"Yellow fever" is caused by the Flavivirus, a virus which is spread by the Aedes aegypti mosquito. humans and monkeys are most commonly affected. When one of these mosquitoes bites someone who is already infected with yellow fever, the virus goes into the mosquito's bloodstream and moves around its body before it settles in the mosquito's salivary glands. Because it now resides in the salivary glands, when this mosquito bites another human or monkey, the virus then goes into that person or monkey's bloodstream, causing Yellow fever.

You prevent yellow fever by preventing people from being bitten by an infected mosquito. You can do this to a degree by use of mosquito netting, mosquito repellent, etc. Historically, it was most effectively done by eliminating mosquito breeding ponds, thus reducing or eliminating the population of mosquitoes available to be infected. An effective vaccine against yellow fever is also available.
