It is thought that fruit bats of the Pteropodidae family are natural Ebola virus hosts." According to the description above and your understanding of the course content (terminology) on dynamics of disease transmission, identify the incorrect statement. a. EVD can start as a common source, and thereafter become a propagated epidemic b. EVD is usually transmitted as an airborne infection c. EVD is a zoonotic infection d. EVD is a contagious disease
The average EVD case fatality rate is around 50%. Case fatality rates have varied from 25% to 90% in past outbreaks.
