The UK recorded more than 600 Omicron infections, the largest one-day increase since the emergence of the new strain, prompting experts to call for restrictions.
The British Health and Security Agency said on December 11 that there were 633 new confirmed cases in the country Omi Kron, Bringing the total number of new mutation infections in the country to 1,898. According to the agency, no cases of Omicron infection have resulted in hospitalization or death.
The model released by scientists from the London School of Hygiene and Tropical Medicine (LSHTM) on the same day shows that Omicron is likely to cause a wave of large-scale infections in January 2022, and may cause 25,000-75,000 deaths in the next UK if no additional measures are taken To prevent the spread of the virus, it takes 5 months.
“We know very well that vaccines are important, and booster injections are the best line of defense against this virus. That’s why we urge people to get vaccinated as soon as possible if they meet the conditions,” the expert said. LSHTM said. “We encourage people to abide by the regulations, wear masks, work from home as much as possible, check regularly and give booster injections when they receive a call.”
The most pessimistic scenario is that by the end of April 2022, 500,000 people will be hospitalized due to the virus, and the number of hospitalizations per day may be twice the peak in January. The number of infections will depend on the effectiveness of the strain evading the vaccine and the effectiveness of the booster injection, but the data is not yet clear.
The South African scientist who reported Omicron to WHO for the first time said that the symptoms caused by Omicron were not as severe as Delta, but it was too early to emphasize this conclusion.
Rosanna Barnard, an expert at the Element Mathematical Modeling Center, said: “In our most optimistic scenario, the impact of Omicron in early 2022 will be mitigated by mild control measures, such as working from home.” LSHTM’s infectious disease said. “However, the most pessimistic scenario suggests that we may be subject to stricter restrictions to ensure that health services are not overwhelmed.”
The government of British Prime Minister Boris Johnson is not considering stricter measures, but the goal is to vaccinate all 18-year-olds by the end of January.
According to data from the UK Health and Safety Agency, both AstraZeneca and Pfizer vaccines appear to be less effective in preventing symptomatic infections in people exposed to Omicron, although preliminary data indicate that the effectiveness after the third injection seems to increase to 70%-75 %.
