The virus is not very resistant and can easily be killed/destroyed by
- drought and
- in the washing machine (for example on clothing contaminated by vomit).
The virus is only able to survive for a very short period of time in the open air at a normal temperature.
In contrast, it can survive for several days at 4°C on a glass surface. It seems that this can play a role in the transmission of the virus in a medical setting.
The idea that the Ebola virus can mutate and thus spread easily from one person to another in the air is not currently supported by scientific evidence.
