A new confirmed case of new coronary pneumonia was added on March 21 in Furong District, Changsha City. According to the investigation, the confirmed case Jiang Moumou had a short time and space intersection with Xia Moumou (confirmed on March 17th), a long-term confirmed case from other places, in an outdoor public place on March 16. Xia Moumou and Jiang Moumou Neither of them wore a mask, and the two walked towards each other and passed each other, about 0.5 meters apart.
Can I spread about 0.5 meters apart without wearing a mask? And is it outdoors?
Experts from the Furong District Center for Disease Control and Prevention said that the answer is yes. Xia was diagnosed on March 17. At that time, he was in the detoxification period. During the process of coughing, spitting, or sneezing, the body is removed from the body. The sprayed droplets can be large or small. Large droplets will directly settle to the ground, while some small droplets will be suspended in the air, which can be spread by others when inhaled. At this time, Jiang Moumou did not wear a mask and was infected.
Experts from the Furong District Center for Disease Control and Prevention said that no matter how the new coronavirus mutates, it is still spread through droplets and contact. The highest and simplest means of protection.
Furong District CDC reminds:
Epidemic prevention and control is everyone’s responsibility. Everyone is the first responsible person for their own health. In daily life, you must adhere to wearing masks in a standardized manner, wash your hands frequently, maintain a social distance of 1 meter in public places, consciously take personal protection, and actively cooperate with “epidemic prevention” places when entering public places. code”, and actively cooperate with epidemic prevention and control measures. Minimize crowding.
Is the new crown a big flu? The latest interpretation of experts
According to CCTV reports, at present, some members of the public and scholars have proposed that the new crown caused by the Omicron variant is equivalent to a “big flu”. Liang Wannian, head of the expert group of the National Health Commission’s Epidemic Response and Disposal Leading Group, said:
“It is too early to draw this conclusion. Because its transmissibility and harm to human health are higher than ordinary influenza. It may be that for a certain individual, the probability of severe illness after infection is decreasing; Look, it spreads quickly, and the infection rate is high in a short period of time. The absolute number of infected people will be large, and the absolute number of severe cases and deaths will be high. This is a great harm to a society and a country. ”
Why can’t China cancel the epidemic prevention measures like other countries?
Liang Wannian said: The protection strategies and specific measures adopted by various countries are based on their prevention and control concepts. China’s prevention and control philosophy is “people first, life first”. Since the outbreak of the epidemic, China has been insisting on dynamic clearing, and constantly optimizing prevention and control measures. It can be said that we have protected the people from the so-called herd immunity and natural immunity.
We mainly build immune barriers through active vaccine immunization to enhance resistance. But from an international point of view, some countries choose to “lie down” because two kinds of immunity coexist. One is through natural immunity, that is, group infection. It can be said that a considerable proportion of the people have been infected with the new crown virus, and the other is through active immunity. vaccine immunization.
In this case, if China also chooses to “lie down” and does not insist on dynamic clearing, especially the current vaccination rate, especially the vaccination rate of the whole course and booster needle is not completely high enough to constitute a solid The immune barrier is bound to make a large group of elderly, vulnerable and vulnerable people susceptible to infection. In this case, we must adhere to the policy of dynamic clearing and keep our strategies and measures unswerving. This is also a time window for us. If we strengthen vaccination and speed up scientific and technological research and development, including drug research and development, vaccine research and development, I think we may also have a chance, maybe Omicron has changed again, become more mild, and the transmission rate and disease rate are lower. , that’s our best chance. Therefore, at this stage, we insist that the general strategy and general policy remain unchanged, which should be the best choice, and it is also in line with China’s anti-epidemic reality.
