Sterile Fly Barrier in Central America Saves Lives

Sterile Fly BarrierThe parasitic fly Cochliomyia hominivorax, commonly known as the New‑World screwworm (NWS), inflicts the devastating disease myiasis on livestock by burrowing its larvae into living tissue. Since the 1950s, Panama has maintained a pioneering sterile fly barrier in Central America to halt its northward spread.

More than 100 million sterilized male flies are released each week along the Panama–Colombia border, ensuring that emerging females lay infertile eggs and preventing NWS populations from taking hold. For rural communities, many people live in extreme poverty, protecting their herds often means the difference between starvation and survival.

The Screwworm’s Mode of Attack

Female NWS flies deposit eggs in fresh wounds. Within hours, the larvae hatch and begin excavating into living flesh in a spiraling motion that inspired its common name. As these maggots feed, they create deep, pus‑filled lesions that, without prompt removal, lead to severe inflammation, systemic infection and often the death of the animal.

Historically, livestock owners resorted to harsh chemical larvicides, branding techniques or manual extraction to combat infestations. These methods were costly, traumatic for the animals and frequently insufficient to prevent herd-wide losses.

Operation of the Barrier System

The Panama–U.S. Commission for the Eradication and Prevention of Screwworm (COPEG) oversees the production and release of sterile flies. In a specialized rearing facility near Pacora, screwworm larvae are raised on artificial diets under strict international standards before being sterilized using gamma irradiation.

The resulting sterile males are dispersed from aircraft across the Darien region to establish a continuous barrier. Since its permanent establishment in 2004, this sterile fly barrier in Central America has prevented reinvasion from South American endemic zones and safeguarded livestock populations to the north.

Economic Impact and Performance Metrics

Before the Sterile Insect Technique (SIT) was implemented, screwworm infestations caused annual losses exceeding $300 million in Central America through animal deaths and treatment expenses. At the same time, the U.S. faced more than $900 million in direct costs each year. By neutralizing reinvasion threats, the barrier delivers an estimated $1.3 billion in annual economic benefits across the region. On a household level, smallholder farmers gain an additional $200 to $300 per year, resources that can be allocated to nutrition, education and health care.

The United Nations Food and Agriculture Organization (FAO) emphasizes that impoverished livestock owners, who often hold only a few animals as their sole asset, are disproportionately affected by parasitic outbreaks. Furthermore, the loss of even a single bovine can plunge a family into an existential crisis. By protecting up to four million of the most vulnerable rural residents in Mexico and Central America, the sterile fly barrier in Central America secures their primary source of income and food. This directly interrupts the cycle of extreme poverty and prevents further social deprivation.

Future Outlook

With climate instability accelerating parasite migration and global trade increasing the risk of cross‑border spread, sustained funding for COPEG remains essential. Moreover, the SIT model holds promise for tackling other myiasis‑causing species and livestock diseases. Expanding this approach to additional endemic areas could further stabilize agricultural livelihoods and serve as a cornerstone strategy for global poverty reduction.

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.

Drones Reducing Tuberculosis in Nepal

Tuberculosis in Nepal: How Drones are Helping Tuberculosis has long affected rural nations across the globe, but the crisis in Nepal is particularly concerning. In 2023, 68,000 people in the country had tuberculosis, nearly a third of whom died. Tuberculosis also remains among the top five causes of death in Nepal. Exacerbated by limited access to medical treatment and high transmission rates, the disease continues to pose a serious threat. However, new technologies—including drones—offer potential solutions that could transform health care delivery in Nepal and beyond. 

A Persistent Threat in Nepal

Tuberculosis is a serious infectious bacterial disease that spreads through coughs and sneezes. When detected and treated early, it is both preventable and curable. However, geographic and economic barriers make tuberculosis more difficult to manage in Nepal. Approximately 50% of Nepalis must travel between six and eight hours to reach a health care facility. It is the isolation and lack of infrastructure in the rural regions, where 80% of Nepalis reside, that deepens the inaccessibility of medical care. With these roadblocks, fewer citizens actively seek out care and the diagnosis of tuberculosis is consistently delayed. As a result, almost 70% of Nepalis are carriers of the disease and may face serious consequences in the future.

