What Is the Ebola Virus?
Cause of Ebola
Ebola is caused by an infection with the Ebola virus.
Where Did Ebola Virus Get Its Name?
Ebola first appeared in 1976 in 2 simultaneous outbreaks, in Nzara, Sudan, and in Yambuku, Democratic Republic of Congo.
Ebola virus got its name from a river in the Democratic Republic of the Congo (formerly Zaire), in Africa, where it was first recognized.
There are five types of Ebola species
1.Zaire ebolavirus (EBOV; previously ZEBOV) -ZEBOV has the highest case-fatality rate of the ebolaviruses, up 90%. Average case fatality rate of approximately 83% over 27 years
2.Bundibugyo ebolavirus (BDBV)
3.Reston ebolavirus (RESTV)
4.Sudan ebolavirus (SUDV)
5.Taï Forest ebolavirus (TAFV).
How Ebola virus is transmitted ?
Transmission of Ebola: Exposure to Infected Body Fluids
Ebola is introduced into the human population through close
contact with the blood, secretions, organs or other bodily fluids of infected
Transmission of Ebola: Direct Contact With an Infected Person
Ebola then spreads in the community through human-to-human transmission, with infection resulting from direct contact (through broken skin or mucous membranes) with the blood, secretions, organs or other bodily fluids of infected people, and indirect contact with environments contaminated with such fluids. Burial ceremonies in which mourners have direct contact with the
body of the deceased person can also play a role in the transmission of Ebola.
Men who have recovered from the disease can still transmit the virus through their semen for up to 7 weeks after recovery from illness.
Ebola spreads through Objects or medical tools
People can also be exposed toEbola virus through contact with objects, such as needles, that have been contaminated with infected secretions.
Signs and Symptoms of Ebola Virus Disease
Symptoms may appear anywhere from 2 to 21 days after exposure to ebolavirus though 8-10 days is most common.
Diagnosis OF Ebola
Ebola virus infections can be diagnosed definitively in a laboratory through several types of tests:
Vaccine and treatment FOR Ebola Virus
The prevention of Ebola HF presents many challenges. Because it is still unknown how exactly people are infected with Ebola HF, there are few established primary prevention measures.
No licensed vaccine for EVD is available. Several vaccines are being tested, but none are available for clinical use.
Severely ill patients require intensive supportive care. Patients are frequently dehydrated and require oral rehydration with solutions containing electrolytes or intravenous fluids.
No specific treatment is available for Ebola. New drug therapies are
being evaluated for Ebola virus.
