Yellow fever passes through the yellow fever virus, which is transmitted by mosquito bites. The virus called “Yellow fever virus” is also known to be as “Flavivirus”. Yellow fever cannot be spread from one person to the other person. It is caused due to a mosquito bite called Aedes aegypti.
These types of mosquitoes are found near human habitations, and it is expected that these mosquitoes particularly breed in fresh and clean water.
Most of the time, humans and monkeys are affected by yellow fever. The flavivirus, which is known to be the Yellow fever virus, is expected to be endemic among monkeys that reside in the forest and jungles of Africa and America.
When a mosquito bites the infected monkeys, it acts as a transmitting agent and spreads it to people, thereby causing yellow fever to the person.
Risk of Yellow fever
People who reside in densely populated areas with mosquitoes and the people who have not been vaccinated are at a huge risk of yellow fever infection. A person who is around the region of the yellow virus-prone area has a higher chance of getting affected by this dreadful virus.
Therefore, before visiting places where the infection of yellow fever is high, vaccination is preferred to those people.
People can administer the yellow fever vaccine before two weeks going to places.
