Causes of Yellow Fever

Yellow fever is caused by the yellow fever virus (or flavivirus), which is spread through bites from infected mosquitos. When mosquitoes bite a human or a monkey carrying the virus, they get infected. The sickness is not contagious.

Mosquitoes thrive in tropical rainforests, humid and semi-humid climates, and near sources of still water.

Increased interaction between humans and infected mosquitoes can result in small-scale outbreaks, especially in places where people have not been vaccinated against yellow fever.

Prevention 

Yellow fever can only be prevented through vaccination. Yellow fever vaccination is given as a single dose. It contains a live, weakened virus that helps your body build immunity.

Yellow fever vaccine 17D is one of the most effective vaccinations ever developed. A single shot can last a lifetime.
