Recently, the domestic epidemic prevention and control situation is still severe and complex. Is Omi kerong a "big flu"? Will flying fibs lead to the spread of the new crown virus? How to do a good job of personal protection? Relevant experts of the Joint Prevention and Control Mechanism of the State Council gave authoritative answers.

Omikron is not a "big flu"
Experts from the Joint Prevention and Control Mechanism of the State Council to Jilin Medical Treatment Group analyzed that Aomi Kerong has a serious threat to special groups such as elderly patients and patients with serious underlying diseases. Omikeron is by no means a "big flu."
Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, said that the characteristics of the Olmi kerong variant strain are first of all highly contagious, second, the speed of transmission, and third, the transmission process is very hidden.
"The decline in the virulence of the Olmikeron strain is relative to the previous strain, and it is still more harmful than influenza, especially in the elderly who have not been vaccinated or have not been fully vaccinated." Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, said.
Wang Guiqiang introduced that at present, the Omicron strain circulating in the mainland has a high proportion of asymptomatic infections and mild cases from the overall point of view. First, because the virulence of the Omiljung strain itself has decreased relatively, the upper respiratory tract infection is the mainstay, the lower respiratory tract infection is relatively small, and the incidence of pneumonia is relatively low. Second, because under the background of current vaccination, the proportion of severe cases in the vaccinated population is obviously low. Third, because of active nucleic acid screening, many patients are found during the incubation period, so the proportion of asymptomatic infected people is relatively high.
Liang Wannian, head of the expert group of the National Health Commission's leading group for the response to the new crown pneumonia epidemic, believes that Aomi Kerong is not the flu. We must unify our understanding and abandon the "big flu theory."

Will flying fibs lead to the spread of the new crown virus?
Everywhere is about to enter the flying period, will the willow fluttering with the wind have the risk of spreading the new crown virus?
Wu Zunyou, chief expert of epidemiology of the Chinese Center for Disease Control and Prevention, said that the new crown virus generally does not transmit directly from an infected person to a healthy person in the form of a free virus, and the new crown virus usually uses droplets as a carrier to adsorb on the surface of tiny droplet particles, patients discharge droplets by coughing and sneezing, and the virus adsorbs on the particles with droplets discharged. Droplets are generally smaller and should travel at a distance of 1 to 2 meters.
Wu Zunyou said that in the past two years of research, no fly can adsorb the virus, on the other hand, there is no report on the infection caused by fly flop so far.

Insist on personal protection
Wu Zunyou introduced that under normal circumstances, respiratory infectious diseases are mainly transmitted through close droplets, but also through the hands to contact the surface of contaminated objects, the hands without disinfection or cleaning and contact with the mouth, nose, eyes and other mucosal parts, it is easy to cause infection.
Wu Zunyou suggested that in daily life, express packages should be disinfected before opening. Usually, we must pay attention to hand hygiene and hand cleanliness, and adhering to hand hygiene can reduce the risk of contracting the new crown virus due to contact with contaminated surfaces.
If a person has been infected with Delta strains or TheOmexon strains, do they still need to pay attention to personal protection?
"Without taking any precautions, it is still possible to be re-infected if you encounter an infected person." Wu Zunyou said that the mutation of the new crown virus has been happening continuously, no matter how it changes, we can respond to changes and reduce the risk of personal infection with the same change - mainly to implement protective measures, including wearing masks, hand hygiene, social distancing, etc., and to actively vaccinate against the new crown.
