Abidjan Cholera Outbreak: A Preventable Crisis Fueled by Poverty

Abidjan Cholera OutbreakOn the muddy quay of Vridi Akobrakré, a small fishing village just outside Abidjan, the economic capital of Côte d’Ivoire in West Africa, a Red Cross volunteer pours treated water into the hands of a mother. Her children splash barefoot in a stagnant lagoon, unaware that just days earlier, three of their neighbors died from severe diarrhea. At this moment, the Abidjan cholera outbreak is more than a headline. It is a preventable crisis, driven by poverty and poor sanitation.

The Abidjan Cholera Outbreak and Emergency Response

On June 5, 2025, the Pasteur Institute identified Vibrio cholerae in the water. This bacterium causes cholera, a severe diarrheal disease that can be fatal within hours if left untreated. Health authorities immediately confirmed a cholera outbreak in Abidjan — the first in 15 years. The rainy season had just started, with flooding quickly spreading contaminated water. The dense housing of the most impoverished neighborhoods further fueled the outbreak, resulting in 491 confirmed cases and 20 deaths.

The government executed a swift emergency response. Water trucks delivered clean water to affected neighborhoods and temporary treatment centers opened for rapid patient care. Local health teams collaborated with the World Health Organization (WHO), which provided support for water treatment, chlorine distribution and hygiene education. NGOs such as UNICEF and the Red Cross established hand-washing stations and trained volunteers to monitor symptoms within the community.

Poverty and Neighborhood Vulnerability

Vridi Akobrakré, where the bacterium was first confirmed and similar informal settlements around Abidjan remain highly vulnerable. Homes are built above lagoons and most have no latrines or sewage systems. Flooding spreads contaminated water through streets, schools and marketplaces.

Poverty compounds the risk. Families cannot afford safe water and crowded homes make it difficult to maintain proper hygiene practices. The repeated vulnerability of these neighborhoods shows that emergency measures alone cannot prevent future outbreaks. Without structural changes, cholera will continue to strike the poorest communities.

NGO Response and Preventative Solutions

NGOs play a crucial role in addressing immediate risks and building resilience. The Red Cross distributes chlorine tablets and treats water points. UNICEF runs hygiene campaigns in schools and markets. Médecins Sans Frontières operates mobile treatment centers and trains rapid response teams. Experts report that ongoing monitoring, broader distribution of hygiene kits and public awareness campaigns are essential to prevent future outbreaks.

Preventing another cholera outbreak in Abidjan also requires long-term investment. Governments must build sewage networks, drainage systems, formal latrines and pipe clean water for low-income neighborhoods. Equitable urban planning and continuous hygiene education help communities adopt safer practices. Subsidized access to safe water, community sanitation programs and strengthened health systems, along with the establishment of surveillance and rapid response teams, are crucial.

Since the cholera outbreak began, hygiene campaigns have reached thousands of schoolchildren, teaching proper handwashing and safe water practices. Early signs suggest these interventions are slowing the spread of cholera. However, experts warn that without continued support and infrastructure improvements, outbreaks will recur.

Turning Crisis Into Change

Back in Vridi Akobrakré, the mother dips her children’s hands into treated water and watches volunteers continue their rounds. For families affected by the Abidjan cholera outbreak, clean water remains fragile. But the crisis has sparked meaningful action. Community volunteers are now trained to monitor symptoms, treat contaminated water and educate their neighbors on proper hygiene.

NGOs continue to distribute chlorine tablets, hygiene kits and set up hand-washing stations in schools and markets. If governments and international partners invest in sanitation, infrastructure and poverty reduction, these efforts can become permanent. Safe water systems, drainage improvements and community-led education programs could protect residents from future outbreaks.

What began as a tragedy is turning into a blueprint for resilience, showing that even the most vulnerable communities can lead the way when crisis meets coordinated action.

