What Is Yellow Fever?
2. Causes
Aedes aegypti is the species of mosquito responsible for yellow fever, and it can also spread a number of other diseases. The mosquito causes yellow fever by infecting people with the yellow fever virus, which is a type of flavivirus. The virus can have different species as a host, which are usually humans and monkeys.
When a mosquito feeds from an infected host, it too can become infected with the virus. When the mosquito chooses its next meal, it will bite into the blood stream, potentially allowing the virus to enter into its new host. One in the bloodstream, the virus may go on to proliferate and cause problems for its new host.
