- Epidemiology
- According to the Global Burden of Disease Study
from 2015, the leishmaniases are the third most
important vector-borne disease after malaria and
dengue, with an estimated 1.4 million all-age
disability-adjusted life years (a 3.8% increase
between 2005 and 2015). The leishmaniases are
endemic in more than 90 countries in the tropics,
neotropics, and southern Europe. An estimated 0.7 to
1 million cases are diagnosed each year, with 20,000
to 30,000 deaths. According to the World Health
Organization, over 1 billion people living in endemic
areas are at risk of infection.
