Definition of Ebola virus disease
Ebola virus disease (EVD) is a severe illness caused by the Ebola virus, which is part of the Filoviridae family. The disease is characterized by the sudden onset of symptoms, including fever, fatigue, muscle pain, and sore throat. As EVD progresses, it can lead to vomiting, diarrhea, and in severe cases, organ failure and hemorrhaging. The mortality rate for Ebola can vary significantly, often ranging from 25% to 90%, depending on the outbreak and the specific virus strain involved.
The primary mode of transmission of the Ebola virus is through direct contact with bodily fluids of infected individuals or animals. This includes blood, saliva, sweat, and other secretions. Human-to-human transmission can occur via unprotected physical contact during caregiving or through sharing needles. Early recognition and immediate isolation of cases are critical for controlling outbreaks.
Overview of the Ebola virus
The Ebola virus was first identified in 1976, during simultaneous outbreaks in Sudan and the Democratic Republic of the Congo. There are five recognized species of the Ebola virus, namely Zaire, Sudan, Taï Forest, Bundibugyo, and Reston. Of these, the Zaire species is known for the highest mortality rates reported during outbreaks.
Ebola viruses are enveloped, single-stranded RNA viruses. They contain a complex structure that enables them to invade and replicate within host cells. The virus primarily targets cells of the immune system and leads to dysregulation, which causes severe immune response and subsequent tissue damage.
"The emergence of the Ebola virus is considered one of the most significant events in the history of infectious diseases, prompting extensive research and global health responses."
