About Ebola Virus Disease

  • The first instances of the disease, formerly known as Ebola Hemorrhagic Fever, were discovered in Guinea in December 2013.
  • Later, the illness spread to the nearby countries of Sierra Leone and Liberia.
  • Bundibugyo, Sudan, and Zaire are three of the six strains that have historically caused significant outbreaks.
How does it spread?
  • The Pteropodidae family of fruit bats is regarded to be a natural host for the Ebola virus.
  • The virus travels from human to human and is acquired by people from wild animals (through broken skin or mucous membranes).

What are the symptoms?

  • Fever
  • Fatigue
  • Muscle pain
  • Headache
  • Sore throat
This is followed by:
  • Vomiting
  • Diarrhoea
  • Rash

How can it be diagnosed?

  • Clinically separating EVD from other infectious disorders such malaria, typhoid fever, and meningitis can be challenging.
  • Numerous pregnancy symptoms and Ebola disease symptoms are remarkably similar.
  • The following diagnostic techniques are used to confirm that symptoms are brought on by Ebola virus infection:
    • Enzyme-linked immunosorbent assay for antibody capture (ELISA)
    • RT-PCR assay (reverse transcriptase polymerase chain reaction)

Treatment:

  • The Ervebo vaccine has been shown to be effective in protecting people from the species Zaire ebolavirus
  • Two monoclonal antibodies (Inmazeb and Ebanga) were approved for the treatment of Zaire ebolavirus (Ebolavirus) infection in adults
  • Remdesivir was also tested as an Ebola treatment.
