Children worldwide present rare virus reaction
Ratings of UK and US children have already been affected by a good rare inflammatory disease associated with coronavirus.
Numerous children have also been diagnosed with the condition - that may cause symptoms similar to toxic shock syndrome - elsewhere in Europe.
Up to 100 UK children have already been affected. Some have wanted intensive care while others recovered quickly.
In April, NHS doctors were told to look out for a rare but dangerous response in children.
This is prompted by eight children becoming ill in London, including a 14-year-old who died.
Doctors said all 8 children had comparable symptoms when they were admitted to Evelina London Children's Hospital, including a higher fever, rash, red eyes, swelling and basic pain.
Most of the children had no main lung or difficulty in breathing, although seven were put on a ventilator to greatly help improve center and circulation issues.
Doctors are describing it all as a "new phenomenon" similar to Kawasaki disease shock syndrome - a rare state that mainly affects children under the era of five. Symptoms include a rash, swollen glands in the neck and dry and cracked lips.
But this new syndrome can be affecting teenagers up to the age of 16, with a minority experiencing serious complications.
Dr Liz Whittaker, clinical lecturer found in paediatric infectious diseases and immunology, at Imperial University London, said the actual fact that the syndrome was occurring in the center of a good pandemic, suggests both are linked.
"You've got the Covid-19 peak, and three or four weeks soon after we're seeing a peak in this new phenomenon making us feel that it's a post-infectious phenomenon," she said.
This means chances are to be something linked to the build up of antibodies after infection.
Prof Russell Viner, president of the Royal College of Paediatrics and Child Health, said the majority of children who've had the problem have taken care of immediately treatment and are getting better and starting to go home.
The syndrome is "exceptionally rare", he said.
"This shouldn't stop parents letting their children exit lockdown," Prof Viner added.
He said understanding more about the inflammatory disease "might explain so why some children become extremely ill with Covid-19, as the majority are unaffected or perhaps asymptomatic".
Children are idea to create up just 1-2% of all cases of coronavirus contamination, accounting for under 500 admissions to hospital.
Michael Levin, professor of paediatrics and international child health and wellbeing in Imperial, explained that almost all of the children tested negative for coronavirus, but tested great for detection of antibodies.
"So we really feel that the biology of the disease, somehow involves an unusual immune response to the virus," he said.
On the other hand Prof Levin said there is "a vast amount to learn" about the reaction, which had simply been known about for two to three weeks.
Children look like affected up to six weeks after they have already been infected with the virus, that could explain the looks of the brand new syndrome some weeks following the peak of UK situations.
What is the problem elsewhere on the planet?
There were similar cases in america, Spain, Italy, France and holland.
At least 15 US states want in to the rare condition, according to New York governor Andrew Cuomo.
Out of 82 diagnosed instances of the inflammatory syndrome in New York, 53 children tested positive or had antibodies for Covid-19.
The Centers for Disease Control (CDC) in america is defined to issue an alert and updated definition of the syndrome to healthcare providers this week.
Meanwhile, according to a study by doctors found in northern Italy, 10 children have already been affected by the condition.
All 10 of the kids in the analysis were admitted to a hospital on Bergamo - the location at the center of the worst outbreak on Italy - between mid-February and mid-April, and recovered.
The children, who remain seven years old, tended to possess severe symptoms such as for example heart issues and signs of toxic shock syndrome. They also needed more treatment with steroids.
In antibody tests on the kids, eight appeared to have previously had the coronavirus as the other two had not. Even so, swab tests for the virus are not regarded as useful because the reaction will occur weeks after infection.
Dr Lucio Verdoni, report writer and doctor at the Hospital Papa Giovanni XXIII found in Bergamo, said: "Although this complication remains incredibly rare, our study provides further evidence about how the virus could be affecting children."
Child health experts in the UK say it might not be something just affects children.
They are now dealing with researchers in america and across Europe to learn more in what they have called paediatric inflammatory multisystem syndrome or (PIMS-TS).
