Mace's early reading 丨Omi Kerong "sister strain" BA.2 doubled in contagiousness and may soon become mainstream

1. The "sister strain" BA.2 of the Aumecreon "sister strain" has doubled in contagiousness in nearly half of the states in the United States

According to the US Consumer News and Business Channel (CNBC), as of the 28th local time, nearly half of the states in the United States have found subtype of the variant strain BA.2 infection of the new coronavirus Omilton strain, and at least 127 cases of BA.2 strain infection have been found in the United States.

According to data from the Danish National Institute of Serum Research, the BA.2 subtype is 1.5 times more contagious than the mainstream Omiljung strain "BA.1". Troels Lillebaek, chairman of the Scandinavian National Committee, said the BA.2 subtype replaced Omikeron as the mainstream strain in Denmark within a few weeks.

The British Health Security Agency also said on the 28th that the BA.2 subtype strain has a "significant" growth advantage compared with the original Aomikron strain. An analysis of infection cases in England found that the "Sisters of Omikejong" BA.2 spread faster than the original Omiljun strain.

The World Health Organization has not labeled the BA.2 subtype strain as a "worrisome variant virus." But WHO officials have repeatedly warned that new variants of the virus will emerge as the Omiljun strain spreads worldwide at an unprecedented rate.

2, Danish scientists: the transmissibility of the Aumi kerong subtype strain BA.2 may be 1.5 times that of the original strain

Data from statens Serum Institut, which monitors infectious diseases in Denmark, suggest that the subtype "BA.2" of Omiqueron may be 1.5 times more transmissible than the original Omiljung strain "BA.1". However, there is no evidence that BA.2 is more toxic, nor is there any evidence that BA.2 is more able to break through the immune effect of vaccines than BA.1.

3. Although Aumechon has hospitalized more children, it does not mean that it is a greater threat to young children

Due to the huge amount of mutations and high contagiousness of the Omicron has attracted widespread attention, the number of infections caused by the RecentLytes of American children due to the continuous increase in the number of infections caused by the Aomi Kerong has made people more worried about the impact of this variant on children. Studies have shown that while more children are exposed to and infected with it because of the much more contagious nature of the previous variant, the increase in pediatric hospitalizations does not mean that the variant will be a greater threat to young children.

Early surveillance data from South Africa show that during the peak of Infection in Omikejong, children and adolescents under the age of 20 accounted for 17 per cent of all hospitalizations, and children under 5 accounted for 10 per cent of all hospitalizations. Since Entering the U.S., hospitalization rates for every 100,000 children aged 4 or under have increased by nearly 50 percent since The Economist reported, and hospitalization rates for unvaccinated children ages 5 to 11 have increased by 70 percent.

The continued increase in hospitalization suggests that the impact of Omikejong on children may not be as small as on adults, but the increase in paediatric hospitalization rates is more due to the more contagious variant virus Omiljung, as this increase reflects an increase in infectivity in all age groups, so the claim that Omikeron makes it easier for children to be hospitalized is not valid.

However, the scientists found that for those who have not been vaccinated, especially those under the age of five, their likelihood of infection increases significantly, which shows that it is necessary to start childhood vaccination as early as possible.

4. Merck: 6 laboratory studies have shown that oral anti-COVID-19 drugs are effective against Omi kerong

Merck and its partner Ridgeback Biotherapeutics today announced that six laboratory studies have shown that its experimental oral anti-coronavirus drug molnupiravir is effective against the rapidly spreading Omiljung variant, according to Sky News.

These data assessed the antiviral activity of mornupiravir and other antiviral drugs against the strains of the novel coronavirus variant of concern. However, the two companies said that Molnupiravir's human trials against Omikeron had not yet been conducted.

5. Taiwan's "Six Capitals" have all fallen! More than 90% of the 407 people in Taiwan have been infected with Omicron

According to the official website of the "Disease Control Administration" of the Taiwan authorities, the "Geographical Distribution Map of Local Cases" shows that since January 28, there have been 407 cases of locality, and yesterday 2 new people in Taichung City were infected, and the map lights changed color overnight, from off-white to light earth yellow, so far, the "six capitals" on the island have all fallen.

According to statistics, this year has accumulated 407 cases of locality, 10 counties and cities fell, of which Taoyuan City accounted for the most, followed by Kaohsiung City with 75 people, Taipei City with 21 people, New Taipei City with 16 people, Hsinchu City with 6 people, Hsinchu County with 5 people, Yilan County with 5 people, Tainan City with 4 people, Taichung City with 2 people and Keelung City with 1 person.
