(Fighting against New Coronary Pneumonia) Officials talk about the "human-to-human transmission" of the virus: there is insufficient evidence of domestic personnel infection caused by non-refrigerated imported items

  China News Service, Beijing, January 22 (Reporter Ying Ni) The recent local epidemics in Beijing, Shenzhen and other places have the possibility of "infection caused by express items", arousing all parties' attention to preventing the "human-to-human" of the new coronavirus.

On the 22nd, He Qinghua, a first-level inspector of the CDC of China's National Health Commission, responded at a press conference held by the Joint Prevention and Control Mechanism of the State Council.

  "Experts' judgment and analysis believe that at present, there is insufficient evidence that non-refrigerated imported items cause domestic personnel to be infected, and further research is needed. The risk of epidemic prevention and control needs to be closely observed and evaluated." He Qinghua said.

  He further pointed out that from the perspective of global research and prevention and control practices, the new coronavirus is infected through the respiratory tract, mainly through close contact between people.

Therefore, the current focus of epidemic prevention and control is still to prevent "human-to-human transmission" of the virus.

At the strategic level, all localities should adhere to the general strategy of "foreign defense input, internal defense rebound" and the general policy of "dynamic clearing"; at the tactical level, it is necessary to not only grasp key areas and key links, but also strictly implement a series of daily defenses. control measures.

  "More than a year of prevention and control practice has proved that my country has better balanced the relationship between epidemic prevention and control and social and economic development, and my country has become the only major economy in the world with positive economic growth." At the meeting, the National Health Commission Liang Wannian, head of the expert group of the Leading Group for Epidemic Response and Disposal, said that facts have proved that China's prevention and control strategies and measures are effective and in line with China's actual conditions.

  Liang Wannian said that the new crown epidemic will have a certain impact on the economy and society of all countries in the world, and different prevention and control strategies and measures have differences in reducing and controlling these negative impacts.

He emphasized that it is necessary to evaluate the cost and effect of prevention and control from the dimensions of prevention and control cost and prevention and control effect, cost efficiency, cost utility, and cost benefit.

  Regarding the statement "whether China does not need to take strict prevention and control measures", Liang Wannian pointed out that from a global perspective, the new crown epidemic is still in the acute stage of a pandemic, and there is still great uncertainty in the future development direction of the epidemic.

For example, he said, people are not very clear about the harmfulness of the Omicron variant, such as its pathogenic ability to different populations and the sequelae caused by the disease.

In addition, population vaccination against Covid-19 has not yet reached a level sufficient to establish a strong immune barrier.

The prevention and control practice of many countries has also proved that prematurely unblocking can easily lead to a rebound of the epidemic, severe cases and increased deaths.

  Liang Wannian said that considering the above factors, China's current prevention and control measures and strategies are effective in dealing with mutant strains in the context of the new crown pandemic.

"It can keep our country in a relatively safe state and avoid large-scale cases," he said, even if there are local clusters or sporadic cases, "basically, it can be controlled within one to two maximum incubation periods. ".
