Basic features?) Portal of Entry: Mode of Transmission Symptoms: Is there a vaccine available? Treatment: Means of Epidemiologic Control: Other interesting facts about this pathogen?Explanation / Answer
Ebola virus disease
1)causative agent- Ebola virus
2)Brief description about pathogen- The pathogen Ebola virus is a virological taxon from family filoviridae. The members of this geans are called Ebola viruses. Each species of the genus Ebola virus has one member virus and four of this cause Ebola virus disease in humans.

6)There is no vaccine available for this disease.
7) Treatment -No specific treatment is currently available .But supportive care with rehydration and symptomatic treatment should be done.
8)Epidemiological control done by isolation of patients and contact tracing. People who infected by Ebola virus should wear protective clothing like masks, gloves, gowns, goggles . Contact tracing is considered important to control outbreaks. It involves finding every one who had close contact with infected individual and watching them for signs of illness .
9) Interesting facts about pathogen -Ebola virus were first described after outbreak of Ebola virus disease in southern Sudan. The name of Ebola virus is derived from Ebola river in Zaire.
