B. Ebola

Ebola, also known as Ebola virus disease (EVD), is an emergent infectious disease that often has a high fatality rate. It is characterized by the sudden onset of high fever, severe weakness, muscle pain, headache, sore throat, followed by vomiting, diarrhea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding (also known as hemorrhaging).

Ebola is particularly deadly because it can lead to multiple organ failure and severe dehydration due to the vomiting and diarrhea. The fatality rates have varied from 25% to 90% in past outbreaks, with an average rate around 50%. However, with proper medical care, including rehydration and symptomatic treatment, the chances of survival can improve.

The disease is caused by the Ebola virus, which is transmitted through direct contact with the bodily fluids of an infected person or animal or through exposure to contaminated environments.
