You Could Have COVID for This Many Days and Not Know It, Study Says - MSN Money

Previous studies got the virus's incubation period wrong.

Part of what makes coronavirus so highly contagious is its sneaky, asymptomatic incubation period.

While just 10 percent of the infected study subjects remained asymptomatic for a full 14 days, the researchers found that the median incubation period was 7.75 days, three to four days later than most previous estimates.

"By providing health authorities with a potentially more accurate figure for the incubation period, the results could inform guidelines for containment efforts such as quarantines and studies investigating the disease's transmission," the researchers shared in a press release.

The new study is likely more accurate than previous studies on the subject of incubation because it used the largest patient sample in any such analysis to date.
