1. Virus reservoir :Fruit bats
3. Primary human infection2. Epizootic in primates 4. Secondary transmission
Fruit bats are considered to be the natural host of the Ebola virus.

The incubation period, or the time interval from infection to onset of symptoms, is from 2 to 21 days.
No report of disease transmission through air-borne route
EVD surveillance in Thailand, showed that no confirmed EVD cases had been reported.
