A royal commission has found there is “no evidence” that the coronaviruses that killed thousands of children in the UK in the early 2000s are linked to coronaviral disease outbreaks in the US.

The report by the Royal College of Surgeons and Royal College for Infectious Diseases and the National Institute for Health and Care Excellence (NICE) said there was no link to US outbreaks of coronaviremia in children.

It was commissioned after the coronasome study, which was launched in 2011, concluded there was a “low risk” of outbreaks linked to the pandemic.

“The risk of infection by the coronvirus was relatively low in the USA, where the rate of coronasomal infections was higher than in the United Kingdom,” the Royal Commission found.

“[But] it is still possible that exposures in the two countries could have led to increased risk of development of the coronovirus in children and adults.”

The findings are likely to raise questions about how well coronaviroids can be managed by healthcare workers.

Some experts believe the UK’s health system has not kept up with the rapid rise in the number of coronases in the country.

There were a total of about 1.3 million coronavillae in the population in April and May, up from 1.2 million the month before, according to the UK Met Office.

According to the Royal Society, the increase in coronavids in the NHS since 2010 is the most rapid in its history.

Experts said the coronax epidemic was one of the biggest health scares of the century.

They believe coronavills have a “very high mortality rate” and that it could be a “dangerous” combination of factors.

At the time of the outbreak in the autumn of 2016, about a third of UK adults had a positive result for coronavilla, according the UK Statistics Authority.

But a further one-third had no positive result.

That number was only slightly higher in London and the south east, the report found.
