BEWARE OF THOSE WHO HAVE OVERCOME COVID! Increased concern about the spread of the new coronavirus

New subvariants of the virus break through all lines of defense, even the immunity of those who have already survived the first omicron strain.

A group of authors with access to America’s largest health care system during the pandemic published numerous studies related to the health consequences of Covid, as well as how reinfection can affect people, reports Substack.com. The number of patients with the new omicron variant BA.4/5 has caused a new wave of hospitalizations in Portugal and South Africa, and the number of patients is growing in many countries in Europe and Australia.

The authors compared people with reinfections and those with just one coronavirus infection and found that there was a doubling of the number of deaths, an increase in the number of people with cardiovascular difficulties, as well as those with harmful lung outcomes, and a threefold increase in risk. of hospitalization.

When it comes to reinfection, the findings are worrying. Earlier reinfections were quite rare, but when the omicron strain appeared, reinfection became much more common. New variants of the omicron strain skillfully evade immunity, and even immunity developed after infection with the BA.1 omicron variant that most people had in early 2022.

New omicron subvariants produce many more recurrent infections. The current omicron BA.4/5 genome has the highest resistance to immunity of any variant since the start of the pandemic.

The risk of re-infection is greatly increased due to the new mutations we are exposed to. Strain BA.2.12.1 mutated in L452k and strain BA.4/5 has two more mutations. Omicron strain BA.1 leaves rather weak and limited immunity that cannot protect us from BA.2.12.1 and BA.4 / 5 subvariants.

Although omicron leaves much less of an impact on human health than delta strains, the number of infected strains of omicron and its subvariants is far greater than any other wave. The absolute risk of developing a state of prolonged covid is still real even with the omicron variant of the coronavirus, scientists believe and express concern about the way these omicron subvariants bypass the immune system.

Hence the fear of scientists that the booster dose of the vaccine may not achieve broad-spectrum protection as previously expected, because it was not assumed that our immunity would have such a hard time recognizing the new omicron variant.

Although there are no clear warnings for now, it is easy to prepare again for wearing masks, social distancing, regular ventilation of rooms and all measures related to preventing the spread of infection.
