Model Works

Healthy Learners partners with the Ministries of Health and Education to train and equip teachers as School Health Workers. In 598 public primary schools, more than 5,300 teachers now use a mobile app (built with THINKMD). The app mirrors physician logic to triage, treat mild conditions (deworming, vitamin A, first aid) and fast‑track severe cases to clinics, plugging schools straight into the national health system.

The Numbers That Matter

  • Reach: More than 830,000 students served, about a quarter of Zambia’s public primary school population, with a goal of 2.2 million by 2028.
  • Health Gains: A study found a 38% drop in disease morbidity, a 48% jump in both deworming and vitamin A coverage, a 22% rise in health knowledge and a 52% reduction in the odds of stunting.

These improvements mean fewer sick days now and more substantial earning potential later.

Small Price, Massive Payoff

After an initial setup cost of $10 to $15 per child, the ongoing cost falls to about $1.50 thanks to economies of scale and government integration. That frugality is why Zambia’s Healthy Learners School Health Program is financially realistic for national ownership and replicable elsewhere.

In 2022, the Ministries of Health and Education signed an MoU to scale the program nationally, embedding data systems and training inside state structures. Spring Impact highlights this “design for integration” as the core reason the model can scale without ballooning costs.

A Call to Action

Zambia’s Healthy Learners School Health Program is a ready‑made template for any country where schools reach kids more reliably than clinics.

A child walks back to class, symptoms eased, lesson saved. Indeed, one tablet tap at a time, Zambia’s Healthy Learners School Health Program is proving that health in schools is one of the cheapest, most innovative ways to fight poverty.

Bulgaria’s Air Quality and Disease Prevention

Bulgaria's Air QualityBulgaria’s public health initiatives prioritize air quality and disease prevention. They address critical issues that disproportionately affect low-income communities and exacerbate poverty, promoting a healthier and more equitable society.

Breathe Sofia

In September 2022, the city of Sofia, Bulgaria, launched Breathe Sofia, a project aimed at improving air quality in one of the country’s most polluted cities. It focuses on protecting vulnerable populations by building public support for stronger policies, offering technical guidance for regulations and sharing international best practices.

By reducing air pollution, these efforts can help alleviate poverty by lowering health care costs and improving quality of life, especially for communities most affected by environmental disparities. Beyond health benefits, air pollution reduction also promotes social equity. It supports children’s well-being in impacted areas, increases economic participation and reinforces Bulgaria’s commitment to inclusive development under the European Union’s (EU) sustainability goals.

Bulgaria’s Air Quality

Bulgaria has also launched the New Operational Program on the Environment, allocating $1.77 billion to address water and waste management, biodiversity and air pollution. Since 2021, the program has helped provide cleaner air for 1.3 million people.

Furthermore, as part of its broader sustainability agenda, Bulgaria has prioritized emissions reduction through the National Program for the Improvement of Ambient Air Quality. This strategy drove significant progress between 2018 and 2024, with emissions falling by 66.5%. This reduction directly benefits low-income families by providing cleaner air and supporting healthier, more sustainable living conditions.

Addressing Diseases

To address cancer and chronic diseases, Bulgaria has joined the Joint Action to Prevent Noncommunicable Diseases and Cancer (JA PreventNCD), a three-year EU-funded health initiative. The project aims to reduce the burden of cancer and other noncommunicable diseases (NCDs) across Europe by supporting 22 EU Member States, along with Iceland, Norway and Ukraine. It also focuses on tackling social inequalities linked to NCD risk factors.

With NCDs disproportionately affecting marginalized communities, JA PreventNCD targets the root causes by addressing the link between poverty and poor health. The initiative acknowledges the unequal impact of NCDs on lower socioeconomic groups and promotes equitable access to prevention and care. By focusing on prevention and healthier lifestyles, JA PreventNCD aims to reduce health problems, ease the economic burden of NCDs and contribute to poverty reduction.

Bulgaria’s commitment to rare disease recognition took a major leap in 2005 when it joined the J Project, a Central and Eastern European initiative focused on primary immune deficiencies. Ten years later, this progress led to the establishment of a dedicated expert center at the university hospital. The center provides families in low-resource communities with access to specialized care for rare diseases.

Final Remarks

As Bulgaria works to improve the quality of life for its citizens, it collaborates with national and international programs aimed at disease prevention and air pollution reduction. Supported by initiatives like the Clean Air Fund and the EU partnerships, these efforts create healthier environments and expand access to essential resources in underserved communities through public health and sustainability investments. Indeed, they help pave the way for a more equitable and resilient future.

