What is leishmaniasis?
Leishmaniasis is a group of diseases caused by various types of Leishmania parasites, transmitted through sand fly bites. It can lead to disfiguring skin ulcers and severe, life-threatening conditions. Leishmania is found in over 90 countries worldwide.
Leishmaniasis is present in:
•Certain parts of Asia.
•Parts of Africa, including tropical regions and North Africa.
•Southern Europe.
•The Middle East.
•Central America.
•South America.
•Some areas of Mexico.
How is leishmaniasis transmitted?
Because many individuals can be infected with Leishmania without showing symptoms, it can be difficult to determine how widespread leishmaniasis is. Leishmania parasites cause leishmaniasis and can live in humans and animals, such as dogs, cats, possums, rodents, and foxes.
Less common ways of transmission include:
•Sharing needles.
•Receiving a blood transfusion.
•Transmission from a pregnant woman to her fetus.
Can humans get leishmaniasis from dogs?
No, humans cannot contract leishmaniasis directly from dogs or other animals. However, dogs can spread the disease to other dogs. Since sand flies can transmit leishmaniasis from dogs to humans, it is important to prevent dogs from becoming infected.
What are the signs and symptoms of leishmaniasis?
The symptoms of leishmaniasis depend on the type of the disease. Cutaneous and mucosal leishmaniasis cause large, slow-healing ulcers. Visceral leishmaniasis leads to general symptoms, such as fever, weight loss, and abdominal swelling.
How can I prevent leishmaniasis?
The most effective way to prevent all forms of leishmaniasis is to avoid sand fly bites, particularly in areas where Leishmania is prevalent.
