West Africa is dealing with the deadliest Ebola outbreak on record as international health organizations struggle to contain it.

Two Americans working in the region have tested positive for the deadly virus that has been spreading since March.

There have been at least 759 confirmed cases in Guinea, Sierra Leone and Liberia have been infected in the last four months -- 467 of them have died.

Doctors say the Ebola virus doesn't spread in the air simply like the flu - it spreads through direct contact with bodily fluids or infected animals. 

While the virus is able to live on it's own outside an infected person for some time - experts say it is "fragile" - soaps, detergents, heats and disinfection can kill it.

Here in the US experts say we should be aware of the threat but not fearful.

There have not yet been any cases of Ebola being spread to a developed country.

Doctors say that is because people generally transmit the infection when they are very sick - and here in the US people usually have access to clean hospitals with proper infection control.
