What is yellow fever?
Yellow fever is caused by a virus infection spread by a bite of an infected mosquito. The mosquito injects the yellow fever virus into the bite.
What are the symptoms of yellow fever?
Symptoms usually occur three to six days after a person is bitten. Many yellow fever infections are mild, but the disease can cause severe, life-threatening illness. Symptoms of severe infection are high fever, chills, headache, muscle aches, vomiting, and backache. After a brief recovery period, the infection can lead to life threatening medical condition with bleeding, kidney and liver dysfunctions. Liver failure causes jaundice (yellowing of the skin and the whites of the eyes), which gives yellow fever its name
Yellow fever has three stages. The first stage leaves a person experiencing headaches, muscle and joint ache, a fever and vomiting. After three to four days the symptoms briefly go away. The second stage, the period of remission, is the stage in which most people recover, but may step into the third stage. During the third stage, multi-organ dysfunction occurs, which can include heart, liver and kidney failure, bleeding and brain disorders, such as seizures or a coma.
