What are the limitations of the aldehyde test for Kala Azar?
False-positive results may be caused due to conditions like malaria. Additionally, assay interferences may be caused by the presence of viscous material or glycerol in the sample, as well as co-existing immunosuppressant conditions such as HIV
How is leishmaniasis transmitted?
Leishmaniasis is transmitted by the phlebotomine sand fly when it bites an individual or animal that is already infected, and subsequently bites another person, injecting them with the Leishmania parasite.
