Ebola in West Africa - August 2014

 

Ebola Outbreak in West Africa update

The countries of Guinea, Liberia, Sierra Leone, and Nigeria in Western Africa are experiencing a large resurgence of the Ebola Virus (EVD). Over 3000 people have contracted the disease and 1546 people have died from symptoms in Guinea, Liberia, Sierra Leone, and Nigeria countries (29 Aug 2014, WHO). The current fatality rate is 53%. The virus is documented to have crossed borders via international travel. However, it is currently centred in Western Africa.
The outbreak is thought to be associated with bats and often spread to other humans via contact and droplet infection.

Ebola is a severe illness caused by Ebola virus. It is highly infectious, rapidly fatal, with a death of up to 90%, but can be prevented. It is spread through direct contact with body fluids like blood, saliva, urine, sperm, etc. of an infected person and by contact with contaminated surfaces or equipment, including linen soiled by body fluids from an infected person. The Ebola virus can be relatively easily eliminated with heat, alcohol-based products, and sodium hypochlorite (bleach) or calcium hypochlorite (bleaching powder) at appropriate concentrations.
