The Golden Number: 42 Days
With a while to wait before we see an approved Ebola vaccine become available, the virus must be effectively contained in order to see an end to the outbreak. The time it takes for symptoms to appear after exposure to the virus is known as the incubation period – and this is usually 2-21 days. If health care teams don’t see any new cases during the next 42 days, that is, the length of two incubation periods, then the outbreak can be declared officially over. Until that day comes, health care workers are attempting to contain the virus in treatment centers like the one below.
The current outbreak’s death toll has now reached 1,229, with total cases estimated to have risen to 2,240.