The Last Mile Against River Blindness in Cameroon

river blindness incameroonIn the rugged highlands of western Cameroon, a silent threat loomed for decades: Onchocerciasis or “river blindness.” Transmitted by the bite of blackflies breeding in fast-flowing rivers, the disease causes severe itching, skin changes and, in its most advanced form, irreversible blindness. For communities living along the valleys of the Meme and Mbam rivers, onchocerciasis did not just affect health; it hampered schooling, work and development in already impoverished areas.

Background

Cameroon has long been an endemic country for onchocerciasis. Indeed, a geospatial modelling study of Africa and Yemen estimated that, as of 2018, national-level infection prevalence in Cameroon exceeded 5% and in some focal regions was much higher.

In response, Cameroon launched community-directed treatment with ivermectin in 1996 under the World Health Organization’s African Programme for Onchocerciasis Control. After APOC ended in 2015, the country continued elimination activities through the WHO’s Expanded Special Project for Elimination of Neglected Tropical Diseases (ESPEN), which now coordinates regional support.

Mass Drug Administration

At the heart of Cameroon’s strategy has been annual mass drug administration of ivermectin delivered through community-directed treatment. Over 15 years of campaigns in several districts have sharply reduced infection levels. In the Tombel Health District, for instance, after 15 consecutive years of treatment, microfilaria prevalence fell to 1.5% and nodule prevalence to 6%, indicating progress but not full interruption of transmission
Yet, remote mountain villages present persistent challenges. A 2024 study along the Cameroon–Chad border noted that onchocerciasis transmission remains ongoing despite decades of CDTI.

Localised vector habitats, seasonal migration of workers, and gaps in treatment coverage are among the underlying factors. A detailed study in the Meme River Basin highlighted how poverty, farming occupations, housing conditions and limited health seeking behaviour all hamper elimination efforts.

Community-Directed Distributors

Community health volunteers, called community-directed distributors (CDDs), carry the burden of delivering ivermectin and tracking treatments in hardscrabble terrain. But their efforts are constrained by low motivation, logistical bottlenecks and limited training. A qualitative study in three rural districts of Cameroon found that inadequate numbers of CDDs and weak understanding of the disease among health staff hamper progress.

Despite these challenges, when coverage is high and sustained, the health benefits are profound. People treated with ivermectin experience relief from itching, healing of skin lesions and prevention of visual impairment, according to the World Health Organization (WHO). In Cameroon’s Meme River Basin, researchers also found that annual community-directed treatment improved productivity and reduced stigma around the disease.

The Future

Progress in Cameroon against river blindness shows how persistence pays off. National health authorities continue annual community-directed ivermectin campaigns with support from the WHO’s Expanded Special Project for Elimination of Neglected Tropical Diseases (ESPEN). The country also participates in regional cross-border monitoring with Chad and Nigeria to track transmission and share data.

According to the WHO’s ESPEN program, several health districts in Cameroon have already transitioned to post-treatment surveillance after interrupting transmission, marking key milestones toward national elimination.

Healing the River: Schistosomiasis in São Tomé and Príncipe

Fighting Schistosomiasis in São Tomé and PríncipeSchistosomiasis or bilharzia thrives where people lack safe water and sanitation. Schistosomiasis remains endemic in São Tomé and Príncipe, primarily caused by Schistosoma intercalatum. The World Health Organization (WHO) classifies the country as requiring preventive chemotherapy, indicating ongoing transmission. Despite multiple rounds of mass drug administration, the disease persists in certain communities, particularly near streams and rice fields, where children remain at risk. Ongoing surveillance is essential to monitor and address localized transmission hotspots.

A Low-Level but Stubborn Threat

Recent studies confirm that São Tomé and Príncipe maintains a low but persistent level of schistosomiasis transmission, primarily caused by Schistosoma intercalatum. According to research published in PLOS Neglected Tropical Diseases in 2023, national prevalence remains low following repeated rounds of mass drug administration and health education campaigns. Ongoing surveillance continues to identify limited transmission in certain communities, underscoring the need for sustained control measures under World Health Organization guidance.

