Several countries in the world are witnessing a rise in the number of infections with the Corona virus, so what will happen to Corona during the summer?

Will we be facing an unprecedented COVID-19 summer?

Could the increase in numbers lead to a tightening of procedures again?

A Russian expert reveals what will happen to Corona during the summer

A biophysicist, Dr. Nelly Sosedova, announced that a new strain of the emerging corona virus (Covid-19) will spread in China or an eastern country this summer, according to what was reported by "Russia Today".

The specialist indicated, in an interview with Radio "Sputnik", that the spread of Corona infection continues in China, and thus will lead to the emergence of a new variable.

"I think that during this summer a new mutation will appear in Corona, and this is inevitable. Because in an eastern country like China, where Covid-19 is actively spreading, a new strain will appear," she says.

According to Sosedova, the Corona virus usually travels from east to west.

Therefore, "the new mutation will appear in an eastern country and move to Russia next fall, which may lead to an increase in Covid-19 infections."

"It will arrive in Russia between next September and October, coinciding with other respiratory infections. Therefore, we expect an increase in Covid-19 infections" in Russia next fall, she says.

She adds that, of course, the spread of previous variants of the Corona virus has decreased significantly as a result of vaccination campaigns and the recovery of many from the disease, meaning that there is a collective immunity that has arisen.

But this immunity is not against new mutations, so no one knows what the new mutation will be like.

Will we be facing an unprecedented COVID-19 summer?

The answer is not clear, but the previous data do not indicate that the Corona virus disappears or recedes during the summer.

There are also real fears of the emergence of new strains.

Omicron sub-strains evolve to target the lungs and overcome immunity

A report in the British newspaper "The Independent" said that the "Omicron" subspecies is evolving to target the lungs and overcome immunity.

With the increase in cases in the UK, scientists fear that the sub-variables may be similar to the more deadly alpha and delta variants.

The latest omicron sub-variants may have evolved to target the lung, raising concerns that the next wave of COVID-19 may begin.

Recent data from the British National Health Service (NHS) showed that hospital admissions for Covid-19 patients in England started to grow again.

The World Health Organization has been investigating two omicron sub-variables since last April to assess whether they are more contagious or more dangerous than the previous one.

Both BA.4 and BA.5 have been added to the organization's watch list.

Covid-19 cases are on the rise in the UK

The new figures last week showed that Covid-19 infections in the UK increased by 43%, and the two new sub-variables are believed to be behind the sudden increase.

In addition, about 1.4 million people in the UK contracted coronavirus in the week ending June 11, up from about 990,000 the previous week.

According to preliminary data from University of Tokyo researcher Kai Sato and colleagues reported by The Independent, strains of BA4, BA5 and BA21 (21 BA.2.12.1) may have evolved to refeed the infection of lung cells. , rather than upper respiratory tissue, making it more similar to previous variants, such as alpha or delta.

The tendency of Omicron strains to prefer infection of non-pulmonary tissues may be one reason why infections tend to be milder in most people.

"Altogether, our investigations indicate that the risks to global health of the Omicron variants, particularly PA4 and PA5, may be greater than the risks to the original PA2," Sato said.

Professor Sato's experiments indicate that PA4, PA5 and PA21 multiply more efficiently in human lung cells compared to PA2, while additional experiments on mice indicate that B A4 and PA5 may cause more serious illness.

Even in the summer Corona is not over

Dr Mary Ramsay, from the UK's Health Security Agency, said: "As summer approaches, it is still important to remember that COVID-19 has not gone away, and that vaccination is done to reduce the risk of serious illness with the virus."

An increase in Corona injuries

Several European countries are seeing a spike in new COVID-19 infections, with experts warning that with nearly all restrictions lifted and often reduced, cases could rise throughout the summer leading to more deaths, according to a report in the Guardian newspaper. (the guardian).

In France, for example, Dr. Benjamin Davido, an infectious disease specialist at Raymond Poincaré Hospital, said, "The epidemic is accelerating again, despite the hot weather."

"The new sub-variants of PA4 and PA5 are more contagious by 10% to 15%, and this gives the virus an extra boost," Davido told French radio, adding that the situation in the medium term may become "very severe." And difficult "in the country's hospitals."

The health expert, Dr. Damien Maskrett, told France 2 television that the "PA4" and "PA5" variants led to a significant excess mortality in Portugal, adding that hospital admissions in France rose by 27%, and admissions to intensive care increased by 17. % In a week.

Will the increase in Corona injuries lead to the tightening of procedures again?

This depends on the country, vaccination rates, and the ability of its health system to absorb the many cases.

But from a theoretical point of view, if an explosion in Corona injuries threatens to collapse the health system in a particular country, officials in it may be forced to re-impose Corona measures that were previously applied.
