Leishmania is found in parts of about 88 countries, primarily in the tropics and subtropics. Approximately 350 million people live in these areas.
Geographic Distribution of Leishmaniasis
Leishmaniasis exhibits a diverse geographic distribution, influenced by environmental factors and the presence of vector sandflies. The settings in which leishmaniasis is found range from rain forests to deserts. Key regions include:
- Central and South America: These regions, particularly areas with tropical rainforests, are endemic for various forms of leishmaniasis.
- West Asia: Desert regions in West Asia also harbor leishmaniasis.
- Other Regions: Leishmaniasis is also found in parts of Africa, the Mediterranean basin, and even some parts of southern Europe.
Key Facts:
- Tropics and Subtropics: The majority of affected countries are located in these regions.
- Vectors: The sandfly vectors thrive in varied environments, contributing to the disease's wide distribution.
- Public Health Concern: Leishmaniasis poses a significant public health challenge in affected regions, impacting millions of people.
Leishmaniasis's distribution highlights the importance of understanding the ecological factors that influence its spread and implementing effective control measures in endemic areas.
