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, and self-reports that could be biased by the memory or judgement of the patient or interviewer.

For the current findings, the research team developed a low-cost approach to estimate incubation periods and applied it to 1,084 confirmed cases of Covid-19 that had known histories of travel or residency in Wuhan, China.

Their approach improves accuracy by relying on a public database of dates of infection and uses the renewal theory in probability to reduce recall bias — the inaccurate recollection of past events.

Ultimately, the team calculated that the median incubation period was 7.75 days, with 10 per cent of patients showing an incubation period of 14.28 days.

The authors noted that this last finding may concern health authorities relying on the standard 14-day quarantine, but caution that their approach relies on several assumptions and may not apply to later cases where the virus may have mutated. (IANS)

Safety-pins with charms

For all the great inventions that we have at hand, it is amazing how we keep going back to the safety pin every single time to fix everything. Be it tears in our clothes, to fix our broken things, to clean our teeth and nails when toothpicks are unavailable, to accessorize our clothes, and of course, as an integral part of the Indian saree. Safety pins are a must-have in our homes. But how did they come about at all?

The safety pin was invented at a time when brooches existed. They were used by the Greeks and Romans quite extensively. A man named Walter Hunt picked up a piece of brass and coiled it into the safety pin we know today. He did it just to pay off his debt. He even sold the patent rights of this seemingly insignificant invention just so that his debtors would leave him alone.

Sesame oil bath is also called ennai kuliyal in Tamil

In South India, Deepavali marks the end of the monsoon and heralds the start of winter. The festival is usually observed in the weeks following heavy rain, and just before the first cold spell in the peninsula. The light and laughter that comes with the almost week-long celebration are certainly warm to the bones, but there is still a tradition that the South Indians follow to ease their transition from humidity to the cold.

Just before the main festival, the family bathes in sesame oil. This tradition is called 'yellu yennai snaana' in Kannada, or 'ennai kuliyal' in Tamil, which translates to 'sesame oil bath'. The eldest member of the family applies three drops of heated oil on each member's head. They must massage this oil into their hair and body. The oil is allowed to soak in for a while, anywhere between twenty minutes to an hour. After this, they must wash with warm water before sunrise.
