You may have COVID for this number of days and not know it, according to a study

Previous studies have the wrong period of incubation of the virus. This study defines the right of registration.


Part of what makes very contagious coronavirus is his sneaky, the period of asymptomatic incubation. Up to a recent date, the general rule is that most cases have emerged between one and 14 days after the exposure, with most casesrevealing symptoms around the fourth or fifth day. But a new study published in the magazineScientific progress Patients can remain asymptomatic determined formore than we thought.As it is, patients are more likely to show their first symptoms approaching eight days.

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

Of course, the understanding of the Covid incubation period can make a huge difference to know if we successfully contain the virus. "Providing to the health authorities aPotentially more precise figure For the incubation period, the results could informGuidelines for confinement efforts Such as quarantine and studies on the transmission of illness, "researchers shared in a press release.

The new study is probably more precise than previous studies on the incubation subject because it used the largest patient samplesuch an analysis nowadays. As the researchers pointed out, "the few current estimates of four to five days were based on the small size of the samples, limited data, and self-reports that could be biased by the patient's memory or judgment or at the interviewer. Instead, this study was based on public databases the dates of trailing infection as they occur, to try to eliminate the recalling bias.

Finally, the researchers arrived at a more surprising conclusion: that it is possible that we underestimated the total duration of incubation of 14 days. The team determined that there are between five and 10 percent likelihood that it is the diseased intentioned case can put the other in danger by ending their quarantines too early. That's why, like the details of the virus continue to unfold, it is wise to sin by excess of prudence: if you think you have been exposed,do not wait for symptoms to confirm. When they come or if you do not change your ability to spread coronavirus. And for more on asymptomatic cases, know why80 percent of people in this age group are asymptomatic.
