The results of the study show that even people who have recovered from Covid-19 may suffer long-term health effects from the outbreak of the coronavirus, which has infected more than 90 million people worldwide.
The study is the largest to date and was published in the medical journal The Lancet on Friday. Studies have found that fatigue and difficulty sleeping are the most common symptoms after Covid-19, which occur in 63% and 26% of patients, respectively, six months after the initial diagnosis.
Studies have found that the disease may also have long-term psychological complications. It is reported that 23% of patients suffer from anxiety or depression.
Researchers say that patients with more serious illnesses often continue to show X-ray damage to the lungs.
“Our analysis shows that most patients will at least still be infected with the virus after discharge, and emphasize the need for post-discharge care, especially for those with serious infections. Our work also emphasizes the need for such treatment Importance. The statement said: “We need to conduct longer follow-up studies in a larger population to understand the full impact of Covid-19 on people. “
Long-term health effects of Covid-19
Scientists all over the world are studying the long-term effects of this virus, often referred to as “long-term Covid” symptoms.
“Most people with Covid-19 can recover and return to normal health, but some patients’ symptoms may last for weeks or even months after the acute illness recovers. Even those who are not hospitalized and have mild illnesses, You will also experience persistent or late symptoms,” said the US Centers for Disease Control and Prevention.
The author said, but this Chinese study is the largest and the longest follow-up study to study the long-term impact on discharged patients.
The median age of the patients in the study was 57 years old. They were all discharged from Wuhan Jinyintan Hospital from January 7 to May 29, 2020. This hospital is a designated facility for Covid-19 hospitals and will treat the world since December 2019 The first case of a person suffering from this disease.
After excluding deaths, those who were unable to participate due to severe mental or physical conditions, and who refused to participate, the study included a total of 70% of all Covid-19 patients during the period.
All participants received a series of questionnaire assessments to assess symptoms. The study also stated that they also underwent a physical examination, a six-minute walk test and a blood test.
Unexpectedly, 13% of patients who did not develop acute kidney injury during hospitalization showed signs of renal failure.
However, according to Chinese researchers, the findings regarding fatigue, trouble sleeping, anxiety or depression are consistent with previous studies, which were related to severe acute respiratory syndrome (SARS) caused by coronavirus in 2003 and 2004. Patient research.
The researchers said that follow-up studies of SARS survivors showed that 40% of patients developed chronic fatigue symptoms more than three years after infection.
Researchers from the Institute of Pharmacology pointed out in their comments that another study showed that 38% of SARS survivors had evidence of lung injury 15 years later.
Increasing coronavirus outbreak
In March, China was infected with the coronavirus for the first time in Wuhan, and since then has quickly stopped sporadic endemic outbreaks.
But it is now facing the worst coronavirus outbreak in the northern province of Hebei in the lunar months. The capital of Hebei Province surrounds the capital, Beijing, just a few weeks before the Lunar New Year, which is the most important period of Chinese family reunion.
Shijiazhuang, the provincial capital and epicenter of the epidemic, was strictly blocked last week. As major highways are blocked, train and bus stations are closed, and flights are cancelled, residents are forbidden to leave the city.
