Prime Minister Scott Morrison has ordered an urgent investigation into a coronavirus-linked illness suspected to have killed at least three children in the US.

Chief Medical Officer Brendan Murphy has been told to gather medical advice on Kawasaki disease from Australia and overseas before political leaders meet later this week.

The symptoms of the COVID-19 related illness are akin to Kawasaki disease and have been seen in almost 80 American children.

“I will leave that to the medical experts to provide that advice, but what they have said is there are no known cases or examples in Australia at this stage,” said Minister for Health Greg Hunt.
