A current outbreak is raging in the three West African states of Liberia, Sierra Leone, and Guinea. The outbreak, which has killed over 670. People is the largest Ebola outbreak on record. It won't be considered over until no new confirmed cases appear for 42 days. There have been at least 1, 093 confirmed, probable, and suspected cases of Ebola in the current outbreak. Humans contract the virus from infected animals or other humans through contact with bodily fluids. Typically, the virus kills around 90 % of those who are infected. But thanks to early treatment, the number has dropped to 60 % in the current outbreak. Because it can take between 2 and 21 days for symptoms to show, health officials suggest keeping a 21 day fever watch. In addition to fever, other symptoms are headaches, joint pain, lack of appetite, difficulty breathing, and sore throat. In later stages, Ebola causes diarrhea, vomiting, and internal bleeding. Though it's been almost 40 years since the disease was first discovered in 1976, the grim reality is that there are currently no cures or effective treatments for the virus.
