The sequelae of the new crown has attracted more and more attention. Many latest research results point out that the possibility of sequelae is related to the severity of the infection of the participants. , asymptomatic infected person, will not have persistent sequelae of the new crown.
" Asymptomatic infected people will not have persistent new crown sequelae "
On October 12, researchers from the University of Glasgow, UK published a research paper titled "Outcomes among confirmed cases and a matched comparison group in the Long-COVID in Scotland study" in the journal Nature Communications. This study is one of the largest studies on sequelae to date.
study shows that asymptomatic infected people will not have persistent sequelae of COVID-19, and vaccination before infection can reduce the risk of certain sequelae.
Researchers said the possibility of sequelae was related to the severity of the infection in the participants. Although most people will recover quickly and completely after infection, almost half of the infected people will still experience persistent symptoms.
Among the symptomatic infected people, 48% of the infected people still have sequelae within 6 to 18 months after infection, including 42% of the infected people only partially recovered, and 6% of the infected people have not recovered. Compared with the never-infected group, infected people were almost nine times more likely to lose their sense of smell, six times more at risk of losing their sense of taste, and three times more at risk of dyspnea.
In addition, the study found that vaccinated people are unlikely to report persistent sequelae, which mainly occur in hospitalized severely ill patients, including those with advanced age and underlying diseases①.
The best way to deal with the "long-term COVID-19" is to avoid infection
On October 12, the British " Guardian " published a signed article by WHO Director-General Tedros Adhanom Adhanom Ghebreyesus . Tedros proposed "five key elements" to deal with the "long-term COVID-19". This includes using first-hand knowledge of patients and medical staff to formulate more effective policies, improving information sharing among countries to quickly narrow the global knowledge gap, developing better treatment methods and clinical management, and promoting multidisciplinary care for patients.
Tedros stressed that avoiding infection is the best way for people to prevent the "new crown".
Wu Zunyou: The risk of sequelae of new coronavirus infections is much lower than that of unvaccinated people
"The sequelae of new coronavirus is also known as long-term symptoms of new coronavirus, which is common in severe cases, but can also occur in mild cases. Generally speaking, people who have been vaccinated have a risk of sequelae of new coronavirus infection , , and those who have been vaccinated are much lower than those who have not been vaccinated." On October 13, at the press conference of the State Council Joint Prevention and Control Mechanism, Wu Zunyou, chief epidemiology expert of the Chinese Center for Disease Control and Prevention, said.
The sequelae of the new crown can last for weeks, months or even longer. According to global research results, health problems with a wide range of health problems, including fatigue or fatigue, thinking disorders or inability to concentrate, shortness of breath or difficulty, headache, dizziness, accelerated heartbeat, chest pain, cough, joint or muscle pain, depression or anxiety, fever, loss of smell or taste, etc. These symptoms can occur repeatedly and cannot be explained by other diagnoses.
