The COVID19 pandemic has taken a serious toll on the world, at the same time; there have been many patients who have recovered from the disease. However, a new study has found that many recovered patients might be still dealing with the disease. Experts have said they might be spreading the virus without having any symptoms. This study has been done by scientists from Italy. They have found that nearly 17 percent of the patients who have recovered from COVID19 has tested positive again in doctor’s follow up visits. Scientists from Agostino Gemelli University Polyclinic have looked at recovering patients to see the reaction of their bodies after treatment and quarantine. The study has enrolled 131 patients, who have followed the guidelines of the World Health Organization (WHO) for closing quarantine after the infection.
The study has found those patients who have met WHO’s guidelines for recovering COVID19 patients, nearly 16.7 percent of them have tested positive for the disease again during the follow-up check-ups. Experts have said that recovered patients who are still dealing with a sore throat and running nose are at a higher risk of being diagnosed with COVID19 again. The study has noted that recovered patients might be asymptomatic haulers of the virus. The lead author of the study, Francesco Landi has said that it is uncertain whether the persistent presence of the virus fragments is a sign of patients being contagious. Experts have revealed that the RT-PCR test only identifies a small fragment of the virus. A positive swab test tells whether a person is still shedding viral fragments, however, it does not confirm whether the person is still infectious or not.
The study shows no difference between age and gender of the patients who are testing positive or negative for COVID19 after recovery. Experts have highlighted a very important point that none of the patients has shown any kind of symptoms like fever or cough before testing positive for the disease again. They all have shown significant improvement in their health. Although a large group of patients has reported having symptoms such as fatigue, cough, and breathing difficulties, however, none of these signs has played a major role in patients getting a new positive test, said the experts.