Sickle Cell Disease in Tanzania

sickle cell disease in TanzaniaSickle cell disease has been a part of life in sub-Saharan Africa for more than 8,000 years, accounting for approximately 6.4% of under-five mortality, according to the World Health Organization (WHO). Sickle cell disease affects between 8,000 and 11,000 infants in Tanzania each year, with six out of every 1,000 children born carrying this genetic “time bomb”.

Without early diagnosis and consistent treatment, up to 90% of these children may not survive past their fifth birthday. To address this, Texas Children’s Global Hematology-Oncology Pediatric Excellence (HOPE) and Baylor College of Medicine Global Health have launched a low-cost program to combat sickle cell disease in Tanzania.

What Is Sickle Cell Disease?

According to the National Institutes of Health (NIH), sickle cell disease is a genetically inherited blood disorder that affects hemoglobin. Hemoglobin is the protein that binds with oxygen in red blood cells as they travel throughout the body. Generally, red blood cells resemble crimson frisbees, gliding through the blood vessels to various organs and tissues. Upon arrival, they distribute oxygen and carry carbon dioxide from the tissues to the lungs for exhalation.

When a person has sickle cell disease, their red blood cells morph into a crescent shape, resembling a traditional farming tool called a sickle. As they become crescent-shaped, the hemoglobin often hardens, causing the blood cells to turn rigid. The sickled cells can then get caught in the vessels, blocking blood flow and causing severe pain.

Causes and Symptoms

These malformed cells are caused by a gene mutation inherited from parents who are both carriers of the recessive gene. According to the NIH, symptoms can develop as early as five or six months. These symptoms usually include yellowing of the skin or the whites of the eyes, often called jaundice and icterus, respectively, extreme tiredness or fussiness and painful swelling of the hands and feet.

As the affected children age, the symptoms begin to intensify exponentially. The NIH states that common symptoms found in sickle cell patients are severe pain events often referred to as “pain crises” or “vaso-occlusive crises,” fatigue, shortness of breath, irregular heartbeat and chest pain, among other abnormalities. Many of these occur when the sickled cells block the blood flow and restrict oxygen delivery to the rest of the body. Most commonly, this is the catalyst for the pain crises, which occur sporadically and can continue for multiple hours or even days.

Global HOPE and Baylor College of Medicine

Texas Children’s developed the Global HOPE program in 2017 to improve the survival of children with cancer and blood diseases in Africa. Its mission is to accomplish this by leading patient care, education and research to equate survival rates to those of the United States (U.S.). Through its Global Health collaboration with Baylor College of Medicine, the organization has become one of the largest distributors of pediatric HIV care on the planet. Its global programs aim to decrease health disparities and provide creative, forward-thinking solutions for improved care and survival rates.

In January of 2025, with the support of Bristol Myers Squibb, a global biopharmaceutical charitable organization, Texas Children’s and Baylor College of Medicine announced that they would be tackling the devastating threat of sickle cell disease in sub-Saharan Africa. The program will begin by rolling out interventions and treatments for sickle cell disease in Tanzania and Uganda. According to the Texas Children’s website, the interventions it has planned are economically advisable and have proven histories of success. They have been implemented in Western countries, often known for leading medical innovation, since the 1980s, with initial pilot trials also returning impressively positive results in Africa. The interventions are just as simple and effective in controlling sickle cell disease in Tanzania.

Prevention and Treatment

For infants, screening and immunizations will be administered. Screening is often done in newborns by pricking the infant’s heel and recovering a blood sample on a lab card. A lab then uses tests such as high-performance liquid chromatography, capillary electrophoresis and isoelectric focusing to separate and identify the components of the sample and attempt to detect the presence of abnormal hemoglobin proteins. Once a sickle cell has been identified in a child, Texas Children’s and Baylor College of Medicine plan to provide a daily penicillin pill for five years due to the increased susceptibility to bacterial infections such as pneumococcus. This will be administered orally until the child is five years old and should prevent the development of bloodstream bacterial infections.

Finally, they also plan to administer a daily dose of hydroxyurea, an oral medicine approved in 1998 by the U.S. Food and Drug Administration for treating sickle cell disease. Hydroxyurea has been found to prevent pain crises and hospitalizations for children. It does so by maintaining the circular flexibility of the red blood cells, allowing easier flow and oxygen delivery throughout the body. This will come as a big win in a country such as Tanzania, where access to health care, especially for children, is extremely limited due to high rates of multidimensional poverty, an unequipped infrastructure and a lack of access for rural populations.

