What is Yellow Fever?
Yellow fever is a haemorrhagic viral illness transmitted by bites from infected mosquitoes. “Yellow” refers to the skin colour presented by some patients as a consequence of liver swelling.
Yellow fever is an endemic (common) disease in tropical zones of Africa, Central America and South America, and it represents a risk for travellers who go to these areas.
There are around 200,000 cases of yellow fever every year around the world, which cause around 30,000 deaths.
