Filoviruses are a family of viruses known for causing severe hemorrhagic fevers in humans and animals. The most well-known members of this family are the Ebola virus and the Marburg virus. These viruses are typically transmitted through direct contact with infected bodily fluids, leading to outbreaks that can be deadly. Filoviruses are characterized by their filamentous shape and can cause symptoms such as fever, vomiting, and bleeding. The incubation period can vary, but symptoms usually appear within 2 to 21 days after exposure. Due to their high mortality rates, research and containment efforts are critical in managing outbreaks.
