A study of over 1,700 patients who underwenttreatment in the Chinese city of Wuhan, the initial epicenter of the pandemic, found that 76% of infected patients suffered from at least one symptom several months after being discharged from hospital. The findings revealed that even those who have had COVID-19 can suffer long-term health consequences from the fight against the coronavirus, which, according to the latest data, infects more than 90 million people worldwide. The largest study of its kind, published in the medical scientific journal The Lancet, found that fatigue and difficulty sleeping were the most common symptoms after COVID-19, with 63% and 26% of patients, respectively. In 23% of patients in the study, depression or anxiety developed within six months of discharge. We will talk about what other difficulties you may face while suffering a coronavirus infection in this article.
Long-term consequences of COVID-19
Because COVID-19 is a disease for humanitynew, researchers are just beginning to understand some of its long-term health effects. So, recently we talked about the fact that some patients do not recover their sense of smell (remember that anosmia is the loss of the ability to smell one of the symptoms of COVID-19). Now, the results of a large and so far one-of-a-kind study have shown that patients with more severe disease tended to show signs of lung damage on x-rays.
“The analysis shows that the majoritypatients face some of the effects of the virus after they recover. This emphasizes the need for care after discharge from hospital, especially for those who have had a severe illness. Our work also highlights the importance of longer-term follow-up studies in large populations. This is necessary to understand the full range of effects that COVID-19 can have on health, ”write the authors of the scientific work.
The "long term effects of covid" are strongare of concern to experts from the World Health Organization (WHO) and are under the scrutiny of scientists. Back in October last year, it became clear that COVID-19 is fraught with complications, and the harder a person has an infection, the longer the recovery takes. US Centers for Disease Control and Prevention (CDC) specialists list fatigue, shortness of breath, cough, joint pain and chest pain as the most frequently recordedlong-term symptoms. Other equally unpleasant consequences include difficulties with thinking and concentrating ("fog in the head"), depression and headache.

“While most of the people whoCOVID-19s recover and return to normal, with some patients experiencing health problems for weeks or even months after recovery. At the same time, complications are observed even in those patients who escaped hospitalization and suffered an infection easily, ”the CDC specialists note.
Average age of patients who tookParticipation in the study was 57 years old, all of them were discharged between January 7 and May 29, 2020 from Jinyintan Hospital in Wuhan, the institution that has treated the world's first people to contract the disease since December 2019. In total, 70% of all discharged patients during the specified period were included in the study (after excluding the deceased, those who could not participate due to severe mental or physical conditions, and those who refused to participate). All subjects were interviewed using a series of symptom assessment questionnaires. They also underwent medical examinations and blood tests. Surprisingly, 13% of patients who did not appear to have had kidney disease before hospitalization showed signs of renal dysfunction.
However, scientists from the Institute of Pharmacologicalstudies in Bergamo, Italy that were not involved in the study wrote in an accompanying commentary in The Lancet that the results "must be interpreted with caution" as there are limitations to how they were measured. "
It is interesting that data on fatigue, difficulties withsleep, anxiety, or depression are consistent with previous studies of patients with severe acute respiratory syndrome (SARS) in 2003 and 2004. A subsequent study of those who had recovered from the "younger brother" COVID-19 showed that 40% of patients persisted symptoms of chronic fatigue more than three years after infection. Another study found that 38% of those who had SARS there were signs of lung damage 15 years later.
Life after COVID-19
According to CNN, the new study followsin a separate study by researchers from King's College London, UK at the end of October 2020. At the time, researchers analyzed the symptoms of 4182 coronavirus patients who registered their illness with the COVID symptom study app. The researchers noted that 558 patients had symptoms for longer than 28 days, while 189 people had health problems for more than eight weeks, while 95 patients reported that problems persisted for longer than 12 weeks.

The researchers also found that more often than notpatients reported fatigue, headache, dyspnea, and anosmia, and were more common in older patients, women, and overweight patients. As for another possible long-term side effect of COVID, some of those who have had covid have experienced a distorted sense of smell, describing an unpleasant fishy or sulfur smell.