Conclusion

The work of Texas Children’s Global HOPE and Baylor College of Medicine’s alliance has already proven to be successful in the work they have done in HIV and AIDS prevention and treatment. Their work to detect, educate, treat and research has lofty goals of emulating their success in the U.S. With the determination they have brought to the medical world thus far, their initiative provides a hopeful future for all children struggling with sickle cell disease in Tanzania.

How NASA Satellites Prevent Disease Outbreaks

NASA SatellitesIn 1999, The National Aeronautics and Space Administration (NASA) scientists theorized that in the near future, they would be able to track disease outbreaks from space. They were mainly concerned with Rift Valley Fever. This is a disease prevalent in East Africa that is deadly to livestock and occasionally deadly in humans. NASA scientists already had surmised that outbreaks were directly related to El Niño weather events. Areas with more vegetation on abnormally precipitous years breed more disease-carrying mosquitoes. To see the exact areas that would be most at-risk, NASA satellites would need to be able to track differences in the color and density of vegetation from year to year.

Tracking Rift Valley Fever

In 2006, NASA scientists were able to predict and track an outbreak of Rift Valley Fever in East Africa. Even with intervention efforts, the outbreak led to the deaths of over 500 people and cost the regional economy over $60 million due to export restrictions and livestock deaths. Although the researchers could not adequately predict the outbreak then, the results of that mission gave them confidence that they could predict the next outbreak even better the next time El Niño conditions arose.

Ten years later, the NASA team successfully predicted the location of the next potential outbreak. They subsequently warned the Kenyan government before the disease could strike and gave them ample time to prepare. Thanks to the combined efforts of the Kenyan government and NASA satellites, Kenya saw no outbreak of Rift Valley Fever in 2016. The country protected the lives and livelihoods of rural farmers throughout the country and saved millions of dollars.

The success of the Rift Valley Fever prediction models gave the researchers more confidence in their methods. They believed that NASA satellites could predict and halt all manner of outbreaks. Researchers focus on neglected diseases like cholera. These diseases have connections to environmental conditions that hit developing countries and impoverished people the hardest. Newer satellites add the ability to measure variables like temperature and rainfall. Researchers are able to use it more than just the visual data utilized in the initial Rift Valley Fever predictions, thanks to the improved models.

Tracking Cholera

Cholera infects from 1.4 to 4 million people and kills more than 140,000 each year. There are two distinct forms of cholera: endemic and epidemic. Endemic cholera is present in bodies of water primarily during the dry season. This means communities living along the coasts are typically prepared for an outbreak. Epidemic cholera comes about during weather events like floods and often leaves inland communities unprepared for the disease. Due to its infectiousness and connection to weather events, it is the most promising disease that new scientific models have analyzed.

In 2013, a research team successfully modeled cholera outbreaks in Bangladesh using NASA satellites. The real test of the team’s predictive models would come in 2017, however, when it used the same model in a very different part of the world: Yemen. The model worked nearly perfectly. Researchers predicted exactly where the outbreaks would occur nearly a full month in advance. The fact that the models worked in impoverished and war-torn Yemen is especially notable for those concerned with extreme poverty. It means that the previously expensive and dangerous work of entering countries like Yemen in order to do disease research is no longer necessary. Instead, early warning systems can be implemented. But even if they fail, governments and organizations can send vaccines and medicines to exactly the right locations. Cholera outbreaks and their disproportionate death rates among the global poor will hopefully soon be a thing of the past.

Hope for the Future

By halting outbreaks before they begin, international aid dollars can have more efficient use. Prevention is always less expensive than reaction. Information in and of itself is valuable and the more information poverty-fighting organizations have, the better they can spend their dollars to maximize utility and help the most people. As satellite technology advances along with newer predictive models, preventing disease outbreaks could save developing economies and aid organizations hundreds of millions of dollars each year.

Ending Malaria in China

Ending Malaria in ChinaHistorically, malaria has been extensive in China. In the 1940s, 90 percent of the population was considered at risk. In the 1970s, the country suffered 24 million cases of the disease. With the introduction of anti-malarial medicine and urbanization, massive strides have been made to end malaria in China.

In 2010, China launched the National Malaria Elimination Plan (NMEP) with the aim of eradicating malaria from the country by 2020. It pushed for rapid responses to reported cases of the disease, with the 1-3-7 plan outlining a report within one day, investigation within three, and treatment within seven. The plan saw great success and in 2017, no indigenous cases of malaria were detected.

China is not yet completely free of malaria. It is difficult to contain the disease at the country’s borders and those in poverty are especially at risk.

Background

The Yunnan Province consistently experiences a high number of malaria cases due to its constant interaction with neighboring counties. The wealthiest counties in Yunnan are central and surround the capital city Kunming. Among the 26 border counties, only two have an infection rate below one in 10,000, and nine have rates above 10 in 10,000. In addition, 21 of these counties are the poorest in the province. Researchers have called for more resources to be diverted to Yunnan.

