What are its risk factors Of Black Fever
Leishmania parasites, which cause kala azar, are actually transmitted through the bites of infected female phlebotomine sandflies. According to the World Health Organization, its main risk factors include:
1. Socioeconomic conditions
Poverty can increase the risk of kala azar as bad sanitary conditions may increase sandfly breeding and resting sites. Sandflies are attracted to crowded locations.
Consuming diets that are lacking protein, iron, vitamin A and zinc increase the risk of kala azar or black fever leading to a full-blown disease.
3. Population mobility
If migration and movement of non-immune people happens into areas with existing transmission cycles, there are high chances of the disease to occur.
4. Climate change
Leishmaniasis is climate-sensitive and changes in temperature, rainfall and humidity can have a direct impact on reservoir hosts and can aid in the developmental cycle.
