Diseases suppressed during Covid are back

The Covid-19 epidemic has subsided in most parts of the world, and with it, many social restrictions have been put in place to control its spread because people are eager to return to pre-lock life.

But in its place has emerged a series of viruses that act in new and different ways.

Take seasonal flu, commonly known as fever. The U.S. winter flu seasons of 2020 and 2021 were the mildest reported in both deaths and hospitalizations. More cases were Selected in February And further climbed in the spring and summer as the Govt restrictions were lifted.

Dr Scott Roberts, associate medical director for infection prevention at Yale-New Haven Hospital, told CNBC on Tuesday that “we did not see the flu season in the United States until June.

“The Govt has made a huge impact on it. Now that people have unmasked, places are opening up and we are seeing viruses operating in different ways than ever before,” he said.

And the flu is just beginning.

We see very different behaviors for many viruses in many ways.

Respiratory syncope virus, a common cold-like virus during the winter months, showed an increase last summer, with an increase in cases among children. Europe, USA and Japan. Then, in January of this year, the outbreak of adenovirus 41, which commonly causes gastrointestinal disease, became an obvious cause. Mysterious and severe liver disease Among young children.

Elsewhere, the state of Washington is enjoying its experience of The worst outbreak of tuberculosis In 20 years.

The recent outbreak of the monkey box, a rare viral infection commonly found in central and western Africa, has left health experts confused. More than 1,000 confirmed and suspected cases Forms in 29 homeless countries.

Viruses behave badly

There are at least two genetically distinct monkey box types It is now circulating in the United States, the U.S. Centers for Disease Control and Prevention reported last week that it could develop from two different spillover infections from animals to humans.

The As noted by the World Health Organization As early as last week, the virus with symptoms such as fever and skin lesions may have been undetected in the community for “months or even years”.

A portion of the skin tissue harvested from a wound on a monkey’s skin was infected with the monkey box virus, magnifying 50 times in 1968 on the fourth day of rash development.

“Both strains indicate that this has been going on for a longer time than we first thought. We are at a critical juncture now,” Roberts said. He noted that the coming weeks will tell about the course of the virus The incubation period is 5 to 21 days.

It is unknown at this time what he will do after leaving the post. Most importantly, it seems to be spreading within the community – Most commonly through sex – Resists traveling from commonly found places. There are also symptoms Appear in new ways.

“Patients are different than we’ve been taught before,” Roberts said, adding that some affected patients develop immediate rashes and ulcers, especially in the genitals and anus, avoiding symptoms such as early fever.

“There are a lot of unknown things that make me anxious. We see very different behaviors for many viruses in many different ways,” he said.

Restrictions reduce exposure and immunity

One explanation, of course, is that covet-induced restrictions and mask-wearing over the past two years have provided little opportunity for other infectious diseases to spread in the same way they once did.

Where viruses could have slipped, public health monitoring was often missed because they were often centered on infection.

That was true of Washington’s outbreak of tuberculosis. According to local health officials, parallels between the two diseases allowed TB to go undiagnosed.

During Govt infections, many children do not have access to primary care, including childhood vaccines.

Now that the disease-induced controls have been relaxed and routine habits have resumed, the retreating viruses have found fertile ground for new social and travel-hungry hosts.

The latest monkey outbreak is thought to have originated in at least one area Two mass events in EuropeThe WHO’s leading adviser said last month.

Meanwhile, less than two years of exposure has reduced individual immunity to diseases and made society as a whole more vulnerable. This is especially true for young children – usually germs – who miss the opportunity to acquire antibodies against common viruses, socializing their mother’s uterus or in the early years.

Childhood vaccines were missed

This explains the increase in cases of acute hepatitis of interest among children, according to health experts exploring possible links to Govt controls.

“We are also exploring whether increased exposure due to low exposure during Govt-19 infections may play a role.” The UK Health Care Agency said in April.

Centers for Disease Control and Prevention have expressed concern that the curfew could cause more children. Avoiding childhood vaccines increases the risk of other vaccine-resistant diseases such as measles and pertussis.

“During Govt infections, many children do not have access to primary care, including childhood vaccines,” Jennifer Horny, a professor of epidemiology at the University of Delaware, told CNBC.

“Vaccine campaigns are needed worldwide to prevent the spread of these diseases,” he added.

Beware of tracking pro

There is now greater awareness and monitoring of public health issues following an outbreak, and the detection of certain outbreaks is becoming more common.

“The Govt has raised the profile of public health matters so that we pay more attention when these events occur,” said Horny, adding that the public health systems set up to identify Govt helped diagnose other diseases.

Professor Iyal Leshem, an epidemiologist at the Sheba Medical Center, acknowledged: “The general public and the media are increasingly interested in zoonotic outbreaks and infectious diseases.”

This does not mean the disease is high, but it is more focused.

However, he also warned of the role of “monitoring dependence”, which makes it more likely that individuals and medical professionals will report cases of the disease. It suggests that some viruses, such as the monkey box, may seem to be growing when they were previously less reported.

“It doesn’t mean the disease is high, but it gets more attention,” Leshem said.

However, he noted that increased surveillance of infectious diseases was not a bad thing. With increased spread and mutation of infectious diseases – as seen with Covit-19 – greater awareness and understanding of the dynamics of the disease, the better.

“Public and media focus will enable governments and global organizations to direct greater resources for the monitoring and protection of future epidemics,” Leshem said, highlighting research, monitoring and intervention as three key areas.

“These investments must occur globally to prevent and reduce the next epidemic,” he said.