Momentum Since 2014

After a nationwide mapping survey in 2014, the Ministry of Health launched preventive chemotherapy with praziquantel in schools. In 2015 alone, more than 31,000 school-age children received treatment—an essential step to cut infections and protect those most at risk. Continued surveillance has turned up only sporadic cases, including a rare neuroschistosomiasis report in 2020, underscoring why vigilance still matters even as prevalence drops.

A 2024 Milestone: Halting Mass Drug Administration

Regional partners now point to a major achievement. The WHO Africa region’s ESPEN program reported in its 2024 annual review that São Tomé and Príncipe halted mass drug administration (MDA) in all endemic implementation units, marking a key waypoint toward elimination. ESPEN’s 2025 data updates also list STP among countries that did not conduct MDA in 2024, consistent with a transition from blanket treatment to targeted surveillance and response.

Water, Sanitation and Hygiene: The Long Game

Treatment alone cannot finish the job. Lasting gains depend on safe water, sanitation and hygiene (WASH) so people aren’t re-exposed to rivers and irrigation canals. UNICEF reports recent WASH actions in STP, including strengthening handwashing behaviours and coordinating a multisectoral WASH platform—efforts that protect families from schistosomiasis and other infections. Global JMP updates from WHO/UNICEF show why this matters: many health facilities and households worldwide still lack basic WASH services, a gap that sustains NTD transmission.

What’s Needed Next

São Tomé and Príncipe continue national efforts aligned with World Health Organization (WHO) guidance to control schistosomiasis. Current work includes post–mass drug administration monitoring, integrating surveillance into primary health care and coordinating with education and water agencies to sustain prevention gains. The Ministry of Health, with support from WHO and international partners, maintains praziquantel distribution in areas where transmission remains and tracks infection data to guide control strategies. These ongoing initiatives reflect the country’s commitment to meeting the WHO’s 2030 targets for neglected tropical diseases.

Why it Matters

Eliminating schistosomiasis saves children from anaemia, abdominal pain and missed classes, and it strengthens primary health care. With MDA paused and WASH investments growing, São Tomé and Príncipe has a real shot at stopping transmission. Sustained funding for surveillance and water infrastructure can help the islands turn a quiet success into a permanent victory.

Diseases Impacting Chile

Diseases Impacting ChileKnown for its long coastline and diverse landscapes, Chile has made significant strides in public health, with an average life expectancy of 81 and continued progress in reducing infant mortality. However, the nation continues to face public health challenges. These include a difficult COVID-19 response, high numbers of cancer deaths and ongoing problems with cardiovascular disease. Here is more information about the diseases impacting Chile and efforts to address them.

Cancer Progress

In recent years, cancer has rivaled cardiovascular disease for the title of leading cause of death in Chile, with 31,440 reported cancer-related deaths in 2022. In response to cancer being one of the most persistent diseases impacting Chile, the government has implemented multiple policies to fight the disease. The government passed laws to lower tobacco use, increase the number of HPV vaccines and facilitate more cancer research and clinical trials within the country.

In 2018, Chile implemented a national cancer plan. The plan focuses on shortcomings in prevention, diagnosis and treatment for patients across the country. Officials saw success with the formation of a national cancer registry and the existing tumor banks, with one example being roughly 700,000 cholecystectomies being performed since the start of the plan.

Cardiovascular Disease Concerns

Heart disease remains one of the leading causes of death in Chile, at around 25% of all deaths. According to the World Health Organization (WHO), this number was 33,504 in 2023 – an increase in deaths from 2019. Significant risk factors like hypertension, which affects nearly one in four adults in the country, are often unknown to patients and lead to an increased risk for Cardiovascular Disease (CVD). 

The Chilean government has embarked on a mission to increase awareness of hypertension and CVD as a whole. In 2013, the country partnered with the Pan-American Health Organization (PAHO) and the United States’ Centers for Disease Control and Prevention. Across the greater South American region, over three million people have received treatment for hypertension as a result of these partnerships. Concrete successes include the creation of public hypertension clinics, expansion of health coverage in the country and increased data collection to ensure patients are identified before cardiovascular disease can develop.

