Yellow Fever is a transmittable viral disease predominately carried by Aedes and Haemagogus mosquito species. Symptom appearances vary from 3 to 6 days with most infections causing serious illness and are split into two stages. The first stage includes fever, muscle pain, nausea, vomiting, headaches, and weakness. The second stage includes visible bleeding, jaundice (or yellowing of the skin, for which the disease gets its name), kidney and liver failure, leading to death within two weeks. Although there is no distinctive treatment, medicines are used to relieve various symptoms. The World Health Organization considers Yellow Fever to be endemic in 29 African and 13 Central and South American Countries.
