Long-term effects of Covid19

Symptoms such as shortness of breath or hair loss during exercise are not thought to appear until three months after recovery from the new coronavirus infection (Covid19).

At a regular briefing on the 14th, the National Institute of Health and the National Medical Center of South Korea announced interim results of the “Covid19 Clinical Aftermath” study. The researchers studied and interviewed 40 adult patients who were hospitalized every three months after Covid19 was confirmed.

The result: three months after recovery, symptoms such as hair loss and shortness of breath on exercise were relatively common, and fatigue was still relatively high six months later. Some patients showed reduced lung function, which showed signs of recovery over time. On lung computed tomography (CT), pneumonia remained significant at the three-month time point, and most cases improved after six months, but some patients experienced “fibrosis,” in which the lungs gradually stiffened and impaired function.

Kwon Joon-wook, head of the second department of Bang Dae -bon, said, “The deterioration of lung function showed a high tendency in patients who were 60 years or older and seriously ill.” The patients suffered from psychological after-effects such as depression and post-traumatic stress disorder. Over time, depression decreased and post-traumatic stress disorder increased. “In China, 76 percent of recovered patients complained of more than one continuous clinical symptom, most of which were muscle weakness or sleep disturbance,” Kwon said. “In the U.S., there is an increase in mortality rate in patients with underlying diseases and some continuous symptoms in recovered patients,” he explained.
