About 10 percent of people admitted to hospitals due to coronavirus symptoms continued to suffer after-effects a year after being discharged, a recent study by a research group from the Ministry of Health showed.
The most common lingering symptom was decreased muscle strength of 7.4 percent, followed by difficulty breathing by 4.4 percent and lethargy by 3.5 percent according to the study.

Individuals experiencing a lost or altered sense of smell accounted for 1.6 percent, while those with altered taste were recorded at 1.0 percent. Some people suffered from several symptoms.
The study included 693 people with moderate or severe COVID-19 symptoms who were hospitalized between September 2020 and July 2021.
Individuals who continued to consult medical facilities about symptoms that appeared to be after-effects a year after being discharged stood at 9.8 percent.
While the number of people complaining of persistent symptoms decreases over time, “the aftermath remains with some,” said Akihito Yokoyama, head of the group for the Ministry of Health, Labor and Welfare.
“It is important to avoid infection,” said Yokoyama, a professor at Kochi University’s Department of Respiratory Medicine and Allergy, urging people to get vaccinated and follow safety precautions.
As for people with CT scan data, 5.1 percent showed lung effects one year after being discharged, according to the study.