The Danger of Delayed Treatment

Once exposed to tuberculosis, it is important to seek out medical care quickly to begin treatment and prevent the spread of this potentially deadly disease. However, because seeking medical treatment in Nepal is such a burden, many seek it out very infrequently or not at all. The longer people wait to seek tuberculosis treatment, the more serious the illness can become. By waiting for an official diagnosis and treatment, they risk increased rates of community transmission and potential health issues. This transmission and these complications have led to significant economic decline. Many become bedridden or unable to work as a result of the disease, leading to increased poverty rates. Telemedicine, however, is making notable progress. Organizations have begun using drones to diagnose and treat tuberculosis patients more efficiently.

Using Drones to Fight Tuberculosis in Nepal

A number of institutions, including WeRobotics, Stony Brook University and Nepal Flying Labs, have been utilizing cargo drones to combat tuberculosis in Nepal. These drones collect samples from individuals suspected of having tuberculosis and deliver them for testing. The same drones also help administer treatment. Tuberculosis treatment often spans several months, making it difficult for patients in remote areas to complete. However, with the support of these drones, a technology known as e-DOTS can facilitate therapy remotely.

Building Toward Health Equity

The efforts made by these international organizations are enabling tuberculosis diagnosis and treatment. Technology like these drones is not only helping to reduce the prevalence of tuberculosis, but also represents a step toward bringing medical care to rural areas in need. Telemedicine is actively empowering rural communities by providing access to timely care. So far, these drones have tested more than 700 people in rural Nepali communities. It is the hope of many that technology like this will continue to cross borders and support international poverty reduction.

Strengthening Disease Prevention in Sudan 

Disease Prevention in SudanSudan has faced severe conflicts creating detrimental humanitarian crises, crippling its health care systems and leading to increases of fatal diseases, including malaria and cholera. This humanitarian crisis has left 15.8 million people in need of humanitarian aid. With this conflict increasing constantly, it has now left half of Sudan’s population (30.4 million) people in desperate need of aid. Where refugee camps have been set up to provide aid to people has contributed to this increase in diseases by providing poor sanitation, enabling the spread of these diseases. Here is information about disease prevention in Sudan.

Health Challenges Under Conflict

A major challenge Sudan faces in tackling the spread of disease and poverty begins with child immunization. The most prevalent diseases within Sudan include malaria, cholera, measles and dengue fever affecting 3.4 million children under the age of 5 years old. Ongoing conflict has severely disrupted vaccination efforts, worsening children’s access to aid as well as making it increasingly difficult to reach these children with essential, life-saving immunizations. While UNICEF continues to provide critical support in delivering vaccines, sustained investment and stability are essential to protecting public health. UNICEF has been providing support to Sudan since 1952, and in 2024, it helped more than 9.8 million Sudanese individuals access sanitary water and provided education and psychosocial care to 2.7 million children and caregivers. To effectively prevent the spread of infectious diseases, Sudan must prioritize the restoration and continuity of its national immunization program.

Non-communicable diseases (NCDs) represent the leading cause of morbidity worldwide, accounting for 71% of global deaths, and they are becoming more and more prevalent in Sudan. Data from the NCD Progress Monitor shows that the percentage of NCD related mortality had increased from 32% in 2015 to 54% in 2022. Sudan’s progress in implementing NDC policies has been slow as the country achieved five of the 19 NCD targets in 2022.

Organizations Assisting Sudan

Despite immense challenges, several global aid organizations are making an impact, including UNICEF and World Vision who have enabled Sudan’s development by helping individuals who have been directly affected by this ongoing conflict by providing necessary education, food and water and shelter. World Vision has been able to reach more than 3 million individuals, providing them with emergency assistance in Sudan’s unstable climate, making a significant impact. These organizations help to boost social development in Sudan, ultimately aiding them to reduce levels of poverty and increase individual’s livelihoods.

