Director of the Centers for Disease Control and Prevention Dr. Rochelle Walinsky said Sunday that the agency was “extremely cautious”. Monitor the new type of COVID-19 known as Deltaplus.
Walensky said the sub-strain of the highly contagious delta variant, known as AY.4.2, was on their radar as it spread across the UK.
“We are following it very carefully. We have a few cases here in the US, but it hasn’t taken off as well as in the UK,” Walinsky. This is what he said on NBC’s Meet the Press.
But Walinsky stressed that it had not been established whether the new variant was more contagious or resistant to vaccines, despite it being linked to a growing number of cases in the UK.
“It contains several mutations on the spike protein that we haven’t yet seen involved in increased transmissibility or decreased ability of our vaccines or treatments to work,” she said.
Walensky said she does not expect the new type to spread, leading to a travel ban from Europe.
Don’t expect that now. We follow the science closely, but we don’t anticipate or study it right now.”