COVID-19 Difficulties

Chile never established a national lockdown, leading quarantine guidelines to be inconsistent in different localities. With more than 5 million total cases and more than 64,000 deaths, Chile was one of the most affected nations in South America. As recently as 2022, the country saw 13,433 COVID-19 deaths, despite having a vaccination rate of 94.62%. 

Although COVID still poses a risk, Chile has demonstrated its ability to mobilize quickly when it comes to vaccinations. The success of vaccine distribution, combined with low vaccine skepticism in the country, means that Chile is equipped to respond more effectively to the next potential pandemic.

Looking Ahead

Chile’s proactive public health policies and investment in health care infrastructure offer a model for other developing nations. The few diseases impacting Chile still have a grip on the population, with preventable deaths in cancer and cardiovascular disease making up more than 50% of deaths in the country. However, Chile has reasons to be optimistic, with progress being made each year when it comes to infrastructure and research in combating these issues.

COPD Underdiagnosis in Latin America: Challenges and Solutions

COPD Underdiagnosis in Latin AmericaThe PLATINO and PUMA studies from 2002 and 2016 outlined the rate of Chronic Obstructive Pulmonary Disease (COPD) underdiagnosis in Latin America. The data highlighted the importance of early intervention in minimizing the economic and social fallout associated with this respiratory illness.

COPD is caused by damage to the lungs. It can be a consequence of smoking or exposure to air pollutants from biomass fuels. According to the World Health Organization (WHO), the overwhelming majority of deaths of people aged 70 and younger from COPD take place in low- and middle-income nations.

Who Is at Risk?

In Puno, Peru, on the shore of Lake Titicaca, women’s risk of developing respiratory issues due to daily use of biomass fuels is 55%. In Colombia, older men who smoked or were exposed to wood smoke for more than 10 years were more likely to develop COPD. The findings of the 2016 PUMA study, which focused on primary care in Argentina, Colombia, Venezuela and Paraguay, revealed underdiagnosis of COPD in more than 70% of cases. The most affected group included younger men with low educational levels and no prior testing.

Consequences of COPD Underdiagnosis in Latin America

The burden created by the underdiagnosis of COPD in Latin American countries can turn into an even heavier burden that those already struggling with poverty cannot afford:

  • Productivity and work gaps decrease the earning power of people affected and their employers, placing most of the economic burden on the families of the sick.
  • A person whose COPD is more severe due to a lack of early treatment can expect higher health expenses due to the need for hospitalization. In Brazil, the cost of treatment rose from $5,891 in 2010 to $13,181 in 2015.
  • The rate of in-hospital mortality due to COPD in Mexico, Brazil and Argentina continued to rise significantly through the ’80s and ’90s. However, in Brazil, the mortality rate decreased by more than 25% from 2000 to 2019 thanks to local efforts.

The Challenges

In a survey by Vital Strategies and Umane, up to 62.3% of Brazilians did not seek medical attention due to several reasons. The surveyees stated long wait times, difficulties accessing specialists or underestimating the health issue. Up to 40.5% of those who did attempt to visit a doctor could not, due to extensive waiting times, lack of available doctors or proper equipment.

However, starting in 2024, the Breathe Well South America program has a plan to investigate access to primary care for people with COPD. It is being funded by the National Institute for Health and Care Research (NIHR). It’s driven by the work of the Institute for Clinical Effectiveness and Health Policy (IECS) in Argentina and several international universities.

Diagnostic Tools

Spirometers are a vital tool for the diagnosis of COPD. The test measures airflow and volume. In Latin America, it is often underused by primary care providers because of limited access to spirometers, short appointment windows and insufficient training to perform and interpret tests.

