The fight against neglected tropical diseases (NTDs) in Africa is gaining ground, with Uganda and Equatorial Guinea leading the battle against human African trypanosomiasis (HAT), better known as sleeping sickness. Once a pervasive threat to millions of lives, these countries have successfully eradicated sleeping sickness as a public health problem. This achievement highlights the effectiveness of concerted public health efforts and sets a precedent for other African nations aiming to tackle similar health challenges.
Sleeping Sickness: A Persistent Public Health Threat
Human African trypanosomiasis is a parasitic disease transmitted by the tsetse fly. It progresses in two forms: Trypanosoma gambiense, which causes the majority of cases, and Trypanosoma rhodesiense, which is more acute. If untreated, the disease can lead to coma and death. For decades, sleeping sickness was a major health burden in sub-Saharan Africa, particularly in remote rural areas where access to healthcare was limited. At its peak in the early 2000s, over 26,000 cases were reported annually, threatening the livelihoods and health of millions, according to a report by HealthCare Middle East & Africa.

However, thanks to strides in diagnostics, treatment, and vector control, the global incidence of the disease has dropped by more than 95%. Between 2001 and 2021, the number of cases fell from 26,095 to just 750, according to HealthCare Middle East & Africa. This reduction can be attributed to advances in treatment, particularly the development of less toxic drugs, as well as focused efforts to control tsetse fly populations, which transmit the disease.
Uganda’s Success in Eliminating Sleeping Sickness
In 2022, Uganda was officially recognised by the World Health Organization (WHO) for eliminating the Gambiense form of sleeping sickness as a public health issue. The country’s success story began in the early 2000s when Uganda’s government partnered with international organisations to launch comprehensive surveillance and control programmes in the West Nile region, one of the most affected areas. Intensive efforts to monitor at-risk populations, combined with mass screenings, allowed Uganda to detect and treat cases early, preventing large-scale outbreaks, according to The Independent Uganda.
The Ugandan government’s approach also included large-scale tsetse fly control measures and education campaigns to raise awareness in endemic areas. These efforts, together with rapid diagnostic tools and effective treatments, ensured that the disease was successfully contained. This triumph demonstrates the power of government-led initiatives, supported by international partnerships, in tackling major public health challenges.
Equatorial Guinea’s Battle Against Sleeping Sickness
Equatorial Guinea’s achievement in eradicating sleeping sickness is equally impressive. In 2020, the WHO officially validated the country’s efforts to eliminate the Gambiense form of the disease. This accomplishment was the result of a multifaceted approach spearheaded by the country’s Ministry of Health, which focused on intensive surveillance, proactive screening, and vector control.
Equatorial Guinea’s National Control Programme for Human African Trypanosomiasis (PNCTHA) played a huge role in this success. The programme integrated modern diagnostic techniques and treatments into the country’s healthcare system, ensuring that cases were detected and treated swiftly. Moreover, rigorous control measures targeting tsetse flies helped reduce transmission risk, while continuous monitoring ensured that no new cases went unnoticed, according to HealthCare Middle East & Africa.
The Role of International Collaboration
Both Uganda and Equatorial Guinea’s success stories underline the critical role that international cooperation plays in combating sleeping sickness. The WHO and other global health organisations have provided technical support, funding, and research to strengthen local healthcare systems and bolster eradication efforts. According to a report by the London School of Tropical Medicine and Hygiene (LSTM), the Trypa-NO! programme has been instrumental in advancing diagnostics and treatments, with continued funding ensuring that efforts to eliminate the disease remain sustainable.
A Model for Other African Countries
The elimination of sleeping sickness in Uganda and Equatorial Guinea provides a roadmap for other African nations still grappling with this disease. Early detection, strong surveillance systems, and community engagement can accelerate progress in other countries toward eliminating sleeping sickness as a public health threat.
As part of the WHO’s 2030 roadmap for the elimination of neglected tropical diseases, these countries are setting an example and also sending a powerful message to the world: with the right combination of resources, political will, and global partnerships, even the most entrenched public health issues can be overcome.
