(Fighting against New Coronary Pneumonia) Beijing re-infected people while facing Omicron and Delta challenges
China News Agency, Beijing, January 18 (Reporter Du Yan) Since the current round of the epidemic in January this year, as of 15:00 on January 18, Beijing has reported a total of 3 local confirmed cases of new coronary pneumonia and 1 positive nucleic acid test.
When Beijing conducted nucleic acid testing on infected people, it detected the specific mutation sites of the Omicron variant and the delta variant.
According to a report from the Beijing Center for Disease Control and Prevention, Beijing added 1 local confirmed case on the 15th.
After re-examination and re-collection by the two-level CDC laboratories in Beijing, the nucleic acid test results were all positive, and the specific mutation position of the Omicron variant was detected.
From 0:00 on January 17 to 15:00 on January 18, Beijing added 2 new confirmed cases of local new coronary pneumonia and 1 positive nucleic acid test.
At a press conference held on the 18th, Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention, said that the two new confirmed cases were the mother who reported the confirmed case on January 15, and a colleague on the same floor of the unit.
She said that the new case of a positive nucleic acid test was a worker who came to Beijing in November 2021, and the specific mutation site of the delta variant was detected in the nucleic acid test.
Pang Xinghuo said that at present, epidemiological investigations have been carried out on the above-mentioned people, their close contacts have been traced, risk-related points have been checked, and various risk personnel have been classified and controlled.
At present, China is facing the dual challenge of imported delta and Omicron mutant strains.
So, what are the similarities and differences between the Omicron variant and the Delta variant?
Li Ang, a spokesman for the Beijing Municipal Health Commission, introduced at a press conference on the 17th that Beijing Ditan Hospital, which treats confirmed cases, provides clinical symptoms, admission virus testing, and chest imaging of patients with confirmed Omicron variant of new coronary pneumonia. The inspection situation is closely monitored and analyzed. From the current observation and monitoring, the clinical symptoms of the delta variant patients and the Omicron variant patients are generally similar, and the clinical symptoms of the Omicron variant patients are mild, and the chest imaging manifestations are mild. , but more contagious.
How to prevent Omicron mutant infection?
How effective are existing vaccines for prevention?
At the press conference held on the 18th, Li Ang pointed out that the World Health Organization emphasized that vaccination is still the safest, most economical and most effective prevention and control measure for epidemic prevention and control.
People with low Covid-19 vaccination rates are at higher risk of contracting Covid-19 and developing severe illness.
According to data released by the World Health Organization, 90% of patients with severe new crown cases in the world have not been vaccinated against the new crown.
Li Ang said that the existing research results show that the Omicron variant has not completely escaped the immunity of the existing vaccine, and the existing vaccine still has a certain protective effect on the Omicron variant.
For the Omicron variant, existing vaccines are still effective in preventing severe illness and death.
He believes that in the face of the epidemic of Omicron mutants with enhanced immune escape ability, it is necessary to accelerate the promotion of new crown vaccination to strengthen immunization, increase the vaccination rate of people over 60 years old, and steadily carry out vaccination for people aged 3 to 11 years, and further strengthen the capital. immune barrier.
As of 24:00 on January 17, a total of 58.041 million doses of Beijing's new crown vaccine have been vaccinated, 22.566 million people have been vaccinated, 21.897 million people have been vaccinated in the whole process, and 13.684 million people have been boosted immunization.
Among them, a total of 8.266 million doses and 3.13 million people were vaccinated for people aged 60 and over; a total of 2.847 million doses were vaccinated for people aged 3 to 11, and 1.505 million people were vaccinated.
In the face of the simultaneous attack of Omicron and Delta, has the policy of entering and returning to Beijing been adjusted?
At the press conference held on the 18th, Xu Hejian, spokesman of the Beijing Municipal Government, reiterated that in order to further detect and control the risk of the epidemic earlier, one must hold a negative nucleic acid test certificate and a "Beijing Health Treasure" green code within 48 hours before entering or returning to Beijing. Based on the policy of returning to Beijing, from 0:00 on January 22, 2022 to the end of March, people entering and returning to Beijing must undergo a nucleic acid test within 72 hours after arriving in Beijing.
However, he said that those who leave Beijing within 72 hours after arriving in Beijing do not need to undergo nucleic acid testing.
Infants and children under the age of 3 do not need to undergo nucleic acid testing within 72 hours after arriving in Beijing.
Xu Hejian emphasized that commuters in the Beijing area continue to implement the existing policies and regulations, that is, the first entry and return to Beijing must hold a negative nucleic acid test certificate within 48 hours, and each time after entering or returning to Beijing, a negative nucleic acid test certificate within 14 days is sufficient.
However, in view of the current epidemic situation, commuters from Tianjin must hold a negative nucleic acid test certificate within 48 hours each time they enter or return to Beijing, and the policy will be adjusted in time after the epidemic has stabilized.