Action Against Hunger is an organization that is fixated on providing care to individuals experiencing this violence and ongoing conflict. It has been working in Sudan since 1985 to provide fresh water and food as well as malnutrition treatment to those deprived of food. From 2023-2024, it has helped more than 815,000 Sudanese people access food by working in 15 different locations in Sudan to reach the optimum number of people. This organization has also been growing rice in flood waters and farming onions, helping to create new emergency services and rebuild livelihoods, ultimately contributing to the resistance of poverty in Sudan.

Advancing With Sustainability and Purpose 

After the breakout of the war in 2023, the International Rescue Committee (IRC) established a prevalent presence in Al Jazirah State where health and nutrition services were provided and assisted 400,000 Sudanese refugees prior to the War. The IRC established a WASH program – which is an integrated water, sanitation and hygiene program – to help disease prevention in Sudan.

Health Care Crisis: 4 Diseases Impacting Kenya

Diseases Impacting KenyaKenya’s health care system has profoundly suffered as problems like corruption, lack of adequate resources, systemic malpractice, suboptimal policy-making, and Kenya’s ever-increasing poverty rates, amongst other severe issues, pervade Kenya’s fragile health care sector. The current climate crisis has also ignited further issues regarding Kenya’s health care system, as the rate of Neglected Tropical Diseases (NTDs) has drastically increased in recent years. Here are four diseases impacting Kenya.

Malaria

In 2022, Kenya reported around 5 million cases of malaria, with more than 12,000 Kenyans dying as a result of the outbreak. Lack of rainfall and high temperatures have exacerbated the already dire risk of Malaria contamination, as Kenya’s lack of rainfall has created environmental conditions that are highly conducive to Malaria exposure.

Extreme changes in Kenya’s weather patterns have attracted a breed of mosquito, Anopheles Stephensi, which serves as an avid transmitter of malaria. Studies have concluded that the resurgence of the Anopheles Stephensi population in Kenya could potentially expose around 126 million Kenyans to Malaria.

HIV/AIDS

Kenya currently has the seventh largest percentage of people infected with AIDS/HIV globally. Due to the erroneous distribution of health care facilities across Kenya, faulty educational policies and cultural/systemic gender norms, AIDS/HIV reigns as one of the leading causes of death in Kenya. The HIV/AIDS epidemic disproportionately affects women, especially young women (15-24), as women and young girls make up two-thirds of the current percentage of Kenyans living with AIDS/HIV. The current U.S. foreign aid freeze has only exacerbated this issue, as foreign aid has historically accounted for 40% of Kenya’s HIV/AID preventative resource supply.

Cholera

Kenya has historically been a hotspot for frequent Cholera outbreaks and has continued to affect the Kenyan population due to poor sanitation infrastructure and lack of access to clean water. Heavily populated areas like refugee camps, informal settlements, and other highly populated and poorly regulated areas have especially served as hotspots for Cholera contamination.

While efforts like nationwide vaccine distribution, an increase in research towards Cholera prevention/preparedness, and an increase in policy highlighting health care reform in Kenya have helped mitigate outbreaks in recent years, Kenya has had a Cholera outbreak almost every single year since its first outbreak in 1971.

Tuberculosis

In 2016, Tuberculosis was the fourth-leading cause of death in Kenya, and the reported cases of TB contamination have increased sixfold in the last 15 years.  The COVID-19 pandemic only exacerbated these rates, as the percentage of Kenyans who contracted Tuberculosis increased from 49% in 2019 to 61% in 2020. While the spike in Tuberculosis rates has since decreased as the turbulence of the pandemic has decreased, the 2020 Tuberculosis outbreak represents the severe fragility of Kenyan’s health care sector, as statistics have repeatedly shown that the slightest economic, political, health care, or societal issue can seriously exacerbate an already extremely vulnerable healthcare system.

The Future

Though many issues continue to fray the fabric of the health care sector in Kenya, there is hope for the welfare of Kenyan citizens. In 2024, President William Ruto implemented the Social Health Insurance Fund, mandating health care coverage for citizens nationwide.

NGOs like UNICEF and the World Health Organization (WHO) continue to implement immunization programs to reduce diseases impacting Kenya.  Though much work is still necessary when it comes to health care reform in Kenya, the shift in political attention towards healthcare reform, coupled with the persistence of NGO efforts to supply Kenya with the proper resources to combat disease outbreaks, establish that hope for the improvement of Kenya’s fractured healthcare system remains steadfast.

