Have you been in contact with possible positive cases of coronavirus? Do you suspect that you have been exposed to the virus? Do you think you can be infected? Well, an expert tells you what is the first thing you have to do, and it is not submitting to a test.

Science Alert spoke to Lisa Lee, Virginia Tech professor and public health expert: “If you’ve been exposed, quarantine.”

“Immediately separate yourself from anyone, and do it for 14 days “, Lee explains.

From the moment of infection to the appearance of the first symptoms, an average of four to five days pass, but the incubation period lasts between two and fourteen days, so the quarantine period is recommended to last two weeks, regardless of how the infected feels.

“The idea of ​​having been exposed and wait around for a test it’s a bad idea, “Lee says. The teacher insists that even when symptoms are not shown, the virus can spread and put others at risk of infection and even death.

Once we are isolated, it is best to have the test about a week after being exposed to the virus. If the first test is negative, it is recommended to do a second test at 12 days of the suspicious event. And if you can, take another test at the end of the 14-day quarantine to be able to come out of your isolation with greater peace of mind.

The most contagious day is the day before symptoms appear

“You are infectious sometime between contracting the virus and beginning to have symptoms, but we don’t know exactly when“says Lisa Lee. It is suspected that the day before showing symptoms is the most infectious a person is.

If you share a house with other people, the recommendation is to wear a mask at home and distance yourself as much as possible from those partners. If possible, use another bathroom, and in any case, if you can’t keep your distance, keep the house well ventilated.
