YELLOW FEVER - Watsons Health

YELLOW FEVER

Yellow fever is a serious viral infection that’s spread by certain types of mosquito. 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, from dusk until dawn, and are found in both urban and rural areas.

The symptoms of yellow fever occur in two stages. The initial symptoms develop three to six days after infection, and can include:

  • fever
  • headache
  • nausea or vomiting
  • muscle pain
  • back pains
  • 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, kidney failure and bleeding from the mouth, nose, eyes or stomach. Up to half of those who experience these symptoms will die.
