Zhang Wenhong revealed the latest prevention and control progress of Aomi Kerong
At 0:23 on December 17, Zhang Wenhong posted that the international Omilton epidemic situation was confusing, and China responded in an orderly manner.
He wrote on Weibo: "The present is the most difficult time in the world, and it is the most difficult time for human beings to fight against the virus. The WHO expert group meeting agreed that "there is a need to rely on the broad implementation of public health restrictions and the completion of enhanced vaccination of vaccines, especially the unvaccinated, to join the ranks of vaccinators to cope with the risk of widespread spread of the Omikeron variant".
As can be seen from who's expert consensus, China's dynamic zero-clearing strategy, known as PHSM (Public Health and Social Measures), has been widely adopted internationally for the current Opickron response.
"Dynamic zeroing" capability is the most critical public health strategy at present. Recently, there have been frequent sporadic and local outbreaks in Delta in the Yangtze River Delta, Pearl River Delta, and Northwest China, but China's dynamic zeroing strategy has been confirmed to be able to cope in about 4 weeks. Even shaoxing Shangyu, academician Li Lanjuan mentioned that all the current cases are in a very clear chain of transmission, we beat the virus is only time, no need to panic.
Behind all our current sacrifices and perseverance is the confidence of the country's scientific and technological forces to persevere. Whether it is vaccines or drugs, we believe that we can support us through the most difficult times.
When Omi Kerong appeared, the Chinese team quickly made the following judgments and made corresponding coping strategies through the power of science and technology in about 2-3 weeks:
1, Beijing Xie Xiaoliang team: The Aomi Kerong variant escapes most of the current macromolecular antibody drugs, we will still face great challenges, but China's existing antibody drug research and development lines can still keep up with the mutation of the virus.
At present, China's macromolecular drugs that have been applied in emergency can still play a certain therapeutic effect. The National Center for Infectious Disease Medicine has also conducted a series of new antibody clinical trials, and at the same time targeted small molecule drugs, which are about to be gradually introduced in the second half of 2021, just like the who representative of yesterday's declaration, the world has the ability and confidence to control the new crown epidemic in 2022, and gradually return to normal life.
2. The hong Kong team's research on Omiljung is about to be officially published after the completion of the international peer review, and this study makes an important judgment: the virus has significantly evaded the 2-shot vaccination and can no longer block the spread of the virus. The level of intrabronchial replication of the new virus is significantly higher than that of Delta, and the rate of transmission is significantly increased on the basis of Delta. At present, without further tightening public health and social measures (PHSM) such as school closures, it will be difficult to stop the rapid spread of Aumicron and defeat Delta. At present, the United Kingdom has become the most rapidly rising country outside South Africa in the world.
But there is also good news, the Hong Kong team and the international team confirmed that the third dose of vaccination can still significantly reduce the incidence of symptomatic NEW crown pneumonia, but also help control the incidence of hospitalization and death. The WHO expert consensus on Omikron points out that all this still needs to be implemented in order to step up public health measures.
The fight against the epidemic has reached this juncture today, and whether China's experience is accepted or not, it has become a global common choice. Just recently, the UK has again taken public health and social measures such as school closures and has widely promoted the third dose of vaccination. All this proves that Aumikoron is not a live attenuated vaccine, and this is not the time to relax.
3. The Shanghai team and the Beijing team of the National Center for Infectious Diseases where I work have completed the third-party evaluation of the effect of homology and heterologous third injection vaccination in China, and the research results have been fully communicated with international vaccine experts, and will be officially announced after completing the international peer review, and the main research confirms that China's third injection can still retain the neutralizing effect on Omikeron and Delta, and has the potential to reduce the incidence of severe cases. China's follow-up third dose of optimized vaccination strategy is expected to be fully completed in 2021, and it will enter 2022 together with the international community. In what WHO calls the total control of COVID-19, people around the world will embrace ordinary and stable lives.
This winter and Spring Festival, we will spend the last cold winter with the international community, and we will eventually "lift the clouds and see the sky, and keep the clouds open to see the moon.".
Positive samples were detected at the residence of the confirmed case, and hand washing and ventilation are still important
On December 14, Guangzhou announced the discovery of the first case of Infection with the Aomi Kerong variant in Guangdong Province, and the patient was a citizen who had been isolated for observation after 14 days of entry and entered the home management stage in a closed loop. Disease control experts collected 132 environmental samples in the flow survey, 128 environmental samples tested negative, and 4 positives were found in the residence of the case.
