- Health & Fitness
The symptoms of yellow fever occur in two stages. The initial symptoms develop three to six days after infection, and can include:
a high temperature (fever)
a headache
nausea or vomiting
muscle pain, including backache
loss of appetite
This stage will usually pass after three to four days and most people will make a full recovery.
However, around 15% of people go on to develop more serious problems, including jaundice (yellowing of the skin and whites of the eyes), kidney failure and bleeding from the mouth, nose, eyes or stomach (causing blood in your vomit and stools).
Up to half of those who experience these symptoms will die.

Symptoms, treatment and spread of yellow fever
The virus that causes yellow fever is passed to humans through the bites of infected mosquitoes. The mosquitoes that spread the infection are usually active and bite during daylight hours, and are found in both urban and rural areas.
Yellow fever can’t be passed directly from person to person through close contact.
