Its a tropical disease.
I was going by this:
SURVIVAL OUTSIDE HOST: The virus can survive in liquid or dried material for a number of days. Infectivity is found to be stable at room temperature or at 4°C for several days, and indefinitely stable at -70°C (6, 20). Infectivity can be preserved by lyophilisation.

the colder it is the longer the virus stays alive?
Ebola samples are stored in -70 freezers indefinitely in the lab.
The colder, the longer lived.
Sitting in a hot car on a sunny day for a day or two would likely kill it.
