The world may be looking at an unfortunate new normal for how viruses spread.
Doctors and medical experts are seeing a strange resurgence of diseases that were essentially on hold during the violent spread of COVID — and the general population, especially children, susceptible to naturally acquired immunodeficiency from isolation in the past few years, Stat News reported.
Medical experts are looking into the possibility that babies born with a pandemic have fewer antibodies — particularly for respiratory diseases — passed on to them from their mothers, according to Hubert Nesters, professor of virology and molecular diagnostics at University Medical Center, in Groningen, the Netherlands. .
Even those born before COVID, who experienced dramatic isolation by not attending school or daycare in person, are showing remarkable changes.
While looking for antibodies in young children, a “honeymoon infection” was found in blood tests, said Marion Koopmans, another Dutch medical scientist.
You really see that children in the second year of the epidemic have much lower antibodies to a group of common respiratory viruses. “They are becoming less vulnerable,” said Koopmans, head of the department of virology at Erasmus Medical Center in Rotterdam.
Scientists are looking into a causal relationship with children who have fewer antibodies and the recent high number of hepatitis in children. It is likely caused by type 41 adenovirus, an illness that can cause flu-like symptoms in patients. They are weighing the possibility that this tape is highly contagious as a result of weak immunity.
“There’s some suspicion that this might happen with cases of hepatitis,” said Kevin Mesakar, MD, a pediatric infectious disease specialist at Children’s Hospital of Colorado.
“I think sometimes to connect the rare complication points of common diseases, you just need enough cases to start putting the pieces together,” he added.
Public health workers also fear outbreaks of disease caused by the interruption of vaccines because many children lost their routine vaccinations during the pandemic, according to Thomas Clarke, deputy director of the division of viral diseases at the Centers for Disease Control and Prevention.
“We are very focused on children who have not been adequately vaccinated with their routine childhood vaccinations because it is the setting for the introduction of measles. But then there were also a lot of children who did not have the usual kind of virus that they might have been exposed to.”
Since many children did not catch bedbugs and diseases that they would have been exposed to at a young age, they may develop more serious conditions as they age, according to Clark.
“Whether we’ll see this kind of thing in a short period of time I think is a big question mark,” Koopmans said. “But I think it’s definitely something worth watching closely.”
I’ve also noticed that after a year or two low in flu transmission, there can be a marked decrease in those with combative antibodies that would protect themselves.
And she warned that we may see a “larger and more sensitive group in adults”.
In addition to weakened immunity, the easing of COVID restrictions could have also contributed to the spread of diseases, for example, Monkeypox – an autoimmune virus found mostly in Central and West Africa – which has become a cause for concern in Europe and other countries. we.
“If you look at what has been happening in the world over the past few years, and if you look at what is happening now, you can easily wonder if this virus came into the UK two to three years ago, was moving from under the radar screen, [with] Slow transmission chains,” David Heyman, who chairs the WHO’s Health Emergencies Program Advisory Committee, told Stat News.
“Then all of a sudden it all opened up and people started traveling and mixing.”
However, other scientists, such as England’s Peter Broden, Professor of Pediatric Immunology at Imperial College London, are quick to allay great concern about these biological variables.
“I think we can expect some of the presentations to be out of the ordinary…not necessarily really intense. I mean, it’s not a doomsday projection. But I’m thinking a little bit out of the ordinary.”
“I think once a number of people are infected, herd immunity kicks in and the virus goes away,” Brodin said of viruses in general. “We haven’t fundamentally changed the rules for infectious diseases.”
