90% of recovered COVID-19 patients experience side effects: Study

New Delhi : Nine in ten coronavirus patients reported experiencing side-effects such as fatigue, psychological after-effects and loss of smell and taste after they recovered from the disease, according to a preliminary study by South Korea.

In an online survey of 965 recovered COVID-19 patients, 879 people or 91.1% responded they were suffering at least one side-effect from the disease, the Korea Disease Control and Prevention Agency (KDCA) official Kwon Jun-wook told a briefing.

Fatigue was the most common side-effect with 26.2% reading, followed by difficulty in concentration which had 24.6%, Kwon said.

Other after-effects included psychological or mental side-effects and loss of taste or smell.

Kim Shin-woo, professor of internal medicine at Kyungpook National University School of Medicine in Daegu, sought comments from 5,762 recovered patients in South Korea and 16.7% of them participated in the survey, said Kwon.

While the research was done online for now, lead researcher Kim will soon publish the study with detailed analysis, he said.

South Korea is also conducting a separate study with some 16 medical organisations on potential complications of the disease through a detailed analysis involving CT scans on recovered patients next year, Kwon told the briefing.
