Is leishmaniasis curable?
Leishmaniasis is a treatable and curable disease, which requires an immunocompetent system because medicines will not get rid of the parasite from the body, thus the risk of relapse if immunosuppression occurs. All patients diagnosed as with visceral leishmaniasis require prompt and complete treatment.

Where do Phlebotomus flies spread leishmaniasis to?
Phlebotomine flies that transmit Leishmania live in the warm tropical and subtropical areas of the world. As climate changes and temperatures shift, tropical diseases are shifting, as well. Health researchers expect human leishmaniasis to follow the spread of Phlebotomus flies into regions of increasing warmth and humidity.
