Symptoms of Yellow Fever

Yellow fever develops quickly, with symptoms occurring three to six days after exposure. The initial symptoms of the infection are similar to those of the influenza virus. They include:

Acute Phase

This phase usually lasts for three to four days. Common symptoms include: Fever.

  • Muscle aches, particularly in your back and knees.
  • Sensitivity to light.
  • Nausea, vomiting or both.
  • Loss of appetite.
  • Red eyes, face or tongue.

After the acute phase is over, symptoms will begin to go away. Many people recover from yellow fever at this stage, but some people will develop a more serious version of this condition.

Toxic Phase

The symptoms that you experienced in the acute phase may disappear for up to 24 hours. Then, those symptoms will return, along with new and more serious symptoms. These include:

  • Yellowing of your skin and the whites of your eyes (jaundice)
  • Abdominal pain and vomiting, sometimes of blood
  • Decreased urination
  • Bleeding from your nose, mouth and eyes
  • Slow heart rate (bradycardia)
  • Liver and kidney failure
  • Brain dysfunction, including delirium, seizures and coma

This phase of the disease is often fatal, but only 15 percent of people with yellow fever enter this phase.


There’s no cure for yellow fever. Treatment involves managing symptoms and assisting your immune system in fighting off the infection through vaccine.

In addition to getting the vaccine, you can help protect yourself against yellow fever by protecting yourself against mosquitoes. This can be achieved by making use of well-treated mosquito net.
