What is Yellow Fever?

Yellow fever is a viral disease transmitted by mosquitoes infected with the yellow fever virus. It primarily affects tropical regions of Africa and South America. Yellow fever can cause a spectrum of symptoms, from mild flu-like illness to severe forms with high fever, jaundice (yellowing of the skin and eyes), and bleeding. Vaccination against yellow fever is essential for travelers to endemic areas.

In first aid contexts, recognizing symptoms such as fever, headache, muscle pain, nausea, and jaundice prompts early intervention and referral for medical evaluation. Prevention focuses on mosquito bite prevention measures, including insect repellents, mosquito nets, and wearing protective clothing. Public health strategies such as vaccination campaigns and mosquito control programs help reduce yellow fever transmission and outbreaks.
