Omicron infects young children easier than other variants; loss of smell may be precursor to memory loss

Omicron infects young children easier than other variants; loss of smell may be precursor to memory loss

Fox News
Tuesday, August 2, 2022 10:41 PM GMT

Recent studies show that the omicron variant of coronavirus infects children much easier than any other variant, and that loss of smell may predict memory loss.

The Omicron variant may be more efficient at infecting children through the nose than previous versions of the coronavirus, a small study suggests.

Earlier in the pandemic, children's noses had been less welcoming to the virus that causes COVID-19 than adults' noses. Studies of the original SARS-CoV-2 and some of its variants found the virus was met with stronger immune responses in the cells lining young noses than in adults' nasal-lining cells, and it was less efficient at making copies of itself in children's noses. But recent test-tube experiments mixing the virus with nasal cells from 23 healthy children and 15 healthy adults found the antiviral defenses in kids' noses "was markedly less pronounced in the case of Omicron," researchers reported on Monday in PLOS Biology. They also report that Omicron reproduced itself more efficiently in childrens' nasal-lining cells compared to both Delta and the original virus.
