Yellow fever virus belongs to the Flavivirus family (subgroup arbovirus) and is an enveloped RNA virus. The virus shape is icosohedral with a lipid containing envelope. It is also known as a togavirus. Yellow fever virus is carried by mosquitoes and is common in Africa, Central and South America. The yellow fever virus is transmitted to humans when an infected female mosquito bites a human. Symptoms include fever, headache and nausea (flu-like symptoms). In serious cases there may be liver and kidney damage (necrosis), and even death. Yellow fever causes yellowing of the skin due to jaundice. There is no treatment for yellow fever and 5% of those infected die. Yellow fever vaccines can provide immunity.
