Kala azar is one of the most dangerous neglected tropical diseases in the world. It is spread to humans by bites from infected female sand flies and attacks the immune system. While cases of the disease are declining steadily, kala azar-HIV co-infection is fast becoming a serious threat.
After treating over 12,000 kala azar patients in Bihar, northeast India, MSF launched activities to treat people co-infected with kala azar and HIV in 2017. Over 700 people have received treatment since the project opened.
