Humans and monkeys are most popularly affected by the yellow fever virus. Mosquitoes transmit the virus return and forth between monkeys, humans, or both.
Yellow fever caused by when a mosquito bites a human or a monkey affected with yellow fever, the virus goes the mosquito’s blood flow. It circulates before settling in the salivary glands. When the affected mosquito bites another monkey or human, the virus then transmits the host’s blood flow, where it may create illness. This is the actual cause of Yellow Fever.
