Treatment centres and isolation zones were set up to reduce the spread of the virus and face-masks, gowns and gloves were used. Safe burial practices also helped to limit transmission of the virus, as did screening of passengers at international and domestic ports and airports.

How transmissible is Ebola?

Ebola is contagious. The virus spreads through direct contact (via broken skin or mucous membranes, in the nose, mouth, or eyes).
