What is yellow fever?

Yellow fever is a flu-like ailment spread by mosquitoes that can become potentially dangerous. It is characterized by high fever and jaundice or yellowing of the eyes and skin. The condition could not be cured but can be prevented with a vaccine.

The Flavivirus is responsible for the condition and transmitted if an infected mosquito bites an individual. Take note that mosquitoes can become infected by the virus if they feed on an infected monkey or human.

What are the indications?

Yellow fever rapidly develops with symptoms that arise within 3-6 days after exposure. The primary indications of the infection are the same as the flu such as:

  • Muscle pain
  • Headache

  • Abdominal pain
  • Diminished urination
  • Seizures
  • Vomiting
  • Issues with the heart rhythm
  • Delirium

Anyone starting at 9 months old up to 59 years of age and living or traveling to areas where the risk for yellow fever is high should receive the vaccination.
