Omicron Subvariant May Cause More Damage, Not Less

“New research on the Omicron subvariant of the coronavirus has suggested the pathogen could be changing how it attacks the human body — shifting from infecting respiratory systems to increasingly targeting the brain,” the South China Morning Post reports.

“The findings challenge the common belief that viruses usually evolve to become less pathogenic.”

Associated Press: “Moves by several countries to mandate COVID-19 tests for passengers arriving from China reflect global concern that new variants could emerge in its ongoing explosive outbreak — and that the government may not inform the rest of the world quickly enough.”
