| Abstract | Leishmaniases are a group of diseases under the category of neglected tropical diseases targeted for global elimination. However, they continue to pose major clinical and public health problems, especially among those living in poor socioeconomic conditions. Here, we summarize leishmaniasis elimination efforts in Bhutan. Between 1994 and 2022, Bhutan recorded 54 cases of leishmaniasis across 14 of its 20 districts. There are seven species of Phlebotomus and three species of Sergentomyia sand flies documented in the country. At a subnational level, all endemic districts recorded a visceral leishmaniasis annual incidence <1 per 10,000 population, meeting the regional elimination targets. Serological testing with ELISA and molecular testing with polymerase chain reaction were established at the Royal Center for Disease Control in 2022. A leishmaniasis prevention and management guideline was adopted in 2023 to aid clinicians in diagnosis and management. Active and passive case surveillance was integrated with the national infectious disease early warning and response system. Risk-based entomological surveillance and control have also been prioritized. Climate change may play a major role in rendering districts in the temperate zone favorable for vector proliferation. The country's medical university introduced a diploma course in medical entomology in 2023 to augment the human resources needed for vector surveillance efforts. However, leishmaniasis elimination lacks dedicated programmatic management amid competing priorities for resources against other infectious diseases. Leishmaniasis elimination requires a targeted and programmatic approach in Bhutan, including cross-border collaborative efforts with neighboring Indian states. Bhutan remains highly committed to achieving leishmaniasis elimination targets. |
