What is yellow fever?

Yellow fever is caused by a virus which attacks the liver. Symptoms include fever, jaundice and vomiting. Damage to the liver cells causes jaundice which gives the skin a yellow colour and hence the name. The virus is spread by mosquitoes. There is no cure and so prevention is very important. It was Walter Reed who discovered the cause of yellow fever in 1900 and its mode of transmission.
