More infectious COVID-19 delta subvariant spreads fast in the UK

- By NAOMI KRESGE

A more infectious new version of COVID-19’S delta variant is spreading fast in the U.K., accounting for about 12% of the samples gathered in the most recent government survey.

That percentage represents a 2.8% daily growth rate for sub-variant AY.4.2 over the course of the REACT survey, from Oct. 19 to Nov. 5, the researcher­s said.

Still, the new sub-variant seemed less likely to cause symptomati­c COVID-19.

About one in 20 schoolaged children had the virus over the survey period. Prevalence also doubled in people over the age of 65.
