Kids COVID risk all in vein

Better blood vessel health is one of the main reasons children have been protected from the worst of COVID-19, an international literature review has found.

Researchers from The University of Melbourne found damage to certain cells in the heart, lymph system and blood vessels was linked to more severe cases of coronavirus.

Professor Nigel Curtis said COVID-19 was different to other respiratory illnesses, which tend to affect adults and children more equally.

“Even children with the usual risk factors for severe infections, such as immunosuppression, are not at high risk of severe COVID-19 disease,” he said.

On the other hand, damage to blood vessels explains why COVID-19 severity rises steeply after 70 years of age. COVID-19 can infest the endothelial cells and cause blood vessel inflammation.
