Leishmaniasis is a vector-borne disease that is transmitted by sandflies and caused by obligate intracellular protozoa of the genus Leishmania. Human infection is caused by about 21 of 30 species that infect mammals. These include the L. donovani complex with 3 species (L. donovani, L. infantum, and... L. chagasi); the L. mexicana complex with 3 main species (L. mexicana, L. amazonensis, and L. venezuelensis); L. tropica; L. major; L. aethiopica; and the subgenus Viannia with 4 main species (L. (V.) braziliensis, L. (V.) guyanensis, L. (V.) panamensis, and L. (V.) peruviana). The different species are morphologically indistinguishable, but they can be differentiated by isoenzyme analysis, molecular methods, or monoclonal antibodies.

Each year, rabies causes approximately 59,000 deaths worldwide. Despite evidence that control of dog rabies through animal vaccination programs and elimination of stray dogs can reduce the incidence of human rabies, dog rabies remains common in many countries and exposure to rabid dogs is still the ...cause of over 90% of human exposures to rabies and of 99% of human rabies deaths worldwide. CDC experts in the Poxvirus and Rabies Branch conduct an annual assessment of individual countries’ rabies status worldwide which considers the presence of wildlife rabies, canine rabies variant (dog rabies), and non-rabies lyssaviruses.
