Doctors in the United Kingdom warned all to look out for a rare but dangerous reaction in children which be linked to the coronavirus infection.
An urgent alert sent out to GPs said that intensive care units in London and other areas of the UK have been treating severely sick children with strange symptoms.
Some of these symptoms include "multi-system inflammation" with flu-like indicators. Unusually only some, of the cases tested positive for coronavirus.
NHS England medical director Stephen Powis said they had become aware of reports of rare, severe illness in children. "It's only in the last few days that we have seen those reports. We have asked our experts to look into this as a matter of urgency." Authorities at NHS England went onto say that there was "a growing concern" that a coronavirus-related inflammatory syndrome is emerging in children in the UK or that there may be another, as yet unidentified, infection linked to these cases.
They went onto say that these young patients of varying ages were extremely ill. They had similar features to toxic shock syndrome, which can include a high temperature, low blood pressure, a rash and difficulty breathing.
Some also had gastrointestinal symptoms - tummy pain, vomiting or diarrhoea - and inflammation of the heart, as well as abnormal blood test results.
The alert advises these cases need urgent treatment.
