Disease outbreaks occur frequently, and no two outbreaks are ever the same.
There are always differences in magnitude and spread, and the ability to control and reduce fatality due to the outbreak will depend on the depth of scientific knowledge about the disease, availability of approved and well-known medical treatment, and the capacity of the healthcare system to put the disease under control.
