A new study in Wuhan shows that Covid symptoms may last at least 6 months



A study of more than 1,700 patients in Wuhan, where the pandemic originated in China, showed that 76% of patients developed symptoms at least one month after discharge.

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.

“Because Covid-1

9 is a new disease, we are just beginning to understand some of its long-term effects on patient health,” Dr. Cao Bin from China-Japan Friendship Hospital and Capital Medical University led the research team in a statement. .

“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.

The Centers for Disease Control and Prevention (CDC) lists fatigue, shortness of breath, cough, joint pain and chest pain as the most frequently reported long-term symptoms. Among long-distance transporters of the coronavirus, other problems have also appeared, such as thinking and concentration-known as “brain fog”, depression and headaches.

“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.

A study published in the British Medical Journal in August found that about 10% of patients suffered from Covid-19 for a long period of time, lasting more than 12 weeks.

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.

Wuhan Jinyintan Hospital is the first medical institution in the world designated to treat Covid-19 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.

Studies have shown that nearly one million people in Wuhan may suffer from Covid-19.Almost ten times the official figure
However, a team of researchers from the Bergamo Institute of Pharmacology in Italy did not participate in the study. They wrote in the accompanying commentary in The Lancet that the findings “must be interpreted with caution” because of the limitations of this method Sex it was measured. ”

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.

One year after Wuhan, China blocked another city of 11 million people to contain the coronavirus outbreak
Officials from Hebei Province said at a press conference on Sunday afternoon that last week, 13 million people in Shijiazhuang and Xingtai City were tested for the large-scale coronavirus and 364 positive cases were found.

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.

Within the city, public transportation and schools have been suspended, residential communities and villages have also been closed, and residents are required to stay at home for seven days after completing a coronavirus test.

According to data from the National Health Commission of China, 82 cases of locally transmitted Covid-19 were detected in Hebei Province on Sunday, of which 77 were reported in Shijiazhuang and 5 were reported in Xingtai.

In some cities in northern China, including Beijing, as well as Liaoning and Heilongjiang provinces, local coronavirus infections have also been reported.
In Beijing, an online taxi-hailing driver was found to be asymptomatic on Saturday, prompting the authorities to trace 144 passengers in the car. Starting Monday, all passengers must display a QR code from the Beijing Covid-19 Health app on their smartphones before they can take any taxi or ride-hailing service.
