Coronavirus has also changed the usual viruses!  Worrying developments in hospitals ...

Have you had a cold more often than before? You are not alone. Following the coronavirus pandemic, the viruses we are used to began to behave unusually. This has led to surprisingly serious infections for individuals.

Last month, 7 different out-of-season respiratory viruses were observed in children who were taken to Yale New Haven Children’s Hospital after they became ill in the United States. These viruses included Coronavirus, Adenovirus, Rhinovirus, influenza, parainfluenza, and respiratory syncytial virus (RSV).

Thomas Murray, a hospital infection control specialist and associate professor of pediatrics, said some of the children admitted to the hospital were infected with 2 viruses and some 3 viruses at the same time.

Murray pointed out that it is not normal for viruses to appear so often that “It’s not typical of any time of year, especially not for May and June at all.” used expressions.


Researchers say Yamagata may have become extinct or lurking in our immune system.

The respiratory syncytial virus, known as RSV, is most common in the winter months. Rhinovirus, the cause of the common cold, is usually mild and rarely sends people to hospital. The flu, which did not appear last year and was briefly recalled, disappeared again in January with the expansion of the coronavirus variant of Omicron. Influenza has not been present since 2020 ‘Yamagata’ He returned to us without his line.

More than two years after the coronavirus pandemic, known viruses have recently behaved in an unusual way.

IS IT RESPONSIBLE FOR PANDEMIC RULES?class = “medianet-inline-adv”>

Unusual virus movements have already begun to be felt strongly in hospitals. While experts keep the idea of ​​antiviral vaccines available in the spring and even in the summer, researchers are investigating whether pandemic rules such as coronavirus restrictions, masks and social distance are effective in this situation.

Epidemiologist Michael Mina, CEO of eMed Digital Health Platform, “big natural experiment” He noted that the emergency measures taken during the pandemic had upset the balance;

“The measures we have taken to avoid coronavirus infection have actually affected the transmission of other viruses we are used to. If you are not exposed to viruses that the body has known for a long time, you may not be able to protect yourself when this leads to off-season fluctuations. in populations and infections that are surprisingly fatal to individuals. “


With the advent of the summer months and the impact of an intensive vaccination campaign around the world, many countries have lifted the strict restrictions they have adopted. People took off their masks and made close contact inside. At this point, viruses that had not been circulating for a long time began to move out of season, although other conditions were not appropriate.

Unusual conditions, such as the frequent occurrence of shingles in adults aged 35 to 40 years and smallpox, which recur especially in the elderly, are all related to immune memory and unusual virus movements.

Richard Martinello, a respiratory specialist at the Yale School of Medicine, said that even the common cold is now more severe and stubborn than before. “Even our cold patients look worse than before. When we have regular contact with viruses, our immune system responds and recovers without being too sick. Now that has changed.” he said.

Epidemiologist Mina pointed out that the immune system has its own memory system and explained that the natural balance is disturbed when people stop being exposed to viruses on a regular basis.


Researchers are now investigating the effects of the post-pandemic period on our immune system and the unusual spread of viruses.

The researchers say we need a little more time to understand the new balance after coronavirus.
