Recently, the Chinese Center for Disease Control and Prevention issued a high-profile circular providing an in-depth analysis of the new crown epidemic situation between September 1 and September 30, 2023, including the source of the virus, the trend of the number of infected people, and corresponding countermeasures. The release of this circular has aroused widespread social concern in the context of the resurgence of the new crown virus.
The circular pointed out that the main reason for the resurgence of the new crown epidemic is the mutation of the virus. Through the results of genome sequencing, we learned that the dominant variant of the new coronavirus is currently B.1.1.7, and the number of infected cases of this variant has been on the rise. This variant has greater transmissibility and immune evasion, allowing the virus to spread faster and more insidiously.
The briefing also provides a detailed analysis of trends in the number of people infected with the new coronavirus. The reasons for the resurgence of the new coronavirus mainly include the increased transmissibility of variants and the arrival of winter. In winter, poor indoor ventilation increases the risk of virus transmission. The period from October to March is the peak period of the new crown, which exacerbates the spread of the epidemic.
For ordinary people, in the face of a new round of new crown virus threats, how to effectively take protective measures has become a top priority. Here are some key precautions, particularly when it comes to mask wearing and prevention of respiratory infections.
Correct selection and wearing of masks. When selecting a mask, a medical surgical mask or a medical protective mask (N95 mask) should be preferred and ensure that the mask completely covers the nose and mouth. When wearing, the upper edge of the mask should be close to the nose and the lower edge should fit the chin to ensure that the mask is completely sealed to the face.
When removing the mask, be sure to keep your hands clean and avoid touching the inside and outside of the mask to avoid cross-infection.
Contact sites should be cleaned and disinfected immediately after contact with others, especially with a known infected person, to reduce the risk of infection.
Regularly clean and disinfect surfaces of frequently touched items such as cell phones, doorknobs, tabletops, etc. to reduce the spread of viruses.
In public, practice safe distancing and avoid close contact with others, especially if you are not wearing a mask.
Try to avoid going to crowded places and avoid large gatherings or events.
This time, the pandemic is back, but we have also accumulated more experience and knowledge to deal with it. Following these simple precautions will not only help protect yourself, but also others and slow the spread of the epidemic. At this special moment, everyone should unite and work together to overcome the difficulties. Only then can we finally defeat this threat and face a healthier and safer future.