Throughout 2022 and 2023, the Brazilian Ministry of Health, in conjunction with the Hospital das Clínicas of the Federal University of Minas Gerais, began putting into place the Telespirometry System Brazil (TS-BR). The initiative aims to provide training and spirometers to specialists. As of 2024, 147 municipalities had participated in the program.

Pharmaceutical giant AstraZeneca launched Smart Spiros in Panama to improve the rate of diagnosis of COPD. Around 7,500 tests are expected to be performed by the end of 2025, which could help diagnose nearly 50% of COPD cases.

Increasing Awareness

The survey by Vital Strategies discovered that 34.6% of Brazilians questioned avoided seeking care because they assumed their health issue wasn’t serious enough to merit a visit. To combat this, World COPD Day takes place worldwide on the third Wednesday in November. It encourages health organizations to educate people about symptoms and possible treatments regularly.

In 2017, Paraguay’s Health Ministry dedicated an entire week to training, education and testing patients. This work is important because early diagnosis is crucial to preventing exacerbations that can result in costly, lengthy hospital stays.

From Underdiagnosis to Action

As of 2024, COPD was the fourth-leading cause of death globally. COPD underdiagnosis in Latin America has been a major issue that national and international organizations are working to quantify and resolve. For people living in poverty, illness and loss of income can become a crippling situation that further diminishes their earning capacity or entirely prevents them from earning a livelihood.

Despite challenges, such as a lack of education, spirometers and trained professionals, universities, international organizations and governments have come together to put into motion programs that bring much-needed solutions to the public.

Fighting the Silent Killer: Hypertension in Sub-Saharan Africa

Hypertension in Sub-Saharan AfricaHypertension, often called the silent killer, is surging across sub-Saharan Africa as cities expand and diets change. The World Health Organization (WHO) says more than one-third of adults in the region live with high blood pressure. Yet, many do not know they have it until they suffer a heart attack, stroke or kidney failure.

Unlike infectious diseases with obvious symptoms, hypertension can go undetected for years. Rural clinics may be miles away and often lack reliable blood pressure cuffs. Even in cities, routine screenings are rare outside hospitals. Poverty deepens the problem.

Many patients skip checkups because of travel costs or lost wages and medication can be hard to find or too expensive.

Community Health Workers Take the Lead

Governments and aid groups are training community health workers to screen residents where they live. In Kenya and Ghana, mobile teams set up at markets and churches to check blood pressure for free. When they discover hypertension in an individual, health workers give lifestyle advice and connect patients to inexpensive generic drugs.

These programs are low-cost and easy to expand, often costing only a few dollars per patient each year.

Medicine matters, but prevention depends on wider change. Public campaigns urge people to cut salt, eat more fruits and vegetables and exercise regularly. In Tanzania, radio programs and text-message reminders promote healthier cooking and daily walks. Urban planners in Nigeria and South Africa are adding walking paths and parks to make physical activity safer and easier.

Partnerships and Policy Momentum

The WHO’s HEARTS Initiative has been deployed in several low- and middle-income countries to standardize hypertension care protocols and strengthen primary care delivery systems. Similarly, regional bodies such as the Pan African Society of Cardiology (PASCAR) have collaborated with the WHO to produce the “Roadmap to Achieve 25% Hypertension Control in Africa by 2025,” guiding national hypertension policies.

National governments have adopted task-sharing and guideline frameworks under pressure from global advocacy groups. In Africa, the Innovative Epidemiology and a Vibrant Ecosystem (ACHIEVE) strategy outlines 10 strategic actions for integrating hypertension control into health systems policy. Furthermore, donor agencies and international NGOs, including Resolve to Save Lives, support the procurement of affordable medications, provide training and provide technical assistance to governments launching hypertension control programs.

Within Africa, the Centers for Disease Control’s (CDC) strategic plans emphasize strengthening partnerships, workforce development and institutional coordination across member states. These efforts aim to embed noncommunicable disease (NCD) control—including hypertension—into broader health systems.

