The term Kala-Azar comes from the Persian and means something like "black disease": in this form of leishmaniasis, the skin turns blackish. After an incubation period of three to six months - sometimes only years - the patient experiences flu-like symptoms.
- High fever,
- increasing malaise,
- Swollen glands,
- Bronchitis and
- Upper abdominal pain due to enlargement of the liver and spleen.
The patients lose a lot of weight, the organ attack by the parasites inflates the stomach.
How is the disease transmitted?
All Leishmanioses are triggered by single-celled parasites that are transmitted by sand or butterfly mosquitoes. The parasites usually live in rodents, dogs and foxes. From there, they enter the intestine of the insect through a first mosquito bite, where they multiply and develop. In a second mosquito bite, the parasites are then transferred to humans. There is no vaccine against leishmaniasis. The only protection are garments with long arms and legs, as well as a consistent, consistent mosquito repellent.
