Coronavirus may have longer incubation period than thought – Times of India


Chinese scientists have come up with a new estimate for the incubation period of Covid-19, which is around 7.76 days, longer than previous estimates of 4 to 5 days.

The study, published in the journal Science Advances, involves the largest amount of coronavirus patient samples to date.

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.

“Countries and health authorities have implemented various containment measures such as quarantines to slow the spread of Covid-19,” the Chinese researchers wrote.

“To work effectively, these strategies depend on understanding the disease’s incubation period, or the time between someone becoming infected and showing the first symptoms of the disease, and how much it varies from individual to individual,” they added.

However, researchers lack a reliable estimate of the incubation period of Covid-19.

The few existing estimates of 4 to 5 days were based on small samples sizes, limited data, a
