It turns out that about half of Wuhan's new corona patients continue to have symptoms even after one year

The outbreak of 'Long COVID ', a long-lasting symptom of the new coronavirus infection (COVID-19), has been reported, and millions of people in the United States have permanent sequelae. , It is feared that the economic burden on society as a whole will increase. Much has not yet been elucidated about long COVID, but a new study shows that about half of Wuhan-infected people are still symptomatic one year after infection.

At the end of January 2020, Wuhan City, China was closed due to the spread of the new coronavirus infection (COVID-19). As of December 2020, Wuhan City reported a cumulative total of 50,354 infections in the city, but it is estimated that there were actually 500,000 infected people, which is 10 times that number.

At that time, many people infected with COVID-19 were mildly ill, but some were hospitalized and treated. In a new study, a follow-up survey was conducted on 2,433 people who were admitted to two hospitals in Wuhan with COVID-19 and then discharged from February 12 to April 10. Many long-term sequelae and long-term COVID outbreaks have been reported for COVID-19, but it was investigated how much the patient had recovered after one year. Of the patients included in the follow-up survey, 49.5% were male and 50.5% were female, with a median age of 60 years and 27.9% of all critically ill patients as defined by WHO.

According to the survey, 45% of patients still reported at least one symptom one year after the infection. Common symptoms include fatigue, sweating, chest tightness, anxiety, and muscle aches. Only 680 critically ill patients will have symptoms, up to 54%, but of the 1752 non-severe patients, 41.5% have reported long COVID. There was no big difference.

As of January 2021, reports of Wuhan patients 6 months after infection were announced, and at this time, '76% of patients hospitalized with COVID-19 had some symptoms even after 6 months. I am suffering from. ' It can be said that the ratio has decreased slightly after one year.

Survey results other than Wuhan also show that the symptoms of long COVID are not limited to critically ill patients. A large UK survey of 273,618 people, published on September 28, 2021, found that more than half of unhospitalized patients had long COVID symptoms 6 months after infection. Shown .

This study, which followed patients in Wuhan, showed that becoming severe 'increased the likelihood of long COVID' and 'becomes a risk factor for exhibiting three or more symptoms.' Elderly patients and women are also risk factors for persistent symptoms.

Since there is no target group in this study and not all discharged patients participated, the data may be biased toward 'people who are willing to participate in follow-up studies'. .. It should also be noted that it is limited to infected individuals before the development of various mutant strains.

On the other hand, the results of this study are consistent with the results of long COVID studies published in the past, and the researchers concluded that 'the health effects of COVID-19 far exceed the scope of acute infections. I have. '
