Yellow fever Infection Method

Yellow fever is caused by yellow fever virus, it is a potentially lethal disease spread by infected mosquitoes. The virus is endemic in tropical areas of Africa and Central and South America.

Large epidemics of yellow fever occur when infected people introduce the virus into heavily populated areas with high mosquito density and where most people have little or no immunity, due to lack of vaccination. In these conditions, infected mosquitoes of the Aedes aegypti specie transmit the virus from person to person.

The symptoms of Yellow Fever

Once contracted, the yellow fever virus incubates in the body for 3 to 6 days. The symptoms of Yellow Fever emerge in three stages:

  • Infection : fever, headache, jaundice, muscle pain, nausea, vomiting and fatigue.
  • Remission : The symptoms disappear
  • Intoxication : Problems with heart, liver, and kidneys
    Severe cases of Yellow Fever can be fatal.

A small proportion of patients who contract the virus develop severe symptoms and approximately half of those die within 7 to 10 days.
