West Africa is struggling with the worst Ebola outbreak since the disease was identified in 1976, and the first case has been diagnosed in the United States.
Below are some facts regarding the outbreak:
- The outbreak has killed 3,338 people, or 47
percent of the 7,178 known to have been infected as of Sept. 28, predominantly
in Liberia, Sierra Leone and Senegal. The disease – which emerged in a remote
forest region of Guinea in March – has also turned up in Nigeria and Senegal,
but officials say the disease has been contained in those two countries.
- There is no vaccine or cure for Ebola, a
hemorrhagic fever. In past outbreaks, fatality rates have reached up to 90
percent. Ebola causes fever, flu-like pains, bleeding, vomiting and diarrhoea.
- Pharmaceutical companies are working on
experimental Ebola vaccines and antiviral drugs, but a significant number of
doses will not be available until at least the first quarter of 2015.
- Ebola is not airborne. It is transmitted through
blood, vomit, diarrhoea and other bodily fluids. Healthcare workers in West
Africa have been among the hardest hit by the outbreak.
- Ebola symptoms generally appear between two and
21 days after infection, meaning there is a significant window during which an
infected person can escape detection, allowing them to travel. However, they
are not considered contagious until they start showing symptoms.
- Recovery from Ebola depends on the patient's
immune response. People who recover from Ebola infection develop antibodies
that last for at least 10 years.
- The U.S. Centres for Disease Control and
Prevention (CDC) has estimated that the number of infections could rise to up
to 1.4 million people by early next year without a massive global intervention
to contain the virus.
- The United States, Britain, France, China, Cuba
and international organizations are pouring funds, supplies and personnel into
the affected parts of West Africa.
- Ebola's suspected origin is forest bats. The
virus was first identified in 1976 in what is now known as Democratic Republic
of the Congo.
