Britain is currently facing its own the fifth wave with Corona virus infection covid-19 infections, experts warned, as the number of cases reached 1.7 million in the latest weekly figures, a 23 percent increase in the week (wow).

Even more alarmingly, hospitalizations increased by 31 percent wow, rising more than in the past Omicron revival back in March.

The situation first became apparent after a four-day public holiday to celebrate the Queen’s Platinum Jubilee, when 43 per spike Art coronavirus cases have been reported and there are fears that other major summer gatherings such as Glastonbury, Notting Hill Carnival and the Edinburgh Festival could become super-spread events if proper precautions are not taken.

It is reported that the surge is due Omicron BA.4 and BA.5 subvariantsstrain that spread rapidly across the UK in December 2021 and January 2022 before gradually disappearing.

These latest incarnations were first discovered in South Africa in January and February respectively and are actually Omicron’s grandchildren.

They have three mutations in their spike proteins, which are feared to allow them to relearn to attack human lung cells.

This means they have more in common with the earlier, more dangerous versions of Alpha and Delta than with the highly transmissive but milder Omicron, which targeted upper respiratory tissue.

Potentially, these mutations could also allow subvariants to bypass antibodies from past infections or vaccinations and thus overcome immunity.

Preliminary evidence from Professor Kei Sato of the University of Tokyo in Japan appears to point to this, prompting the virologist to comment: “Overall, our studies show that the risk [these] The Omicron variants, particularly BA.4 and BA.5, are potentially greater for global health than the original BA.2.”

For now Immunity in Britain is high87.1 percent of the population received two doses of the vaccine and 68.6 percent of people were revaccinated, the public largely acted as if there had never been a pandemic since the last Boris JohnsonThe US government’s unpopular restrictions were lifted a month ahead of schedule on February 24, ditching masks and distancing and returning to normal life.

However, it has been more than six months since the last major booster vaccination was given in the run-up to Christmas and New Year, and immunity may be starting to wane, potentially leading to more patients requiring professional care and possibly even dying now or later in the year when flu season hits.

Professor Adam Finn, a member of the government’s Joint Committee on Immunization and Vaccination, has already called for a new round of boosters will be available until September.

“Booster protection does wear off, especially from a milder infection, and after a while from a severe infection. So it’s disappointing for all of us in terms of these vaccines, which have otherwise been very valuable in terms of the pandemic,” he told BBC Radio 4’s. today program.

“But we will need to provide boosters, especially to people who are at risk of becoming very seriously ill if they get it later this year.”

The World Health Organization (WHO) has been monitoring these strains since April, and currently Omicron, including its subvariants BA.1, BA.2, BA.3, BA.4, BA.5 and progeny lines, is the only form of Covid that he recognizes as a “Care option”.

Fortunately, variants previously in this category such as Alpha (formerly known as B.1.1.7 and first discovered in Kent), Beta (formerly B.1.351, from South Africa), Delta (B.1.617.2 , India) and Gama (P.1, Brazil) have been delisted and are not currently believed to be threatened.

Other variants once studied, such as the Epsilon, Eta, Iota, Kappa, Lambda, Mu, Theta, and Zeta variants, are no longer even on the WHO’s “interesting variants” list.

The European Center for Disease Prevention and Control the same way lists the same Omicron subvariants of concern, with the exception of strain BA.3, which has been moved to monitoring status only.

In the US, the Centers for Disease Control and Prevention (Center for Disease Control) currently lists only the same subvariants as “of concern” but keeps Alpha, Beta, Delta, Epsilon, Eta, Gamma, Iota, Kappa, Mu, and Zeta listed as “Options tracked”.
