Context: Uganda recently declared the end of the Ebola disease outbreak caused by Sudan ebolavirus.

About Ebola Disease:

  • Ebola spreads through EBOV (Ebola virus) which is a virus belonging to the Filoviridae family of viruses.
  • It is mainly found in animals.
  • Ebola is a virus that causes severe inflammation and tissue damage throughout the body.
  • It is known as a haemorrhagic fever virus, because it can cause problems with the clotting system of the body and lead to internal bleeding, as blood leaks from small blood vessels.

  • Six different species of the virus have been found, but only four are known to cause disease in humans.
  • Ebola is spread through direct contact with body fluids ― blood, saliva, sweat, tears, mucus, vomit, faeces, breast milk, urine and semen of people infected with it.
  • It is also spread by touching things that have been contaminated with these fluids.
  • The virus is named after the Ebola river (Republic of Congo ) — as a village situated on its bank witnessed the first instance of the viral outbreak in 1976.


  • A vaccine for Ebola was approved by the Food and Drug Administration in 2019.
  • It is a one-dose shot that protects against the variant of the Ebola virus that has caused the most serious outbreak so far.
  • This vaccine is not likely to be effective against the Ebola Sudan strain that caused a 2022 outbreak in Uganda.
