Rest is the usual treatment. However, if you are infected with yellow fever, follow the advice of your doctor.

There are many symptoms of yellow fever. The symptoms vary from person to person and one person may not experience all of the symptoms.

Some of the most common symptoms of yellow fever are:

  • high¬†fever
  • chills
  • headache
  • muscle aches
  • vomiting
  • backache

Symptoms of yellow fever usually appear between 3 and 6 days after being infected by a mosquito.

Yellow fever must be monitored by a doctor. After a brief recovery period, the infection may lead to shock, bleeding, and kidney and liver failure.

Female mosquitoes transmit the virus because they take blood from the bitten victim. Male mosquitoes do not take blood from the victim. After the mosquito ingests the virus, it takes about a week to ten days or so for that mosquito to become infective.

Yellow fever is a viral tropical disease that is spread to humans by infected mosquitoes. The disease is caused by a virus. Most yellow fever infections are mild. However, the disease can cause severe, life-threatening illness. Yellow fever is found only in parts of Africa and South America. Yellow fever has caused large epidemics in Africa and Northern and Southern America.

Yellow fever symptoms include fever, nausea, weakness, back pains and headaches. The disease may fall into remission for a short period, and if untreated, a toxic stage may follow, symptoms that are a more severe version of the initial symtoms and may include vomiting, abdominal pain and fatigue; hemorrhagic events may also occur, including bruising and nosebleeds and jaundice due to liver damage. The final effects of the disease can induce hypotension, shock, and occasionally seizures or coma. In unvaccinated regions, the fatality rate may be between 15% and 50%—some of these deaths can be attributed to bacterial infections after the virus and kidney failure. If the patient recovers, they have immunity to the virus.
