With the adjustment of epidemic prevention and control policies, some people are worried that the release of social control will lead to a large-scale epidemic of COVID-19. In this case, is there a great risk to people's life and work? How can we do a good job of self-protection?Or, as some say, just do nothing and "get infected early"?With these questions, the reporter interviewed the region's experts in the field of infectious diseases and public health.
"The Omicron variant has a low dose of infection, a strong infectivity, and hidden transmission. Asymptomatic or mild cases can move around in society and cause transmission if they are not detected. In addition, with the approaching of the Spring Festival and the frequent movement of people, the risk of being infected will indeed increase."Gong Rui, chief of the Ningxia Center for Disease Control and Prevention's infectious disease prevention and control department, said that the general public need not panic too much. The COVID-19 caused by the Omicron variant can be prevented and treated. Even if infected, most of them have no symptoms or mild symptoms, and they can even recover without special treatment.
Gong said that from the existing relevant literature research, compared with the original strain and Delta variant, the Omicron variant is more contagious, but the virulence is significantly reduced, and the proportion of severe cases or deaths is also significantly reduced.Because the invasion of Omicron variant to the lower respiratory tract is weakened, most of them are asymptomatic or mild after infection, and the symptoms of infected people are mainly manifested in the upper respiratory tract. The symptoms vary from person to person, such as fever, cough, sore throat, fatigue, etc., which is related to their own immunity, age, and underlying diseases. The symptoms are really similar to influenza, but the transmission speed is faster than influenza.
After three years of "living" with COVID-19, some prevention knowledge about the COVID-19 virus has become familiar to everyone.But in order to let everyone eliminate panic and overcome the virus with peace of mind, Gong Rui once again emphasized the four key points to prevent COVID-19:
The first is vaccination.Gong said vaccination against the novel coronavirus is still recognized globally as one of the effective ways to prevent the virus.In the absence of contraindicated symptoms, eligible residents, especially the elderly and other key groups, should complete the vaccination as soon as possible to effectively reduce the risk of severe disease.
Second, we must develop good hygiene habits.Wearing masks, washing hands frequently, frequent ventilation, and not gathering are still effective means to prevent respiratory diseases.
Third, it is to improve their own immunity through a variety of ways.Such as reasonable diet, moderate physical exercise, reduce staying up late, according to the weather moderate increase or decrease clothing, improve their immunity.Gong reminded residents, especially those with chronic underlying diseases, to adhere to medication according to the doctor's advice.
Fourth, if you have fever, sore throat, cough and other discomfort, be sure to do a good job of health monitoring or antigen self-test."When the positive is found to be asymptomatic or mild, the first choice is home isolation treatment, if the symptoms have not been relieved for two or three days, or it is important to go to the hospital in time.
