Kala-azar

Kala-azar, also called visceral leishmaniasis, is a serious parasitic infection spread by the bite of infected sandflies. It is among the most deadly diseases affecting tropical and subtropical regions. Kala-azar gets its name from the Hindi words “kala” (black) and “azar” (fever/disease). It refers to the darkening of the skin that can occur in some people as the illness progresses, along with prolonged fever. 

Other common symptoms can include weight loss, weakness, and enlargement of the spleen and liver. Poor housing, malnutrition, weak immunity, and living in or traveling to endemic areas can increase the risk of this disease.

Effective treatment is available, often using medicines like amphotericin B or miltefosine. Getting diagnosed early can make treatment simpler and more successful. Completing the full course is important to avoid complications and improve outcomes.
