How can leishmaniasis be transferred to humans?
Leishmaniasis is primarily transmitted to humans through the bites of infected female phlebotomine sandflies, which are vectors for the Leishmania parasites. When a sandfly bites a human, it injects the parasites into the bloodstream, leading to infection. The disease can also be transmitted through other means, such as blood transfusions, organ transplants, or from mother to child during pregnancy. However, the most common transmission route is through the bites of infected sandflies in endemic regions.
