One of the biggest mysteries of COVID-19 isHow long does its effects focus onConsidering that the virus has only circulated widely for less than two years. But over time, scientists and medical experts continue to conduct research on Long Covid, some emerging clear trends. A recent study published inThe lancetOutside Wuhan, China, the epicenter of the pandemic first, sought to compare the symptoms in 1,276 cavident patients hospitalized six months after their way to what they feltA year after getting Covid. In the greatest study of its kind so far, the researchers have found that many people continued not only to suffer COVID effects a year later, but two particular symptoms were more common than they were The six-month note.

The study showed that 68% of hospitalized cavidant patients always knew at least one symptom after six months. This rate fell to only about half a year after the infection, which means that half of hospitalized covidant patients found themselves with the majority of their symptoms 12 months later. Among those who always meet theCOVID effects after a yearThe most common symptoms were fatigue and muscle weakness, of which 20% of patients reported from 52% to six months. Many other symptoms have also improved for hospitalized patients between six months and 12 months after infection, researchers have found: 17% still lived sleep difficulties, from 27% to six months; 11% reported hair loss by 22%; And by far, fewer patients said they have always had trouble soaking with odor disorders, the symptom of covidation reveals from 11% to 4%.

But two symptoms consolidated that the tendency to become less commonly reported to the one-year mark compared to six months. The proportion of patients with dyspnea or laborious breathing, slightly increased by 26% to 30%. In addition, more patients had an anxiety or depression a year later than expected at six months, or 26% versus 23%.

"TheEffect of Long Covid on Mental Health guarantees a more in-depth and long-term investigation, "said the authors in an accompanying editorialThe lancet. "The proportion of CVIV-19 survivors with anxiety or depression has increased slightly between 6 months and 12 months and the proportion was much larger in COVID-19 survivors than in controls."

CoauthorXiaoying GU, MD, from the China-Japan Friendship Hospital, said that more research should be made to understandWhy were the psychiatric symptoms more common? A year later, compared to six months. "These could be caused by a biological process related to the virus infection itself, or the immune response of the body", said Gu in a statement, via MedPage today. "Or they could be linked to a reduction in social contact, loneliness, incomplete recovery of physical health or loss of employment related to the disease."

Although it is a little while before these questions are answered, the researchers note in their editorial that it is clearcap Causes conflicts of individuals for several months after their body has identified the infection itself.

"Symptoms such as persistent fatigue, shortness of breath, brain fog and depression could debilitate several million people on a global scale. Yet we know very little about the disease", the authors write in the Long Covid study. In their editorial, they point out that "health care providers must recognize and validate the toll of lifelong-lived persistent symptoms on patients and health systems need to be prepared to achieve individualized and patient-oriented objectives, with a patient. Workforce trained appropriately involving physical, cognitive, social and professional elements. "

The authors also emphasize that Long Covid is not just a patient problem, but a question that will also continue to affect society in general. "The effect on society, the increase in the burden of health care and economic losses and productivity, is substantial. Long Covid is a modern medical challenge of the first order," they write in the study, adding In their editorial according to which "the scientist and medical communities need to collaborate to explore the mechanism and pathogenesis of Long Covid, consider the burdens of global and regional disease, which is the most at risk, understand how vaccines can affect the disease and find effective treatments.