A Vital Step Toward Stronger Health Systems

Controlling hypertension in sub-Saharan Africa strengthens health services overall. Routine blood pressure checks create chances to spot diabetes and other chronic diseases. Reliable supply chains for hypertension drugs improve access to other essential medicines. By fighting a silent but deadly disease, sub-Saharan Africa can prevent countless premature deaths and build a healthier, more productive population. This shows that tackling chronic illness is as important to development as battling infectious disease.

Dr. Fairlie and the Breakthrough in the Fight Against TB

Dr. FairlieTuberculosis (TB) is a contagious disease that generally affects the lungs, but also affects other parts of the body. Prevention of TB involves screening those at high risk, treatment of cases and early detection. TB is the leading cause of death worldwide despite the bacillus Calmette-Guérin (BCG) vaccine. However, people who are already exposed to the disease are required to go through multiple antibiotic treatments over a long period of time.

More than Just Numbers

In 2023, 1.3 million people died from TB. In 2022, 10.6 million people fell ill with TB. This is a disease that has claimed countless lives and will not stop unless someone discovers a proper vaccine, and soon. As more time passes, TB becomes more resistant to the vaccines that doctors already use.

This large death toll from TB is not only due to infection, it is also due in part to the large population living with HIV as well. Of those 1.3 million who died of TB, 167,000 of those people were diagnosed with HIV. TB is also the leading cause of death among people with HIV and a major cause of antimicrobial resistance-related deaths.

Progress

Preventing the TB disease, rather than the infection, has been the main target for vaccine development. Development of an effective TB vaccine is a top global priority that many scientists have been working on for decades.

It is because of this that the paediatrician and researcher in Johannesburg, South Africa, Dr Lee Fairlie, has made it her mission to help the people in need. She has seen more than her fair share of TB-related deaths over the course of her career, mostly because of the large population of those with HIV that live in South Africa.

Though the search for a TB vaccine has been slow, researchers are making progress nonetheless. Dr. Fairlie has made it her mission not to give up, and now, she and her colleagues may be on the verge of a breakthrough.

A New Vaccine and Hope for the Future

Her team is one of the sites conducting a landmark M72/AS01E TB vaccine trial, with the help of Gates Medical Research Institute and funded by the Gates Foundation and Wellcome, which includes sites across four African countries (including South Africa) and Indonesia. At first, GSK developed it in collaboration from Aeras and the International AIDS Vaccine Initiative. M72 could possibly be the first new TB vaccine in more than a century and the first-ever to help protect adults and adolescents from the disease.

While the clinical trial is still in its early stages, M72’s initial reports have filled the team with hope. M72 reportedly had a near 50% efficacy after three years in preventing TB-infected adults from developing active disease, which would make them both sick and contagious to others.

While the results are years away, Dr. Fairlie is hopeful for the future, as this could be a step further towards a world without TB.

Fighting Hunger and Cholera in Sudan

Cholera in SudanSudan is caught in the middle of a dual emergency. A devastating cholera epidemic and widespread famine have left millions of people facing preventable illness and hunger. Ongoing conflict has only deepened the crisis, destroying infrastructure, displacing families and cutting off humanitarian access. Yet even in this bleak picture, targeted global efforts are showing that solutions exist; if they can be scaled and sustained.

The Scale of the Crisis

Since 2024, Sudan has endured one of its worst cholera epidemics in decades, with hundreds of thousands of suspected cases reported and thousands of deaths. At the same time, more than 25 million people are now acutely food insecure, with famine conditions confirmed in parts of Darfur.  The war between Sudan’s military and the Rapid Support Forces has turned health into a casualty, destroying water systems and hospitals and blocking supply lines. Without outside help, this fight against cholera and hunger could possibly wipe out half of Sudan’s population.

Emergency Responses on the Ground

Despite these barriers, humanitarian organizations are working on the frontlines to contain the damage. The World Health Organization (WHO) and Médecins Sans Frontières (MSF) are leading cholera vaccination campaigns, distributing rapid diagnostic kits and deploying mobile health clinics into hard-to-reach areas. These global efforts are critical not only for treating current outbreaks but also for limiting future spread and helping rebuild Sudan.

