Ebola Virus: Transmission, Symptoms, and Prevention
Overview
Ebola virus disease (EVD), commonly known as Ebola, is a rare but severe and often fatal illness. It is caused by the Ebola virus and is characterized by a range of symptoms, including fever, muscle pain, and hemorrhagic manifestations.Transmission
Ebola virus is primarily transmitted through direct contact with the bodily fluids of an infected person, such as blood, saliva, vomit, or feces. It can also be transmitted through contact with objects that have been contaminated with the virus, such as clothing, bed linens, or medical equipment.In certain parts of the world, Ebolaviruses may also spread through the handling and consumption of wild animals, particularly fruit bats and non-human primates. However, the exact mechanism of transmission from these animals to humans is not fully understood.
