The Union of Comoros Nears a Major Health Milestone: The End of Lymphatic Filariasis

Comoros - In an unprecedented move towards public health advancement, the Union of Comoros stands on the brink of achieving a significant milestone: the elimination of lymphatic filariasis (LF) as a public health problem. This remarkable progress is a direct result of the concerted efforts of various stakeholders, including the pivotal role played by the German Corporation for International Cooperation (GIZ) as a donor and funder in association with ESPEN.

Recent Transmission Assessment Surveys (TAS) conducted across the islands of Ndzouani, Mwali, and Ngazidja have shown encouraging results. In the sentinel site of Ntsaouéni, a prevalence of only 1.6% was observed, while in other sites like Mohoro, Mkazi, and Ntsoralé, the prevalence was remarkably low or non-existent. Among surveyed students aged 6-7 years, the prevalence rates were as low as 0.12% in Ndzouani, 0.13% in Mwali, and 0.06% in Ngazidja. These figures, significantly lower than the thresholds set by WHO, indicate a successful interruption of LF transmission, a feat that seemed daunting just a few years ago.

The road to this success was paved with challenges, including delays in acquiring diagnostic tests (Filarial Test Strip) and logistical constraints. However, the robust collaboration between the health and education sectors, effective treatment protocols, and the strategic support from GIZ and ESPEN turned these challenges into stepping stones. GIZ has been instrumental in this journey, providing not just financial support for the transmission assessment surveys but also facilitating capacity building of national staff and expert technical assistance. Their support, coupled with the strategic guidance of ESPEN, has been vital in enhancing the logistical capabilities of the Disease Control Directorate and ensuring the efficient distribution of resources.

As the Union of Comoros prepares its dossier for the elimination of LF by 2024, the role of these international partners cannot be overstated. The meticulous planning and execution of TAS 2 in Ngazidja in 2025 and TAS 3 in 2027, based on the satisfactory results of TAS 2, are testaments to the effective strategies and collaborations in place. The Union of Comoros, with the unwavering support of GIZ and ESPEN, serves as a beacon of hope and a model for other nations striving to eliminate neglected tropical diseases. The journey towards LF elimination in Comoros is not just a public health victory but also a shining example of what can be achieved through country commitment and leadership, and global partnership.
