Coronavirus new strain ‘more likely to affect children’ – symptoms to look out for now

But now, scientists have warned the new mutant strain could have more of an affect in young people.

Children were believed to be less affected by COVID-19 due to how the virus enters human cells – via a receptor called ACE2, which is found on many cells in the upper respiratory tract.

The amount of ACE2 a person expresses steadily increases over time, meaning young children have very little.

Professor Wendy Barclay of Imperial College London and a NERVTAG member, explained: “I think on the topic of children we’ve got to be careful about what we say. We are not saying this is a virus that specifically attacks children or is any more specific in its ability to infect children

“But we know that SARS-CoV-2 as it emerged as a virus was not as efficient at infecting children as it was adults.”