Combating Mold and Poor Air in Informal Settlements

Invisible Threat: Combating Mold and Poor Air in Informal Settlements to Boost HealthInformal settlements, often characterized by dense populations, inadequate infrastructure and precarious living conditions, house millions of people worldwide. While visible challenges like the lack of sanitation and access to clean water are widely recognized, a serious and often overlooked threat exists within the very structures these communities rely on: mold and poor air quality. This ongoing issue significantly affects public health, contributing to chronic illnesses and undermining the overall well-being of residents.

The built environment in informal settlements worsens the problem. Residents often construct dwellings from salvaged or low-cost materials that provide minimal insulation and poor ventilation.

Overcrowding is common, further limiting air circulation and increasing humidity. Additionally, many residents rely on open fires or rudimentary stoves for cooking and heating and this releases harmful pollutants into the already confined spaces. The combination of moisture, poor ventilation and indoor pollution creates ideal conditions for mold growth and contributes to dangerously poor air quality in informal settlements.

Health Impacts of Mold and Poor Air

Exposure to mold and poor air in informal settlements has far-reaching health consequences, particularly for vulnerable populations like children, the elderly and individuals with preexisting respiratory conditions.

  • Respiratory Illnesses. Mold spores, when inhaled, can trigger allergic reactions, asthma attacks and other respiratory problems. Chronic exposure to indoor air pollutants, including particulate matter and volatile organic compounds from cooking fires, significantly increases the risk of acute respiratory infections, chronic obstructive pulmonary disease (COPD) and even lung cancer. Children, whose respiratory systems are still developing, are particularly susceptible to these adverse effects.
  • Allergic Reactions and Skin Conditions. Beyond respiratory issues, mold can cause a range of allergic reactions, including skin rashes, itchy eyes and nasal congestion. The damp and unhygienic conditions often associated with informal settlements can also exacerbate existing skin conditions and contribute to new ones.
  • Cognitive and Developmental Impacts. Studies have begun to link exposure to poor indoor air quality, particularly in early childhood, with negative impacts on cognitive development and academic performance. This creates an unfortunate cycle where environmental factors undermine educational opportunities, perpetuating poverty.
  • Mental Health. The constant presence of dampness, mold and poor air in informal settlements can also contribute to stress, anxiety and depression among residents. The feeling of living in an unhealthy and unsafe environment can take a significant toll on mental well-being.

Potential Solutions and Ongoing Efforts

Addressing mold and poor air quality in informal settlements requires a multi-faceted approach that considers the unique challenges of these communities.

  • Improving Housing Design and Materials. Simple design modifications, such as strategically placed windows and vents, can significantly improve airflow and reduce humidity. Educating residents on preventing water intrusion and managing leaks could also play a crucial role. Implementing affordable and moisture-resistant building materials can also help. Organizations like Habitat for Humanity often focus on improving housing conditions, including better ventilation and moisture control. Exploring the use of locally sourced, sustainable materials that offer better insulation and breathability can potentially provide long-term solutions.
  • Enhancing Indoor Air Quality Practices. Promoting access to and adoption of cleaner cooking technologies, such as improved cookstoves or alternative fuels, can significantly reduce indoor air pollution. The Global Alliance for Clean Cookstoves promotes the use of these solutions. Educating residents on simple practices like opening windows when cooking, drying clothes outdoors and maintaining regular cleaning can make a significant difference. Proper waste disposal reduces the presence of damp organic matter that can contribute to mold growth.
  • Community Engagement and Education. Informing residents about the health risks associated with mold and poor air and empowering them with practical solutions is paramount. Supporting local initiatives that focus on improving housing conditions and environmental health can lead to sustainable change. Organizations like Slum Dwellers International (SDI) often work with communities to identify and address their housing and infrastructure needs. Establishing community-based health monitoring programs can help track the prevalence of respiratory illnesses and other health issues linked to indoor air quality, allowing for targeted interventions.
  • Policy and Urban Planning Interventions. Granting secure land tenure to residents of informal settlements can incentivize them to invest in improving their homes and living conditions, knowing they won’t be evicted. Investing in basic infrastructure like drainage systems, piped water and electricity can reduce dampness and the reliance on polluting energy sources.
  • Integrated Urban Planning. Incorporating health considerations into urban planning for informal settlements, with a focus on ventilation, open spaces and access to services, is crucial for long-term public health. UN-Habitat supports inclusive and sustainable urbanization.

