Neglected killer: kala-azar disease surges in Kenya
For nearly a year, repeated misdiagnoses of the deadly kala-azar disease left 60-year-old Harada Hussein Abdirahman's health deteriorating, as an outbreak in Kenya's arid regions claimed a record number of lives.
Kala-azar is spread by sandflies and is one of the most dangerous neglected tropical diseases, with a fatality rate of 95 percent if untreated, causing fever, weight loss, and enlargement of the spleen and liver.
Cases of kala-azar, also known as visceral leishmaniasis, have spiked in Kenya, from 1,575 in 2024 to 3,577 in 2025, according to the health ministry.