On December 16, a cargo pilot in Guangzhou who had operated an international cargo flight was diagnosed. Disease control experts collected 312 environmental samples in the flow survey, 128 environmental samples tested negative, 1 positive was found in the case residence, and the rest of the results are to be released.
Why do positive samples frequently appear in the residence of confirmed cases? Where did these positive samples come from? How long does THE coronavirus survive after leaving the human body? What should ordinary citizens do? Nandu reporters synthesized the information of the two press conferences on the 14th and 16th, as well as the professional opinions of Cai Weiping, chief expert of the Eighth Affiliated City Hospital of Guangzhou Medical University, and Wang Ming, an expert with special allowances of the State Council and chief expert of the Guangzhou Preventive Medicine Association, and answered them one by one.
Zhujiang New Town, citizens wearing masks after work.
The main transmission route of the new crown virus pneumonia is respiratory droplet transmission and contact transmission, and the transmission routes such as aerosol and fecal-oral have yet to be further clarified. "People often don't wear masks when they return home, and it's not uncommon for virus-containing droplets to be brought out through sneezing, coughing, etc., and attached to the surface of commonly used utensils." Cai Weiping analyzed that the positive samples detected in the external environment in such patients' homes are not uncommon after the emergence of previous respiratory infectious disease outbreaks.
Limited by the current environmental sample detection methods, such environmental samples are often detected with virus fragments, which can neither confirm that the virus at the time of testing is dead, nor can it prove that it is alive. "More can only indicate that the virus has come, and the increase in positive samples in the external environment is closely related to the viral load and transmission capacity." Wang Ming said that whether it is Delta, which is still the mainstream strain, or Aomi Kerong, which has been detected in Guangzhou, its characteristics after infection have the characteristics of strong transmission ability.
The new coronavirus can remain active on the skin for 9 hours and survive longer on mobile phones
How long does the coronavirus survive after it leaves the human body? Wang Ming said that this is greatly related to the temperature and humidity at that time, and whether there was a systematic killing.
After the emergence of the new crown epidemic, Japanese public health experts published a study in an academic journal showing that the new crown virus can remain active on human skin for up to 9 hours, which is 5 times longer than the influenza virus. "Compared to the influenza A virus, the new crown virus can survive on human skin for 9 hours, which may increase the risk of contact transmission and thus exacerbate the spread of the epidemic. But (maintaining) hand hygiene reduces this risk. The study also suggests that both the coronavirus and the flu virus can lose their activity within 15 seconds if alcohol-based hand sanitizers are used.
Related studies have suggested that the new crown virus can survive on smooth surfaces such as glass (mobile phone screen) and stainless steel surfaces for a long time.
"In addition to objective influencing factors such as temperature, humidity, and whether there is disinfection, the smoothness of the surface of the object also determines the survival time of the virus after leaving the human body," Cai Weiping said.
Previously, some research reports disclosed that the new crown virus can survive on smooth surfaces such as glass (mobile phone screen) and stainless steel for up to 28 days. The coronavirus is characterized by its survival at lower temperatures and longer on non-porous or smooth surfaces (such as glass, stainless steel, and vinyl) than on porous, complex surfaces such as cotton.
In recent days of briefings, disease control experts and front-line epidemiologists have also conducted external environmental tests in public places, and the external environmental samples obtained are not positive. This also reveals some important information: the external environment is often ventilated and sunny. "Ventilation can dilute the virus, and ultraviolet rays in sunlight can kill the virus," the two experts told Nandu reporters, it is worth noting that past experience suggests that to reduce the spread of the new crown epidemic, it is also necessary to pay attention to the potential risks in the elevator. "It is recommended that in the future, after the elevator in the residential area is suspended, the gate is open and ventilated, rather than the door is closed," Cai Weiping said.
"In order to do a good job in the prevention and control of the new crown epidemic, we will recommend that citizens must do a good job of cleaning their homes, wear masks, ventilate frequently, pay attention to personal hygiene, and maintain social distancing." In fact, the discovery of positive samples in the homes of confirmed cases is a reminder that we can reduce transmission through these physical, non-drug means," Wang Ming said, although it is a cliché, but it is actually effective.
Wash your hands frequently and ventilate more immediately. Also, how long have you not washed your hands and washed your phone with disinfectant wipes?
