New strain of Delta variant detected in the US

A brand new sub-lineage of the extremely contagious Delta variant that’s spreading all through the UK has been detected in the United States, well being officers mentioned Wednesday.

AY.4.2 is being carefully monitored in the UK after British well being officers revealed that the new variant — reported to be 10 to fifteen p.c extra transmissible that Delta — had been linked to a rising quantity of COVID-19 infections there.

Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, confirmed throughout a COVID-19 briefing Wednesday that AY.4.2 has been discovered in the US.

Walensky mentioned the new variant, which she acknowledge has “drawn some attention in recent days,” has not been linked to any clusters inside the nation.

“We have, on occasion, identified this sub-lineage here in the United States, but not with recent increased frequency or clustering to date,” Walensky mentioned.

“At this time, there is no evidence that the sub-lineage AY.4.2 impacts the effectiveness of our current vaccines or therapeutics and we will continue to follow.”

She added: “In the United States, Delta remains the dominant variant with more than 99.7% of sequence cases in the country being caused by Delta.”

A CDC spokesperson instructed The Post that AY.4.2 is “very rare” in the US — with “less than 10” instances discovered to date, which accounts for lower than 0.05 p.c of sequenced instances.

The CDC has not confirmed in what US states AY.4.2 has been detected.

“There is no evidence that the sub-lineage AY.4.2 impacts the effectiveness of our current vaccines or therapeutics,” Dr. Rochelle Walensky acknowledged.

Former Food and Drug Administration Commissioner Scott Gottlieb tweeted about the variant over the weekend, calling for “urgent research to figure out if this delta plus is more transmissible” or has “partial immune evasion.”

Experts instructed the UK’s Financial Times that AY.4.2 seemed to be 10 to fifteen p.c extra transmissible than the unique Delta variant.

British well being officers mentioned final week they had been carefully monitoring AY.4.2 after the latest data confirmed 6 p.c of COVID instances in the nation had been linked to the new variant.

AY.4.2 has not been labeled as “under investigation” or a “variant of concern” in the UK.

Experts mentioned there was no early indication that AY.4.2 would turn out to be the dominant variant and that it was unlikely to alter the present COVID image.

“Discovery of new variants is of course important to monitor, but it doesn’t indicate that that new variant is going to be the next one to replace Delta,” Oxford Vaccine Group chief Andrew Pollard instructed BBC radio on Wednesday.

“Indeed even if it does, Delta is incredibly good at transmitting in a vaccinated population and a new one may be a bit better but it’s unlikely to change the picture dramatically from where we are today.”
