According to a study published on Friday in the medical journal The Lancet, the symptoms of Covid-19 may last as long as six months. The study investigated the first people hospitalized with the disease.
The study focused on 1,733 people hospitalized with Covid-19 who were hospitalized in Wuhan, China (coronavirus was first detected) from January to May last year. Many people were hospitalized before the disease got its name.

Six months after the initial diagnosis, approximately three-quarters of patients report persistent symptoms. 63% said they still felt tired or muscle weakness, 23% said they were anxious or depressed, and 26% said they did not sleep well.
The study’s author and deputy director of the study, Dr. Cao Bin, said: “Our analysis shows that most patients will still be infected with the virus at least after discharge, and emphasize the necessity of care after discharge.” Beijing China-Japan Friendship Hospital Breathing The disease center said in a statement.
However, this is an observational study, which means that it is impossible to directly link these symptoms to the coronavirus. To show a real connection, research needs to compare the outcome of Covid-19 with similar infections that can also cause pneumonia while in hospital.
Dr. Hana El Sahly, associate professor of molecular virology, microbiology and medicine at Baylor College of Medicine in Houston, said: “I hope to see data on patients who received medications other than Covid-19 during this period.” She was not involved in this new study. .
El Sahly said: “Being admitted to pneumonia is a traumatic event for anyone,” adding that it is not uncommon for these patients to have lingering symptoms.

The study also found that those with the most severe illness still had trouble breathing after six months. More than half of people who need a ventilator to prevent illness later experience a disease that reduces the flow of oxygen from the lungs into the blood. And they are more likely to have difficulty completing the walking endurance test.
However, it is not clear whether the impaired lung function is caused by a virus or related to an underlying health condition. Although the study participants are all hospitalized, few patients enter the intensive care unit, which means that the study results may not apply to the most sick patients.
Cao said: “Because Covid-19 is a new disease, we are just beginning to understand some of its long-term effects on patient health.” He added that this study may help emphasize that even Covid-19 patients need to be discharged from the hospital. Increase care.
