At present, novel coronavirus and his recombinant mutant strains are still raging all over the world. Over the past few days, the World Health Organization and multinational public health experts have repeatedly stressedThe pandemic of COVID-19 is far from over. It is expected that novel coronavirus will continue to evolve and people will see more mutated strains appear.
It also said that the uncertainty of epidemic prevention and control is still high and that there is a great risk of relaxing social restrictions prematurely.However, some countries and regions have cancelled epidemic prevention measures and adopted the mode of "coexisting with viruses".
At present,The sequelae of this model have emerged one after another.In some countries and regions, the number of cases has soared, the death toll has risen, and the health care system is under great pressure.
Since XE (the recombination of Omicron BA.1 and BA.2) was found in the UK, there have been many mutants of novel coronavirus, such as XL, XF, XD and so on (XD and XF are the recombination of Delta and Omicron BA.1).
Recently, there was the first case of infection with recombinant COVID-19 strain XL in South Korea, followed by 2 cases of COVID-19 recombinant strain XE and 1 case of XM.As South Korea lifted most of its epidemic restrictions, the number of new cases in the country jumped to more than 80,000 a day.
According to the report of the Korean Agency for Disease Control and Prevention on the 26thThere are 80361 new cases of COVID-19 in a single day in the country.The number of cases increased significantly from 34370 the day before, bringing the cumulative number of cases to more than 17 million.
Furthermore,The Spanish Health Alert and Emergency Coordination Centre reported the sequence corresponding to the recombinant XE system.It is proved that the cases caused by XE mutants have begun to spread in Spain. And the Omicron variant accounted for 99.3% of the randomly sequenced samples.
The Ministry of Health of New Zealand also announced that the country has found its first case of XE infection with recombinant COVID-19 strain..
China has also been hit. RecentlyA press conference on epidemic prevention and control was held in Yantai City, Shandong Province, saying that the epidemic was caused by Omicron BA.2 mutant infection.It is more contagious and has a shorter incubation period. And the epidemic shows obvious spatial aggregation, which may have been hidden and spread for some time.
The U.S. Centers for Disease Control and Prevention (CDC) saidOmicron BA.2.12.1 mutants are becoming more and more common in the United States.In new York, new jersey and Connecticut, the Omicron BA.2.12.1 mutant has accounted for 52.3% of new COVID-19 cases.
The World Health Organization advises countries to be ready to strengthen public health responses to curb the spread of the virus.
However,Because some countries and regions are unable to find an ideal strategy for epidemic prevention, coupled with the mentality of anti-epidemic fatigue, facing downward economic pressure, and the fluke mentality of "the pathogenicity of the Omicron strain is weak," management and control measures such as mouth mask commands, isolating infected people, and tracking secret contacts have been cancelled one after another, and basically no prevention and control measures have been taken except for strengthening vaccination.
Facts soon proved that "lying flat" is not an option for epidemic prevention. "lying flat" is followed by a surge in the number of cases and a high number of deaths.According to Worldometer statisticsThe cumulative number of confirmed cases of COVID-19 worldwide has exceeded 510 million.
In the United States, for example, due to the cancellation of mask orders and the closure of COVID-19 surveillance sites, the number of confirmed cases in COVID-19 in many states of the United States rose in April. USA Today's analysis of data from the U.S. Department of Health and Human Services showsIn 32 states, there were more confirmed cases of COVID-19 in the last week than in the previous week.Hospital intensive care departments in 15 states have admitted more confirmed cases.
At the same time, the ups and downs of the epidemic situation brought about by "lying flat" in some western countries have brought great pressure on the vast number of developing countries to fight the epidemic and buried more public health risks.
Announced the implementation of the "coexistence with COVID-19" plan at the end of February.The United KingdomFor example, itsThe health care system is under unprecedented pressure.The new high infection level and the high rate of sick leave among health care workers have put the British health care system in a difficult state.It is difficult for not only hospitals, but also schools and enterprises to maintain normal operation. "1/10 of people are sick."
To thisStephen Griffin, a virologist at the University of Leeds School of Medicine in the UK, criticized that the British government's cancellation of prevention and control measures and the launch of the "coexistence with COVID-19" plan were tantamount to ignoring novel coronavirus's continued and rapid spread.He urged countries that chose to "lie flat" to "rebuild public health measures rather than leaving the public at their own risk".
A number of public health experts around the world also warnedNovel coronavirus is still mutating, the epidemic situation is uncertain, and there is a great risk of relaxing social restrictions too early.
On April 26th local time, the World Health Organization urged countries to maintain surveillance of novel coronavirus infected people. World Health Organization (WHO) said: "As many countries reduce testing, we receive less and less information about virus transmission and sequencing. This makes it more and more difficult for us to see the spread and evolution of the new crown virus."
Richard Hatchett, chief executive of the Alliance for innovative Epidemiology, said: "as long as the spread of the virus is high and there are unprotected groups, it will create an environment in which the virus is likely to mutate. Viruses continue to evolve, and unpredictable viruses can cause pandemics at any time. "
