- Yellow fever is named so because it is often associated with jaundice, which causes a yellowing of the skin and eyes.
- Yellow fever is endemic in 47 countries in Africa, Central, and South America, according to the World Health Organization (WHO).
- About 90% of reported cases occur in sub-Saharan Africa.
- The yellow fever virus is transmitted to humans through the bites of infected mosquitoes, with the most common vector being the Aedes species – the same mosquito that spreads other viruses like Zika, Chikungunya, and Dengue.
- The Haemogogus mosquito also spreads the virus, mainly found in jungle areas. Yellow fever cannot be spread from one person to another through contact.