A Healthier Future for Informal Settlements

Addressing mold and poor air in informal settlements appears to go beyond improving housing; it also involves safeguarding public health, strengthening resilience and reducing poverty linked to environmental conditions. Implementing strategies that combine improved housing, cleaner practices, community engagement and supportive policies can help mitigate these risks and improve outcomes for affected communities.

Trachoma in Burundi: How Burundi Beat Trachoma

Trachoma in BurundiAfter a long history of trials and tribulations, the WHO has declared Burundi free of trachoma as a public health risk. This marks a major milestone in the country’s health, as only seven others in its region have achieved such a feat. The World Health Organization (WHO) celebrates this milestone not just as Burundi eliminated trachoma, but as the first neglected tropical disease the country has successfully eradicated.

The Impact of Trachoma

Trachoma is a bacterial eye disease caused by Chlamydia trachomatis. It remains a public health problem in 32 countries, primarily in impoverished regions with weak or nonexistent water, sanitation and hygiene infrastructure. The disease spreads through direct contact with the eye and nasal discharge from infected individuals, especially children, or indirectly through flies that have come into contact with these secretions.

In severe cases, blindness from trachoma is irreversible, making early intervention critical. Globally, trachoma is the leading infectious cause of blindness, with millions of people at risk, particularly in sub-Saharan Africa. The disease disproportionately affects women and children, who are often the primary caregivers and more likely to be in close contact with infected individuals.

In Burundi, poor access to clean water and proper sanitation, especially latrines, has historically contributed to the spread of disease. Rural areas often rely on shared or open defecation sites, which attract flies and increase exposure risk. Limited public awareness and inadequate hygiene education further exacerbated the situation, allowing trachoma to persist unchecked for years.

Progress Over Time

According to baseline surveys conducted in 2007-2010, more than 5% of children aged 1-9 had trachoma, indicating that it was endemic in multiple parts of the country. WHO intervened with its SAFE strategy and provided aid across 12 districts. The government of Burundi also cooperated by following WHO guidelines and mapping the disease. Although WHO aimed to eliminate trachoma by 2020, Burundi missed this target due to delays in implementing the strategy across several regions.

From 2018 to 2021, the National Institute of Health (NIH) conducted a public health survey to record the baseline impact of trachoma on Burundi. The results showed that the prevalence of trachoma in Burundi exceeded the ideal threshold and that only around 8% of households had access to sanitary latrines. In 2023, however, things had changed. The WHO reported that, among several other countries, Burundi had met the threshold for eliminating trachoma.

It accomplished this by successfully implementing the SAFE strategy across the country and increasing sanitation (though it is still relatively poor). After two years of consistently meeting the threshold, the WHO declared Burundi free of trachoma as a public health risk.

Final Remarks

Burundi’s trachoma elimination reflects years of persistent effort, collaboration and community health interventions. While challenges remain in sanitation, this success proves the country can overcome major public health threats with sustained action.

Chagas Disease in Bolivia: A Public Health Crisis in Rural Areas

Chagas Disease in Bolivia: A Public Health Crisis in Rural Areas Bolivia is a landlocked country in South America, bordered by Brazil to the north and east, Paraguay and Argentina to the south and Chile and Peru to the west. With a population of more than 12 million people, Bolivia is one of the most culturally diverse nations on the continent, home to numerous Indigenous groups. Politically, it is a presidential republic and around 78% of its population identifies as Roman Catholic. Despite progress in democratization and economic development, Bolivia still grapples with poverty, limited access to health care in rural areas and stark regional inequalities.

