Yellow fever is a virus from mosquitos in Africa and South America, a severe spreading infection. The infection ranges from aches to jaundice.
Yellow fever spread
The virus only spreads through mosquito bites, not close contact with someone infected. They mainly bite during the day and can spread malaria and dengue. Even vaccinated, try to avoid mosquito bites while traveling. Use mosquito nets, clothes that cover the entire body, and insect repellent that contains 30%–50% DEET.
Yellow fever found in:
- Parts of sub-Saharan Africa
- Parts of South and Central America
- Trinidad and Tobago (Caribbean islands)
Yellow fever vaccination
- Vaccination of yellow fever is recommended if you are traveling to places where they are mostly found.
- Or when a country requires you to have certification of vaccination before entering. For the certificate to be valid, you must have had vaccination at least 10 days prior.
