A rising number of children are developing rare syndromes that could be linked to coronavirus, the UK national health service and paediatrics specialists have warned.

The UK has seen a small rise in the number of cases of critically ill children presenting "overlapping features of toxic shock syndrome and atypical Kawasaki disease with blood parameters" -- with some of those children testing positive for COVID-19.

It comes after findings that children are as likely as the rest of the population to become infected with COVID-19, although less likely to develop severe symptoms.
