Expert States 21 -Day Quarantine For Ebola Is Dangerously Short

In a paper published Oct. 14 in the journal PLOS Currents: Outbreaks, Drexel University's Dr. Charles N. Haas argues that there's not enough evidence to support the recommended 21-day quarantine period for people suspected of harboring the virus.

"Twenty-one days has been regarded as the appropriate quarantine period for holding individuals potentially exposed to the Ebola virus to reduce the risk of contagion, but there does not appear to be a systemic discussion for the basis of this period," Hass said in a written statement.
Hass argues in the paper that outbreaks of Ebola in Zaire (1976) and Uganda (2000), as well as data from the first nine months of the current outbreak, suggest that there could be up to a 12-percent chance that someone could begin showing symptoms of Ebola after 21 days, according to the statement.
As Haas put it in an email to The Huffington Post, "the risk is certainly not zero of anyone beyond 21 days converting to symptomatic."
