Xinhua News Agency, Beijing, January 20 Title: Increasing risk of hidden transmission How to "block" Omi kerong?

Xinhua News Agency

At present, Tianjin, Anyang, Dalian, Shanghai, Zhuhai, Beijing and other places have reported local cases of Infection of Aomi Kerong. Judging from public reports, the symptoms of the infected people in Aomi Kerong are relatively mild, but the spread is fast and highly contagious, and some epidemics are detected after a long period of hidden transmission.

How can local outbreaks in local areas prevent spillovers? How to better guard the external defense input gate? How to implement various measures faster and outperform Omi kerong? The reporter interviewed and sorted out the latest situation.

Anti-spillage Race against Opmi kerong

As of 24:00 on January 18, a total of 326 confirmed cases and 22 cases of local asymptomatic infection were reported in Tianjin, of which 10 cases turned into confirmed cases.

In view of the characteristics of the fast spread of Aomi Kerong and the strong concealment, after the outbreak of the epidemic, the Tianjin Municipal Epidemic Prevention and Control Command timely delineated the scope of the sealing and control area, the control area and the prevention area, and advocated that the masses should not leave Tianjin unless necessary.

Gu Qing, deputy secretary general of the Tianjin Municipal Government and director of the Municipal Health Commission, said that from the current situation, the number of patients in Tianjin has dropped significantly after taking measures such as centralized isolation of close contacts, home management in the sealing (management) control area, restrictions on the flow of personnel, and suspension of gathering activities. "On January 18, there were 14 new locally confirmed cases in Tianjin, all of which were isolated and controlled personnel."

According to reports, Tianjin is highly concerned about whether the virus spills into other places, and the list of personnel who have left Tianjin and close contacts and sub-close contacts has been pushed to the relevant provinces for the first time.

Shanghai, Beijing, Shenzhen and other places that have reported local Cases of Aumi Kerong infection have also quickly carried out circulation tracing, investigation and control, raced with Aomi Kerong, and made every effort to cut off the chain of transmission according to the information released at the local epidemic prevention and control press conference.

At the press conference of the joint prevention and control mechanism of the State Council held on January 15, Zhou Min, deputy director of the Emergency Office of the Ministry of Transport, introduced that the transportation department should do a good job in "control" and "communication". Among them, "control" is the scientific and accurate implementation of transportation control to prevent the spillover of the epidemic.

Zhou Min also stressed that the control of epidemic prevention traffic must not be simplified and one-size-fits-all, but should be implemented layer by layer, rather than increasing the number of layers.

In addition, according to current domestic and foreign reports, some asymptomatic infected people will still become the source of infection and may develop into confirmed cases. Isolation observation or treatment of asymptomatic infected people who have been found is also one of the characteristics of precise control in the mainland.

Anti-import Continuously strengthen source control

At present, Omi kerong has become the dominant epidemic strain in the world, spreading in more than 150 countries and regions, and the risk of importing people and things into the mainland is gradually increasing.

To consolidate the hard-won achievements of prevention and control, anti-import is the top priority.

"Strictly control the import of the epidemic and continuously strengthen source control." He Qinghua, a first-level inspector of the Disease Control Bureau of the National Health Commission, listed that the first is to strictly implement the closed-loop management of inbound personnel throughout the process, the second is to strictly control the high-risk post personnel who come into contact with the goods and environment of inbound personnel, the third is to increase the proportion of sampling of relevant inbound items, and the fourth is to strictly implement measures such as terminal disinfection of inbound aircraft.

In addition to the import of external defense, we will not relax, insist on the same defense of people and things, and when racing with Omicron, it is very critical to detect the epidemic in time and early.

At 24:00 on January 8, 2 new local cases in Tianjin were confirmed as Aomi Kerong infection; from 7 o'clock on the 9th, Tianjin launched the first nucleic acid testing for all employees... From 6 o'clock on the 20th, Tianjin launched the fourth nucleic acid test for all employees.

How to ensure that nucleic acid testing "does not leave a household, does not miss a person"? Many places have carried out "knocking on the door" operations to understand and master the nucleic acid testing situation of special areas and groups of people one by one, and to find out the bottom number of the epidemic.

"Continue to carry out monitoring and early warning of key populations, key places and key units; quickly deal with every sporadic or clustered epidemic that occurs, and effectively curb the further spread of the epidemic." He Qinghua said.

Do not be paralyzed Adhere to daily hygiene protection

Experts organized by the National Health and Health Commission to study and judge that the mainland's general strategy of "external defense against imports and internal defense against rebound" and the general policy of "dynamic zero clearance" are still valid for Aomi Kerong.

It is reported that the Chinese Center for Disease Control and Prevention has established a specific nucleic acid detection method for Omilon, and continues to carry out viral genome monitoring for possible imported cases and associated indigenous cases, which is conducive to the timely detection of possible imports or associations with local Omikeron.

He Qinghua believes that the recent partial epidemic in China was discovered after a long period of hidden transmission, which is also related to the high vaccination rate of the mainland population to a certain extent. Some infected people have no symptoms, and some have symptoms late and relatively mild symptoms, so the difficulty of finding them is relatively increased. The mainland should also continue to promote COVID-19 vaccination.

In the face of Omikeron, what are the precautions for the public in their daily life and work?

Experts from the Chinese Center for Disease Control and Prevention organized by the National Health Commission believe that wearing masks is still an effective way to block the spread of the virus, and the same applies to Omi kerong. Even after completing the full vaccination and vaccination of the booster, it is also necessary to wear a mask in indoor public places, public transportation and other places. In addition, wash your hands frequently and ventilate indoors.

At the same time, do a good job of personal health monitoring. When there are suspected symptoms of new crown pneumonia, such as fever, cough, shortness of breath and other symptoms, timely monitor body temperature and take the initiative to seek medical treatment. Reduce non-essential travel, try not to travel to high-risk countries or regions, and if necessary, strengthen personal protection during travel to reduce the risk of infection with Aumechon.
