COVID has caused other viruses to behave strangely, experts say, and children are at risk.
Coronavirus has been the world’s top concern for two years, with all the resources spent to control it.
But its existence has influenced the trends and behavior of other bugs, experts say.
It includes hepatitis in children, monkeypox, respiratory diseases and scarlet fever.
Some mainly affected children, and parents were urged to be aware of symptoms and to monitor their children’s vaccination status.
Dr Scott Roberts, a medical expert at Yale, told The Independent: “Now that people have exposed themselves, places are opening up and we are seeing viruses behaving in very strange ways that they did not previously behave.
“We have never seen a flu season extend into June in the US. Clearly Covid has had a very big impact on that.”
Because we’ve spent so much time indoors, immunity to common viruses has dropped.
Normally, kindergarten and school children would contract a variety of insects and slowly build a defense in their early years.
But they go to school without any protection, causing a wave of viruses and a change in data trends.
There have been unusual spikes in RSV – a respiratory infection – in the summer months, when it’s usually a problem in the winter.
In recent months, outbreaks of scarlet fever, or what is known as “Victorian” disease, have broken out across the country.
Quite unusually, a mysterious outbreak of hepatitis (liver inflammation) occurred in children this year.
Research from the British Health and Safety Agency (UKHSA) continues to suggest a link to a previous adenovirus infection.
“But the investigation continues to uncover the exact reason for the increase in cases,” said Dr. Renu Bindra, Senior Medical Advisor at UKHSA.
Professor Simon Taylor-Robinson, a hepatologist at Imperial College London, said: “Given their seasonality, it is possible that children have been isolated from their peers in the past two years and therefore have not contracted the usual childhood viral diseases they build. immunity.
“Therefore, exposure to viruses such as adenoviruses may now be responsible for the more exaggerated symptoms seen by some of these previously isolated children.”
UKHSA said it was investigating whether co-infection with another virus, such as Covid, was the driving force.
“Some of the children with acute hepatitis have recently had a Covid-19 infection,” UKHSA said.
“But in this age group there have been a high number of Covid-19 infections, so this is not unexpected.”
The fallout from the pandemic has led to a drop in vaccination rates among children.
Dr Vanessa Saliba, consultant epidemiologist at the United Kingdom Health and Safety Agency (UKHSA), previously told The Sun: “The disruption caused by the Covid-19 pandemic was the main reason for the decline in childhood vaccine intake seen in recent years has been observed for two years.
“This drop in coverage means we have less protection against infectious diseases such as measles with the risk of epidemics.”
Measles vaccination rates have dropped to their lowest level in a decade, the British Health and Safety Agency (UKHSA) said in February.
The World Health Organization (WHO) says 95% of people need to be vaccinated against measles to keep it under control.
However, the latest data from September showed that only 85.5% of five-year-olds received the two doses of the MMR vaccine, which protects against measles, mumps and rubella.
In recent years, most of the public health resources have been dedicated to monitoring Covid.
As a result, other diseases such as monkeypox and tuberculosis may have silently spread, the Independent reported.
In March, UKHSA called on the public and healthcare professionals to help reverse the upward trend in tuberculosis (TB) cases.
Health and Welfare Secretary Sajid Javid said it was “very worrying” to see an increase in cases after “significant progress has been made towards tuberculosis eradication in England over the past decade.”
The incidence of tuberculosis has been on the rise since 2019, and although it stopped in 2020 due to Covid, it has been on the rise again since then.
Babies, toddlers and young children are at a greater risk of contracting tuberculosis than healthy adults.
The World Health Organization warned in early June that monkeypox may have been spreading in communities for “months or maybe a few years”.
The bug was spotted hundreds of times in May in countries where it is not normally seen.
This includes Great Britain. Almost all cases, however, involved men between the ages of 30 and 40.
Dr Babak Ashrafi, Clinical Director of ZAVA UK, said: ‘Investigations are underway into how the virus spread and what triggered the outbreak in the first place.
“Did the Covid-19 virus and / or lockdowns play a role?
“There is no evidence that the monkeypox virus is linked to Covid-19 or any of the vaccines.
“However, the easing of the lockdown and the return to international travel may have reopened the doors to the transmission of new infections.”
