Infringement psychological warfare is frequent due to the central government's authority under the Infection Prevention Act, which is chaired by the Prime Minister according to the Disaster Act, and the heavy water version of the Ministry of Health and Welfare.
While the quarantine authorities could not approach the antibody formation rate against herd immunity, the central government unilaterally announced the 'achievement of herd immunity' to the public media, and the Korea Centers for Disease Control and Prevention (KCDC) will prepare future corona prevention measures based on the results of the first scientific and private researcher figures. policy was announced.
Professor Shim Eun-ha (Department of Mathematics, Soongsil University) said that the national antibody formation rate is 75%, combining natural immunity caused by infection and artificial immunity through vaccination, in 30% of the total population and 64% of those who received the third dose of vaccine with a history of corona infection. To do this, the antibody formation rate must exceed 90%.”
Sohn Young-rae, head of social strategy division (Ministry of Health and Welfare), appeared on TBS' 'Kim Eo-jun's News Factory' on the same day and said, "We judge that considerable collective immunity has been achieved through vaccine immunity such as the third vaccination and natural immunity due to Omicron infection." If it is stabilized well, I think the risk of it spreading into a big epidemic again is significantly lowered," the government's diagnosis result was announced.
In a personal broadcast rather than a briefing, Director Sohn said, "Yes," and said "yes" to a question about changing the quarantine policy when asked, 'In June or July, the medical system will be switched and the outdoor mask duty will be lifted.'
Professor Shim said, "It is concluded that it would be difficult to completely remove social distancing or not use a mask, but it was analyzed that it would be possible to live without a mask outdoors around summer. It was predicted that the possibility of new mutations would be high after the summer, when the effect of tea inoculation began to decline,” he told Yonhap News TV.
Director Sohn told 'Kim Eo-jun', "In order to live with Omicron and go back to daily life, the medical system itself must completely transition to the daily medical system." We are working on overall post-Omicron countermeasures, including the
The new XL mutation is a recombination of Omicron mutation and Stealth Omicron mutation, and it was first discovered in the UK in February and confirmed in Korea on the same day. “The change in characteristics is not expected to be significant, and the impact is expected to be limited,” he said.
The WHO said, "XE has a virus growth rate of about 10% higher than that of BA.2, and the transmission power of XL has not yet been confirmed." "We added two mutations named BA.4 and BA.5 to the monitoring list. We have started tracking these mutations that require further research on immune evasion,” he said on the 11th.
Park Young-joon, head of the epidemiological investigation team at the Korea Centers for Disease Control and Prevention (KCDC), said at a briefing on the same day, "The number of primary infections has increased significantly since the Omicron pandemic in February. “I think it is necessary to prepare and evaluate it,” he said.
Regarding the rapid increase in reinfection, the report analyzed that the current domestic reinfection rate of 0.28% is lower than that of the UK, but it is because the number of primary infections has been small. As a result of a re-investigation of all 9,243,907 confirmed cases from January 2020 to March 19, 2022, 0.284% of the total confirmed cases were 26,239 domestic reinfections, and 26,202 people infected twice from reinfection. The reinfection rate was 37 out of the 2nd infection before the Omicron outbreak, 570 out of 579,724 total infected people (0.098%) until December 2021, but the 8,664,146 people infected after the Omicron epidemic surged. Reinfection is 25,632 (0.296%), a threefold increase.
In response to a question about whether the number of people or time restrictions can be removed in 'Kim Eo-Jun', Director Young-Rae Son said, "We are also considering such a plan together." He said, "I am implementing a gradual transition to the daily medical system, and general posts such as the issue of adjusting the class of infectious diseases of Corona 19. We are working on measures for Omicron,” he said on the same day.
As of 00:00 on the same day, the major report announced that there were 21,755 new cases, 1005 cases in critical condition, and 171 deaths.
The determination of infectious disease classification is the sole authority of the head of the Korea Centers for Disease Control and Prevention, and the Minister of Health and Welfare is subject to consultation, and the Prime Minister has no authority.
The Prime Minister and the Ministry of Health and Welfare have shown continuous interest in bio-industry stocks by reinforcing policies on both the infection law and economic growth through the disaster management law through the major and heavy-duty versions. See March 17, 2022>
