Of COVID-19 patients who have fully recovered, about one in six still test positive for the virus




Author: “Our findings show that rehabilitation of patients with a certain percentage of COVID-19 may still be asymptomatic carriers of the virus.”


Rome- Although the coronavirus pandemic has dealt a heavy blow to the world, it is gratifying that tens of millions of people have recovered from COVID-19. Unfortunately, a new study found that many of them may still be sick and don’t know. Researchers in Italy said that among patients who have fully recovered from COVID-19 infection, nearly 17% still tested positive at the follow-up doctor.

Researchers at Agostino Gemelli University Policlinic studied a group of COVID patients who were recovering to understand how their bodies responded after treatment and isolation. The study included 1

31 patients, all of whom met the World Health Organization’s guidelines for ending isolation after infection. These guidelines require patients to not have a fever for three days. They must also improve their symptoms and test negative for COVID at least twice every 24 hours.

Although the group initially met the WHO criteria for rehabilitation of coronavirus patients, 22 (or 16.7%) participants tested positive for COVID during follow-up screening. The researchers added that patients who are still dealing with sore throat and stuffy nose are more likely to receive a new positive test.

Lead researcher Francesco Landi (Francesco Landi) said in the media: “Our findings indicate that a certain percentage of recovered COVID-19 patients may still be asymptomatic carriers of the virus.” “Contain SARS- The main problem of the CoV-2 pandemic infection still needs to be resolved, that is, whether the persistence of viral fragments means that the patient is still infectious. RT-PCR tests look for small fragments of viral RNA. A positive swab test can reveal whether the patient is still It is shedding virus fragments, but it is impossible to tell whether they are infectious.”

Are there signs that you may still have COVID-19?

The results also showed that there was no significant difference between the age or gender of patients who tested positive or negative. None of the recovered patients had a fever, and none of the patients showed improvement in symptoms before the new positive test.

Indeed, most people continue to experience symptoms, including fatigue (51%), difficulty breathing (44%), and coughing (17%). However, these factors are not the main factors for participants who test positive or remain virus-free. Among the positive COVID patients, only sore throat (18% vs. 4%) and rhinitis (27% vs. 2%) were significantly more than the negative patients.

Randy added: “Clinicians and researchers have focused their attention on the acute phase of COVID-19, but they need to continue to monitor its long-term effects after discharge from the hospital.”