Meanwhile, the World Food Program (WFP) has stepped in to confront hunger and malnutrition. WFP is providing food aid, therapeutic feeding for children, and cash assistance where local markets still function, ensuring that the most vulnerable can survive through the worst of the shortages. Local NGOs add another layer of support, such as SUDO, repairing broken water points and working with communities to restore sanitation systems.

Building Long-Term Resilience

Sudan’s health system should be able to withstand future shocks. That means training local health workers, strengthening laboratory capacity and investing in disease surveillance to enable early detection of outbreaks like cholera. International strategies like the WHO’s ‘Global Cholera Roadmap 2030’ provide a framework for reducing cholera deaths by 90% worldwide. Applying this roadmap in Sudan, through water and sanitation upgrades, vaccination drives and better outbreak detection, could turn the tide not just in this crisis, but for decades to come and help Sudan fully rebuild itself.

The Role of Funding and Coordination

The financial dimension is also critical. The WFP warns that humanitarian operations in Sudan remain severely underfunded, with hundreds of millions of dollars still needed this year. Donor countries and development banks will need to align funding with coordinated strategies, ensuring resources go where they are most necessary. These small global efforts could lead to a big step to help Sudan rebuild itself by fighting cholera and hunger!

A Path Forward

Sudan’s crisis is far from over, but the path forward is clearer than it may appear. By protecting humanitarian access, expanding vaccination & food aid and investing in long-term health resilience, global actors can help Sudan move from mere survival toward recovery. The country’s people have endured staggering loss; what they need now is a consistent international partnership that delivers not just aid, but the tools to rebuild their health and dignity.

Taking Action Against Yellow Fever in Colombia

Yellow Fever in ColumbiaAfter the mysterious deaths of three monkeys of different species in Putumayo, Colombia, health teams quickly determined the cause. They identified that the deaths were not random or coincidental, but the beginning of what could have been a yellow fever outbreak in Colombia. It is a highly contagious virus mainly transmitted by mosquito bites.

However, it can be prevented by vaccines, which are relatively affordable and easily accessible. Nonetheless, depending on the region, it can be harder to access or afford. In 2025, five countries reported an increasing presence of yellow fever. In Colombia (as of June 28, 2025), there have been 114 confirmed human yellow fever cases, 49 confirmed deaths and case fatality rate of 43%.

The Pan-American Health Organization (PAHO) offered training to health teams through the PROTECT initiative in Colombia. It educated health workers on taking preventative measures quickly and efficiently against outbreaks of viral diseases such as yellow fever.

Education From Health Professionals

Following the deaths of the monkeys, several immediate preventative measures were taken. These included vaccinating environmental workers, conducting entomological studies and analyzing the affected area. Due to the training offered by PAHO, health teams were taught how to take samples from wildlife safely and the importance of integrated surveillance.

Integrated surveillance showed health workers the importance of monitoring primates and mosquitoes in the area and shared many tools to take preventative action and control outbreaks. Due to strong surveillance of the area, Colombian professionals were able to identify the presence of yellow fever in Putumayo, Colombia and control further spread of the virus.

Maintaining high vaccination levels and continued wildlife surveillance will help catch future outbreaks before they become too severe. Colombia has issued regulations and laws to help contain the spread of yellow fever and increase preparedness for future situations where swift action is needed.

PAHO has urged countries to “maintain active surveillance, vaccinate at-risk populations and ensure rapid responses to early warning signs — such as unexplained monkey deaths.” This is extremely important because our health depends on the health of our environment and the wildlife inside it. Monkeys are extremely similar to humans, so we won’t be far behind if they are affected.

The Future of PAHO’s Health Initiative

PAHO has made guidance documents publicly available on the regional level, which include instructions on safe sample collection, guidelines for managing control endeavors and maps of high-risk areas. It continues to conduct in-person training on surveillance and entomology of yellow fever for vulnerable countries.

