More contagious strains of “omicron” BA.5 and BA.5 began their march across Europe and the USA back in June. Without such explosive numbers as in January-February, when Omicron infected hundreds of thousands, but still, WHO experts noted increase in incidence by 30 percent.

Now new strains came to Russia – from mid-July, a slow rise began. And from July 26 every day adds two thousand new cases. Moreover, their danger is that they deftly bypass any immune protection – both from vaccines and from previous diseases. That is, not only those who were ill with “alpha” or “delta” at the beginning of the pandemic, but also those who were ill with the first strains of “omicron” at the beginning of this year, can get sick. So, a new wave is inevitable.

THE MORE WE CONTINUE, THE WORSE WE GET

Caused a big uproar study American scientists who compared the medical data of three groups: those who had been ill once, at least twice and did not get sick at all. Re-infection outcomes were assessed SARS-CoV-2: and each re-infection increases the risk of hospitalization, death and long-term complications. As the doctors found out, covid also has its own cumulative (accumulative) effect – the more infections, the greater the risks. For example, those who were re-infected were twice as likely to die (from all causes) and three times as likely to be hospitalized. And all the consequences (pulmonary, gastrointestinal, cardiovascular, renal, neurological, psychiatric, clotting disorders) all increased significantly after reinfection.

At the same time, according to many American virologists, the consequences of re-infection are still unclear. It is unlikely that each subsequent infection is worse than the previous one. “In fact, this study only showed that re-infection is worse than no re-infection,” said ATLANTIC DAILY virologist Katherine J. Wu.

Did not confirm the opinion that a repeated illness gives a more severe post-COVID and our expert, general practitioner, cardiologist, Ph.D. Vladimir Beketov:

– According to well-known registries and published publications, there is no unambiguous linear relationship between the “number of cases of COVID-19 and the severity of post-COVID conditions”. At the same time, given the complex mechanism of vascular changes after covid, repeated inflammations (i.e., re-infection) can lead to a deterioration in cognitive functions. But directly interpreting this as a post-Covid is incorrect. After all, the post-COVID state – anxiety, rash, diarrhea, vegetative fatigue – is one thing. But vascular dementia, cognitive decline, changes in neurological status associated specifically with vascular damage due to inflammatory processes during illness, especially in elderly patients, are completely different. It is impossible to interpret such changes as post-covid syndrome, despite the fact that they are directly related to the transferred covid. And unlike the post-covid syndrome, such conditions can indeed worsen with repeated infection. After all, any severe inflammation will lead to a deterioration in the permeability of the vascular wall in the central nervous system, nutrition of neuroglia, glial tissue (auxiliary cells of the nervous tissue – approx. Ed.). And potentially leads to cognitive impairment. Such conditions require further studies and selection of special therapy.

HAIR SHEETS IN POSTCOVID

UK scientists listed 62 new symptoms of post-Covid. Having collected data from half a million hospitalized and one and a half million people who were ill at home, scientists, in addition to the already known fatigue, memory problems, loss of smell, shortness of breath, called many more symptoms that were associated specifically with covid.

Among them, decreased libido, difficulty with ejaculation, hair loss, sneezing, and frequent swelling. Most often, women experienced problems. As well as overweight people.

“PEOPLE SHOULD NOT BE SURPRISED IF THEY GET INFECTED”

In America, the omicron BA.4 and BA.5 variants have been raging for a couple of months now. They infect everyone: both those who have not yet been ill (yes, there are some), and those who have recently been ill. “People shouldn’t be surprised if they get infected, and they shouldn’t be surprised if it’s rather unpleasant,” conveys the words Stephen Goldstein, virologist at the University of Utah ATLANTIC DAILY.

True, American doctors and scientists interviewed by the newspaper do not call the new version an apocalyptic threat. While BA.5 currently accounts for about 54 percent of all COVID cases in the US, BA.4 accounts for another 17 percent. The number of hospitalizations rose to its highest level since March.

– Yes, I heard about many people who got sick in February-March, and now they get sick again, – said Ann Hahn, virologist and immunologist at Yale University. – When people are vaccinated or infected, they develop antibodies that can neutralize the coronavirus by sticking to its spike proteins, the spikes on its surface that the pathogen uses to recognize and infect our cells. But BA.4 and BA.5 have several mutations that change the shape of their spines. And they, like swords that no longer fit in sheaths, are now unrecognizable to many of the antibodies that would have disarmed older variants. This is why antibodies in triple-vaccinated people, or people who had early infections, are now three to four times less effective at neutralizing BA.4 or BA.5 than the first Omicron strains.

At the same time, American doctors reassure: you can’t endlessly become infected with “omicron”: yes, its strains differ from their predecessors, but not from themselves. Yes, it is possible for someone to become infected with the new variant despite having recently had covid, but it is still unlikely that they will become infected with it again in the near future.

In addition, despite the fact that BA.5 bypasses immunity, but far from everyone: “We see that new infections are disproportionately common among people who were not previously infected,” said Megan Cull, epidemiologist at the UK Health Security Agency. – In the new wave, those who have not had covid at all before are most infected. And although their share among the entire population is about 15 percent, they make up half of the cases in the new wave. That is, in general, the population still has some protection against infection, even BA.5.

It turns out that covid and immunity have an endless arms race. Until the virus wins. Unfortunately, it is not yet known how our body will react to the delayed consequences, post-COVID after the “omicron” and all its many mutations. Although WHO notes: “Each wave of the virus leaves more people with a long-term or post-COVID state.”

So, as recommended by both Rospotrebnadzor and WHO, we must take care of our health ourselves: do not forget about antiseptics, wear masks in especially crowded public places. Take care of your body as much as possible: walk more, go to bed on time, eat more vegetables and fruits. And get revaccinated. After all, as the experience of countries where the latest versions of the “omicron” are already rampant with might and main shows, any protection is better than none.

MEANWHILE

The brain after covid ages by 10 years

– Studies show that in some post-COVID patients, the loss of gray matter of the cerebral cortex after exposure to SARS-CoV-2 is equivalent to 10 years of aging. And, unfortunately, this happens regardless of the severity of the disease, age and gender, writes the doctor, health organizer, leading expert of the National Medical Association for the development of expert activities in the field of laboratory diagnostics “MedLabExpert” Alexander Solovyov. – In fact, the impact of covid is akin to an injury or even a microstroke. And in such cases, various options for brain games are used. Such games make the brain work and give pleasure (board games, crossword puzzles, quizzes, etc.).

What else:

1. Collect big puzzles.

The brain engages a visual processing system—scanning small pieces, switching from a small puzzle to the big picture, constructing a whole picture. Plus fine motor skills.

2. Memorize and sing new songs.

Better yet, start learning some musical instrument.

3. Play with a sujok ball.

Rolling a prickly ball (sujok) in the palms, exercises with it (even simple ones) stimulate brain activity well.

5. Start Crocheting or Knitting

A very good way to train fine motor skills, unmistakable actions, vigilance and attention.

5. Walk on uneven surfaces

It improves the vestibular system, develops balance and balance control. And it is best to walk barefoot.