When it comes to public health, Bolivia faces a unique and often overlooked challenge: Chagas disease. Caused by a parasite transmitted by blood-sucking insects, this tropical disease has quietly affected hundreds of thousands, particularly in impoverished, rural communities. Bolivia has one of the highest rates of Chagas infection in the world, making it both a public health burden and a social justice issue. This article explores the reality of Chagas disease in Bolivia and the ongoing efforts to fight it.

Chagas Disease in Bolivia

Chagas disease in Bolivia, caused by the parasite Trypanosoma cruzi, continues to pose a serious public health challenge across Latin America and Bolivia remains one of the most affected countries. The disease is widespread across Bolivia, with seven out of the country’s nine departments considered endemic, regardless of altitude. Although major international health efforts, especially those targeting insect vectors and the safety of blood transfusions, have led to a significant decline in infection rates over the past two decades, the burden is still considerable.

By 2005, Bolivia reported around 620,000 cases of infection, down from more than a million in the mid-1980s. Before large-scale control efforts began in 2000, infection rates in Bolivia were alarmingly high, with 90% of adults infected. In 2025, approximately 80% of Bolivian territory is considered endemic. Despite progress, health authorities still diagnose more than 10,000 new cases each year.

The Knowledge of Citizens

People living in rural parts of Bolivia are much more familiar with the insect that spreads Chagas disease. In many rural communities, more than 80% of people could easily recognize the vinchuca, a blood-sucking bug responsible for spreading the parasite. In contrast, only about half of the residents in cities like La Paz and around two-thirds in Santa Cruz were able to identify it correctly. Many rural communities know when it’s most active—often during hot and dry weather—and describe how it enters homes from nearby forests or hides near animal shelters. Locals also talk about its nighttime activity and blood-feeding habits. Interestingly, some communities have noticed a decline in the number of vinchucas in recent years, though the threat is still very real.

Fighting the Illness

Since 2015, Médecins Sans Frontières has been working with Bolivia’s Ministry of Health to improve care for Chagas disease, especially in remote rural areas. One of its most innovative efforts is eMOCHA, a mobile system that allows people to report sightings of triatomine bugs (vinchucas) via free SMS messages. The system uses GPS technology to send technicians directly to affected homes for fumigation and follow-up. Previously, this process could take up to a month—now it happens within days. The pilot project in Narciso Campero Province has shown promising results and may be expanded nationwide or adapted for tracking other diseases.

MSF has also provided training to rural health centers, donated medical supplies like electrocardiography devices and rapid tests and helped treat hundreds of Chagas patients in areas like Monteagudo. Its model suggests that it’s possible to deliver diagnosis and treatment at the primary care level—even in Bolivia’s most remote communities. MSF is now working on a comprehensive manual, in partnership with the Ministry of Health, to help scale the program to other endemic regions.

Looking Ahead

While often overlooked, Chagas disease remains a daily reality for many Bolivians—especially those in rural areas. With the impact of community knowledge, international support and smart technology, progress is underway. However, the road to full disease control remains long and sustained investment is essential.

Organizations Advancing Disease Prevention in Serbia

Disease Prevention in SerbiaSerbia, a country in the Western Balkans between Southeastern and Central Europe, faces many diseases. It is suffering from the dual burden of communicable and noncommunicable illnesses to the growing threat of antibiotic-resistant bacteria spreading across Europe. Health organizations are working relentlessly to strengthen disease prevention efforts in Serbia.

European Center for Disease Prevention and Control

Over the past few months, the European Center for Disease Prevention and Control (ECDC) has visited Serbia. It aims to better understand the strengths and weaknesses of Serbia’s handling of communicable diseases, antimicrobial resistance (AMR) or antibiotic-resistant bacteria.

AMR is a major global concern as antibiotic use continues. Within the European Union (EU) alone, 35,000 people die each year from antimicrobial-resistant bacteria. The visits by ECDC experts ensure that roadmaps can be produced to follow AMR trends across the country, focusing on important sectors such as public safety, human and animal health.

The ECDC organized these visits using a “One Health” approach. The approach is a collaborative, multi-sectoral goal to achieve positive health for humans, animals and the environment, recognizing that the health of these three groups is interconnected. Using the approach, the EU hopes to increase disease prevention in Serbia and throughout Europe.