Colombia has also issued circulars that establish transitional measures for yellow fever vaccinations. The criteria of these letters extend from ages 9 months to 59 years of age. The public health risk of yellow fever is extremely high.

However, with these measures implemented by PAHO/WHO, such as increasing vaccination levels, people have been successfully learning to save lives and contain outbreaks of yellow fever in Colombia.

All About Tungiasis in Sub-Saharan Africa: What, Where and How

All About Tungiasis in Sub-Saharan Africa: What, Where and How Tungiasis is a neglected tropical disease (NTD), meaning it does not receive adequate attention.  It is most prevalent among those living in poverty in the Caribbean, South America and the sub-Saharan region of Africa. Despite this fact, Tungiasis continues to go unaddressed in global public health agendas. Tungiasis does not get much coverage in academic circles, by community health care practitioners, public health experts, decision makers, funding organizations and pharmaceutical companies. No country, particularly in the sub-Saharan region, knows its disease burden regarding Tungiasis, which is a challenge in addressing the problem.

The What

Tungiasis is a skin disease caused by female sand fleas (Tunga penetrans), commonly called jiggers. It is a zoonosis, meaning it can be transmitted between humans and animals, particularly domestic animals such as dogs, cats and pigs. The disease occurs when the female flea burrows into the skin. The most affected areas of the human body are the feet, but the elbows, hands, knees, genitals, buttocks and periungal areas (fingers or toes) are also sites of infection.

At the acute stage, victims suffer from severe pain, itching, sleep problems, inflammation, swelling, deep fissures, ulcers and abscess development due to bacterial superinfection.  Those who suffer chronically experience protracted pain, deformity, damage to the feet, disability and eventually long-term cognitive impairment. In addition to the physical manifestations of the disease, those with Tungiasis also endure social stigma and isolation.

Tungiasis Prevalence: The Where

The prevalence of Tungiasis in Sub-Saharan Africa varies by location.  The disease primarily affects children and elderly people in every country within the Sub-Saharan region of Africa.  The prevalent rates of infection in each country are as follows: 

  • Ethiopia: 46.5%
  • Cameroon: 44.9%
  • Tanzania: 42.0%
  • Kenya: 37.2%
  • Nigeria: 28.1%
  • Rwanda: 22.7%
  • Uganda: 20.1% 

These rates are averages, but some areas within these countries show higher prevalence. For example, northeastern Uganda recorded a prevalence rate of 62.8%.

Ongoing Efforts: The How

Risk factors for contracting Tungiasis include poverty, poor hygiene, lack of sealed flooring, mud/earthen housing, rearing of domestic animals, and walking barefoot. Home remedies attempted include manual extractions with non-sterile sharp instruments, which cause inflammation, significant pain, bleeding, open wounds and a high risk of bacterial and viral infections. Other methods include the use of motor oil, tobacco, naphthalene, kerosene and hydrogen peroxide. None of these methods is effective, and all are dangerous.

The most recommended treatment for Tungiasis is the use of low-viscosity Dimeticone. It is the most effective and works in mild and severe cases. Another effective treatment is the combination of coconut and neem oil. However, it is not as effective as Dimeticone and requires more application to the affected area.

Innovations for Tropical Disease Elimination (IFOTRODE), a humanitarian organization based in Uganda, carried out a two-year study in the country’s northeast. The study included quarterly detection and treatment efforts. People and animals received treatment with Dimeticone oil, and the team also organized community health promotions through local dialogues. During the study, health workers diagnosed and treated 12,540 cases. As a result, the prevalence of tungiasis in the area dropped from 62.8% to 5.7%. It appears researchers have discovered the formula required to reduce and even possibly eradicate Tungiasis.

Looking Ahead

The success of community-based efforts in Uganda shows that the right tools and attention can dramatically reduce tungiasis. Expanding access to effective treatments like dimeticone, investing in public health education, and strengthening global awareness will help eliminate the disease.
