A general characteristic of leishmaniasis is given, and the features of the course of infection in immunodeficiency are also presented. In the example of clinical cases, issues featuring diagnostics and treatment of leishmaniasis are reviewed, the mortality rate of which remains quite high. The accession of Crimea to Russia, the high prevalence of HIV infection in the world, as well as the annually increasing tourist flow to endemic countries, require physicians of all specialties to be aware of this disease. HIV patients deserve special attention, there are already a number of reports that people with HIV are diagnosed with visceral leishmaniasis and are at greater risk of infection than the general population.
