In some people, the new coronavirus can persist in the body for at least two weeks after the symptoms of the disease disappear, Chinese researchers have found.

A small study, published in JAMA, involved four healthcare professionals, ages 30 to 36. They contracted COVID-19 while working and were treated at Zhongnan Hospital of Wuhan University between January 1 and February 15. The patients were taking the antiviral drug oseltamivir.

Patients were considered recovered when their symptoms disappeared and tested negative for COVID-19 for two consecutive days. After that, the participants were quarantined at home for 5 days, and then, from 5 to 13 days, they had throat swabs. The results of each test between the 5th and 13th days were positive.

"At least some of the recovered patients may still be virus carriers," the researchers wrote.

Krys Johnson, an epidemiologist at Temple University who was not involved in the study, explained that this is typical for some viruses. For example, the Zika virus and viurs Ebola remain in the body for several months after recovery.

According to Ebenezer Tumban, a virologist at Michigan Technical University, who was not involved in the study, the test is aimed at finding genetic fragments of the virus in the body. Tamiflu significantly reduced the number of copies of the virus in the participants' bodies, so the test did not detect it.

And after the cessation of antiviral treatment, viruses could begin to multiply again at a level sufficient for detection with a test, but not for symptoms. These people did not cough or sneeze, their viral load was also low, and therefore closer contact is needed for the virus to spread.

At the time of publication of the article, none of the family members of the study participants had tested positive for coronavirus. The authors noted that patients, as health workers, took the necessary precautions to avoid spreading the disease at home.

As of today, it is not yet known how long the immunity against coronaviruses lasts, as well as what the probability of COVID-19 mutations is.
