How to strengthen "external defense input" in the face of virus variation? Can I still travel on New Year's Day?

Medical network December 22 in the face of virus mutation How can China strengthen the "foreign defense input"? Can I still travel on New Year's Day? China's CDC responded → new coronavirus recently appeared in the United Kingdom on December 19, the British government confirmed the emergence of new coronavirus variants.
20, London and the surrounding areas, from the level of three levels of prevention and control to the highest level of four.
china's epidemic prevention and control situation is facing any new changes as the country enters winter? New Year's Day is approaching, the Spring Festival is coming, the new large-scale movement of personnel, but also will bring about the epidemic prevention and control of what impact? Bai Wei, a reporter for News 1 and 1, and Feng Zijian, deputy director of the China Center for Disease Control and Prevention, are jointly concerned about the new coronavirus mutation.
information can be confirmed about new coronavirus mutations in the UK? On the official website of the Department of Health and Social Care, Chris Whitty, the UK's chief medical officer, made a brief statement about the mutated new coronavirus, the first to admit that there had been a new variant of the virus in the UK.
spread rapidly to the UK, starting in the south-east of England, and it is not clear how fast it will spread.
there is no scientific evidence that the mutated new coronavirus will have a higher fatality rate and have an impact on the effectiveness of the vaccine, which will take time and scientists to prove further.
uk is in active contact with WHO to keep a close eye on changes in the UK outbreak in order to take more urgent action.
the BBC in an article on the morning of the 21st, the British government admitted that the new coronavirus after the mutation, the rate of transmission increased by 70%. In a recent article in the Financial Times,
noted that "the fact that the variant is more contagious is that it caused 28 per cent of infections in London between september 20 and early November;
is it true that the media used the term "escape from London" to describe the current state of the British people? The British government wants to declare the city closed, London as a commuter cosmopolitan city, many people are working here, do not live here, the closure means that can not return home, so to rush back before the weekend.
the annual traditional holiday Christmas is coming, everyone rushed home to reunite with their loved ones, the mood is very urgent.
just announced the virus mutation, the rate of transmission is very fast, which undoubtedly caused a certain degree of panic to the public psychology.
I understand that nearly 30 countries and regions around the world have stopped traveling with the UK.
the latest news is that the European Union is in urgent negotiations, the French government said it will come up with a deal to resume traffic with the UK as soon as possible.
the spread rate of the new coronavirus virus increased by 70%, the data is pushed by the model performance, accurate? The ability to spread does increase, and the cell regions that mutate at the same time are worrying.
, deputy director of the China Center for Disease Control and Prevention: This result is indeed a mathematical model, because there is no way to actually measure in the population, can only be used to speculate on the model.
but it also gives us an important reminder that there are signs of increased transmission of the mutated new coronavirus in the population, as well as some actual data.
For example, in the last seven or eight weeks, the incidence rate in the UK, particularly in the south-central part of the country, has increased about fourfold a week, and the proportion of new variants has increased significantly, which in one respect is evidence of the increased ability of the mutant new coronavirus to spread.
In addition, the virus is now found to mutate mainly on its hedgehog protein, which is important because it is a very important site, region, especially in the subject binding area (RBD) when the virus invades the human body and binds to human cells, which is even more worrying.
new coronavirus: pathogenicity and viral toxicity are currently not shown to improve, and it remains to be seen whether vaccine protection has an impact.
China CDC Deputy Director Feng Zijian: pathogenic mainly depends on how many people infected, how many of them become ill, symptoms, this ratio can reflect its pathogenicity, now it seems that the mutated new coronavirus does not seem to show any signs of improved pathogenicity.
, on the contrary, saw another phenomenon, the proportion of asymptomatic infections is on the rise, if so, but the pathogenicity is decreasing.
addition, there is no increase in the toxicity of the virus, the toxicity is reflected in the fatality rate or fatality rate, there is currently no observed increase in the fatality rate, which is a basic understanding of it.
is there cross-protection between antibodies produced by current vaccines, protection and mutated viruses, or is there any protection against previously infected immunity? No further data are available in this regard, and further observations are needed to further validate the laboratory, including animal experiments.
Cdc is paying close attention to and studying the risk of transmission of the mutant new coronavirus, whether it will become a mainstream strain in the future, how to do a good job of prevention and other issues.
, Deputy Director of the China Center for Disease Control and Prevention: The National Center for Disease Control and Prevention is very concerned about the spread of viruses and mutations, including changes in the characteristics of transmission, all information we are highly concerned about.
With regard to what is happening in the UK, we have been following the analysis, disclosure and presentation of data on the mutant virus by Public Health England and scientific institutions, as well as by some of the world's major public health organisations and international professional bodies.
At the same time, for the virus mutation situation, we also use the international gene database to do some analysis, do some research, its transmission risk, the global further spread of the situation, including whether the future will become mainstream strains and so on, including what measures we can take to do a good job of prevention, have been carefully studied and considered.
At present, China has not found a mutant new coronavirus input Situation China CDC Deputy Director Feng Zijian: From the virus sequence obtained in our country, whether it is imported personnel, goods or cold chain products, from various ways to obtain the virus, have not found that China has a variant virus input.
, of course, we will continue to be highly concerned and closely monitor the activity of the virus.
the emergence of a new coronavirus, how can China strengthen the work of "foreign defense input"? Feng Zijian, deputy director of the China Center for Disease Control and Prevention: On the one hand, we should pay close attention to the spread of mutant viruses in the United Kingdom and Europe, and even around the world;
the measures taken by our country over the years of "external anti-input, internal anti-rebound" can be very effective in preventing overseas virus importation, especially in dealing with the further spread caused by the importation of viruses.
we are conducting research and assessing what needs to be done and what measures will be taken to address the mutant virus in the UK this time.
the emergence of a new coronavirus, in the overseas frozen chain food prevention, what needs to be done? Feng Zijian, Deputy Director of the China Center for Disease Control and Prevention: Because of the recent outbreak of transmission caused by pollution from imported goods and international means of transport, we have strengthened many prevention and control measures in this regard, including quarantine inspection after entry, including disinfection of products, the use of special storage conditions for imported goods, protection of personnel exposed to imported goods, imported means of transport, and strengthening their nucleic acid testing.
measures have been strengthened and have worked well.
do you think of the phenomenon of "environmental transmission"? It is still an example, but precautions should be strengthened.
, deputy director of the China Center for Disease Control and Prevention: Environmental infection may be a very important problem for the virus, but at present in China found a case, is a very rare phenomenon.
, however, prevention should be strengthened in this regard, especially for the feces of infected persons, the management of sewage systems and the implementation of sanitary measures, which are very important.
you still travel on New Year's Day? OK! But still do a good job of protection.
Deputy Director of the China Center for Disease Control and Prevention Feng Zijian: Can travel, because China's overall situation is very safe.
, but still observe to maintain interpersonal distance, wear masks, strengthen personal hygiene, while for the elderly, chronically ill people to minimize travel.
