Reason for the term-‘quarant’ine = 40 days, not 21.
Via Daily Mail:
The recommended 21-day quarantine period for the Ebola virus is not long enough to contain the spread of the disease, a new study has warned.
The World Health Organisation (WHO) advises the incubation period for the virus is between two and 21 days.
It is thought that if someone who has been in contact with an Ebola victim but does not develop symptoms after that point, has not been infected.
But a study by scientists at Drexel University in Philadelphia has found there is a 12 per cent chance the deadly virus could lay dormant in a person’s body for longer than the three-week period.
