One of the following causes Ebola fever

Out of the options given, viruses cause Ebola fever. Ebola fever, also known as Ebola virus disease, is a severe and often fatal illness caused by the Ebola virus. The virus is a member of the family Filoviridae, which also includes the Marburg virus. The Ebola virus was first identified in 1976 during an outbreak in Sudan and the Democratic Republic of Congo, and since then, there have been several outbreaks in various parts of Africa. The Ebola virus is highly contagious and is spread through contact with bodily fluids of infected people or animals. The virus can cause a range of symptoms, including fever, fatigue, muscle pain, headache, and sore throat, among others. In severe cases, it can lead to bleeding and organ failure. While there is currently no specific treatment for Ebola fever, supportive care can help improve the chances of survival. Prevention efforts include strict infection control practices in healthcare settings, safe burial practices for those who have died from the disease, and community education and engagement. In summary, viruses cause Ebola fever, not bacteria, fungi, or protozoa.