The remaining cases of malaria in China pour in from neighboring countries, with 19,154 cases from 68 countries documented between 2011 to 2016. In the majority of cases, the disease was carried by returning Chinese workers, mostly from Myanmar, Ghana or Angola, all countries that rank below 160th highest GDP per capita in the world.

Despite these challenges, the country has made significant strides to combat malaria. The first major effort began in 1955, with the launch of the National Malaria Control Programme, a push to improve irrigation and insecticide use throughout the country. China reduced malaria deaths by 95 percent, and suffered only 117,000 cases of the disease, by 1995.

In 2003, China received aid from the Global Fund to fight AIDS, tuberculosis and malaria. Global Aid distributed over $100 million throughout the world over two years. In China, this reduced the number of annual cases below 5000.

The 2010 Program was a synthesis of a national effort. About 13 departments came together, including the ministries of health, education and the military to end malaria. According to He Qinghua, Deputy Director-General of the Bureau of Disease Prevention and Control at China’s National Health Commission, a large portion of the effort focused around involving the government at every level of control. If a ruling was made in the capital, it had to be translated into every local government.

Since 2014, the Chinese government has paid for the entirety of its fight against malaria, though it recognizes the importance of early support from external funds like the Global Fund. Yang Henling, a professor at the Yunnan Institute for Parasitic Diseases, further states the need to continue efforts, lest malaria return.

China Turns to Help Other Nations Eradicate Malaria

New South, a Chinese company, has begun working to eliminate malaria in Kenya, where 70 percent of the population is at risk of the disease. New South has already been working in Comoros.

New South advocates for the use of MDA, the primary drug involved with treating malaria in China. While many western organizations, including the Bill and Melinda Gates Foundation, focus on preventing mosquitoes from spreading malaria, New South emphasizes treatment in humans. Dr. Bernhards Ogutu, who has been fighting malaria in Kenya for decades, believes that Chinese support will have malaria eradicated in some areas of Kenya within only five years.

New Methods of Preventing Disease in Ethiopia

Disease in EthiopiaAs of 2018, Ethiopia has a population of over 107 million people. The country also boasts the highest livestock population in Africa, with around 52 million cattle and 36 million sheep. With nearly 80 percent of Ethiopia’s people dependent on livestock for income and sustenance, they are in constant contact with these animals. This puts them at high risk of contracting zoonotic diseases. In order to prioritize and prevent disease in Ethiopia, the United States CDC developed a semi-quantitative tool and held a workshop to identify the biggest concerns for human and animal health.

High-Risk Diseases

Forty-three contractible zoonotic diseases were evaluated at this workshop. Criteria were based on the severity of a disease in humans and the proportion of human disease based on animal exposure. The five diseases that were identified as having the highest need for prevention were rabies, anthrax, brucellosis, leptospirosis and echinococcosis. The goal of this workshop was to focus on better prevention and control strategies and to create programs that will better prepare the population to prevent diseases in Ethiopia.

Along with facing a higher risk of contracting zoonotic diseases than other countries in Africa, Ethiopia also experiences high risks of other deadly illnesses, such as malaria and AIDS. As of 2016, diarrheal diseases and lower respiratory infections cause the most deaths in Ethiopian children. With water sometimes being hard to access, due to a massive drought starting in 2011, the citizens are forced to drink water that can carry many kinds of life-threatening bacteria.

Preventing Disease in Ethiopia

Handicap International is doing its part to lessen the spread of disease in Ethiopia by providing clean water. They currently have placed three underwater storage tanks in Ethiopia that fill up with water during the rainy seasons which provide clean drinking water when rain is less abundant. Each tank can provide water for 1,500 people for almost two months.

Handicap International also provides training to health workers and citizens in Ethiopia. When people are more educated about the causes and effects of diseases, they are more capable of doing things to prevent contraction and spread. Along with training, the organization also distributes hygiene kits to various facilities.

The United States CDC is also working closely with Ethiopia’s Ministry of Health to implement a stronger HIV program in the country. With a data-driven approach, they are finding more effective ways of counseling and informing the people of Ethiopia, along with creating more appropriate testing strategies.

With so many possible ways of contracting a disease in Ethiopia, it’s no wonder that many organizations have made prevention and education a priority. Because the citizens of Ethiopia rely so much on livestock, they have a much higher risk of disease than many other countries. By providing them with clean water and the opportunity to learn how to prevent the spread of disease, they are on the fast track to higher mortality rates and less illness.
