Ebola Tai Forest
Ebola Tai Forest (TAFV) originated in Cote d'Ivoire in 1998' two chimpanzees were found dead with brown blood in their hearts and lungs. Unlike the other ebolaviruses, TAFV does not liquefy internal organs; they remain intact. Symptoms begin with headache and fever. Next comes nausea and bloody vomit, and finally blood filling the lungs and turning brown, killing the heart. TAFV has only one recorded case in humans; a scientist working in Cote d'Ivoire contracted the disease after conducting an autopsy on one of the infected chimpanzees. He was treated in Switzerland and survived.
