21 Days Not A Long Enough Quarantine For Ebola, New Study Suggests

Branham said the university consulted with county health officials who said the CDC’s 21-day incubation period might not be accurate. She pointed to one study conducted by Drexel University that concluded there is a 12 percent chance that someone could be infected even after the 21-day quarantine. She also referred to a report from the World Health Organization that said Senegal had Ebola case findings after 42 days.

But looking more broadly at data from other Ebola outbreaks, in Congo in 1995 and recent reports from the outbreak in West Africa, the range of deviation is between 0.1 and 12 percent, according to Haas. This means that there could be up to a 12 percent chance that someone could be infected even after the 21-day quarantine.
“While the 21-day quarantine value, currently used, may have arisen from reasonable interpretation of early outbreak data, this work suggests reconsideration is in order and that 21 days might not be sufficiently protective of public health,” Haas said.
