Causes of Yellow Fever
Yellow fever is caused by a virus that is transmitted by mosquitoes. The virus is most commonly found in parts of Africa and South America. When a mosquito bites an infected person, the virus enters the mosquito's bloodstream. The mosquito can then transmit the virus to other people when it bites them.

- Drinking plenty of fluids
- Taking pain relievers to reduce fever and muscle pain
In severe cases of yellow fever, hospitalization may be necessary. Treatment in the hospital may include:
- Providing intravenous fluids
- Administering oxygen
- Treating other symptoms as needed
Conclusion
Yellow fever is a serious viral disease that is spread by mosquitoes. It can cause a range of symptoms from mild to severe, and in some cases can be fatal. The best way to prevent yellow fever is to get vaccinated. Other prevention measures include using insect repellent, wearing protective clothing, and sleeping under mosquito nets.
