A study carried out by researchers from the University of Capital Medicine and other scientific institutions of the Chinese country published in The Lancet has resolved that, Of the more than 1,700 coronavirus patients used in the analysis, 76% had symptoms months after being discharged.
These sequelae could last, according to the study, for at least six months. The main post-illness side effects are fatigue and sleeping difficulties, which appeared in 63% and 26% of the cases analyzed. In addition, there would also be psychological complications after overcoming COVID-19, since 23% of the people studied would have anxiety or depression. Also, of course, patients who have had lung conditions continue to show damage to them, their X-rays show.
For all this, the researchers who have done the largest study to date of all who have tried to clarify post-disease effects They insist on the importance of accurately monitoring patients who have overcome severe COVID-19 illness to avoid serious health problems.
“Thanks to these studies we are beginning to understand some long-term effects in a completely new disease.”said Dr. Bin Cao, a worker at the China-Japan Friendship Hospital of the Capital Medicine University and director of the study.
Participants in the study
The patients analyzed had an average age of 57 years and were admitted to the Jinyintan Hospital in Wuhan, the center designated by the authorities to treat people infected with coronavirus. 70% of all patients who were discharged from the hospital have been included in the work.
The study collected some questionnaires with questions about the symptoms they presented, physical examinations and blood tests, as explained by the writing published in the prestigious scientific journal.
However, Workers of the Institute for Pharmacological Research in Bergamo (Italy) highlighted in a comment attached to the publication the importance of “interpreting the data with caution”as the way in which the data had been quantified was not entirely relevant. Further, they provide the results of other studies that differ in some aspect with the research carried out in the city that was the focus of the disease.
Main long-term sequelae
The main symptoms suffered by patients who have already overcome the coronavirus, as stated by the United States Center for Disease Control and Prevention (CDC), are fatigue, shortness of breath, cough, joint pain, and chest pain. There are also, although to a lesser extent, “mental fog”, depression and headaches.
The majority of patients recover their normal health, according to the American organization. However, there are patients who maintain their symptoms months after the disease. This happens to a greater extent to patients who have developed a serious condition, but it also happens to some with few ailments during the course of COVID-19.
The broadcast in Wuhan lasted until May
Another study conducted by workers from Wuhan University and published in Plos Neglected Tropical Diseases ensures that the disease, despite the fact that “it was labeled as under control by the local authorities in April”, was being transmitted through asymptomatic patients until well into May.
0.46% of the 60,107 people analyzed, who did not have any symptoms compatible with the disease, tested positive for IgM antibodies. These antibodies suggest that the patient has recently overcome COVID-19 or is suffering from it.
“The data we have obtained indicates that thousands of people were asymptomatic carriers of the virus between March and May, while the institutions did not report any clinical case of coronavirus”, finish the job.