In addition to supporting the One Health initiative, the ECDC visited Serbia to help strengthen the surveillance of communicable diseases. On March 18, 2025, the agency released a report on its visit outlining several key recommendations:

  • Case definition revision. Revise case definitions within Europe’s most recent legal framework to understand “notifiable” diseases at the EU level in 2025.
  • Decrease surveillance burden for data providers. An automatic “integration of clinical and laboratory data” will decrease the chance of error within the system.
  • Improve notification timelines. Hold more meetings with stakeholders to collect overviews of notifications, which will aid in the surveillance of diseases.

The World Bank Group

The World Bank Group began a Noncommunicable Disease Prevention and Control Project for Serbia to aid in improving the Serbian health system. Efforts within the project include five main goals:

  • Improving the competence of providers.
  • Increasing accessibility to services.
  • Strengthening clinical and public health services.
  • Supporting project management, monitoring and assessment.
  • Improve government response in cases of emergency.

The World Bank Group initiated the project in December 2024. Efforts in the project are primarily focused on health facilities and construction, with a secondary focus on health and a tertiary focus on public administration. While the completion ratings and results have yet to be reported, the World Bank Group has reported “satisfactory” reviews for its management and progress in achieving the project goals.

Conclusion

The initiatives taken by groups like the ECDC and the World Bank Group are the first but the most important steps in securing a healthy future for the people in Serbia and worldwide. Suppose projects like the One Health approach improve Serbia’s prevention and control of disease. In that case, the broader application of this method can improve health systems in other developing countries.

Clearing Invasive Water Weeds in Senegal Fights Disease

Clearing invasive water weeds in SenegalIn rural northern Senegal, a surprising anti-poverty strategy is taking root: cutting down invasive aquatic weeds. These plants, often seen as nothing more than a nuisance, are now at the center of a low-cost, community-led solution to two pressing issues: disease and declining farm productivity. Local villages are improving public health and raising agricultural incomes by removing vegetation that hosts disease-carrying snails and turning it into compost.

Schistosomiasis: A Barrier to Health and Economic Growth

This initiative targets schistosomiasis, a parasitic infection spread by snails that inhabit stagnant water. The disease affects more than 200 million people globally, mostly in sub-Saharan Africa. Infected individuals, especially children, suffer from fatigue, stunted growth and organ damage, which limit both education and income-generating potential. Senegal’s Saint-Louis region has long been a hotspot for the disease.

However, rather than relying solely on drug treatments, researchers from Cornell University and the University of Notre Dame partnered with eight Senegalese villages to try a local intervention: vegetation removal. Over three years, communities cleared more than 400 tons of invasive aquatic weeds from rivers, lakes and irrigation points. Within months, snail populations dropped by and schistosomiasis infections among children declined significantly.

Composting Waste Into Agricultural Wealth

The removed invasive weeds were composted and used to fertilize local crops such as onions, peppers and rice. Farmers who used the compost reported better soil quality, larger harvests and reduced need for synthetic fertilizers. As Molly Doruska, lead author of the study, explained, “This is about really thinking hard about the microeconomics in the cycle of poverty and disease, really thinking hard about households making decisions and the tradeoffs that they’re facing.”

Researchers developed a bioeconomic model to estimate the long-term impact of the intervention. The results were promising: communities that participated in vegetation removal and composting saw improved household incomes and lower rates of schistosomiasis. The low cost of implementation, using only machetes, baskets and compost pits, makes it both scalable and sustainable.

Environmental and Gender Benefits

The strategy yields environmental wins as well. Clearing invasive water weeds in Senegal helps restore freshwater ecosystems, reduces erosion and improves access to water. The composted material replaces chemical fertilizers, cutting input costs and supporting soil health. The approach also has significant gender implications. In many rural households, women are primarily responsible for water collection and caregiving. With fewer children getting sick, women could have more time for farming, education or income-generating activities.

Beyond physical health, the intervention contributes to long-term social development. Reduced infection rates mean more children can attend school regularly without suffering from the fatigue or pain associated with schistosomiasis. In addition, the project has sparked environmental awareness.
