Health officials warned that models have shown the B.1.1.7 strain of the virus has the potential to increase “the U.S. pandemic trajectory in the coming months” and “warrants universal and increased compliance with mitigation strategies, including distancing and masking.”
Increased vaccinations may need to be achieved to fight the virus, the CDC said.
“The modeled trajectory of this variant in the U.S. exhibits rapid growth in early 2021, becoming the predominant variant in March. Increased SARS-CoV-2 transmission might threaten strained health care resources, require extended and more rigorous implementation of public health strategies, and increase the percentage of population immunity required for pandemic control,” said the CDC.
UK authorities said last year that the new variant of the virus was the reason for the increase in infection rates in London and southeastern England. But they said there’s no evidence that the variant makes people sicker.
The CDC, in its update, did not appear to recommend any new mitigation strategies.
“Further, strategic testing of persons without symptoms of COVID-19, but who are at increased risk for infection with SARS-CoV-2, provides another opportunity to limit ongoing spread,” according to the CDC. “Collectively, enhanced genomic surveillance combined with increased compliance with public health mitigation strategies, including vaccination, physical distancing, use of masks, hand hygiene, and isolation and quarantine, will be essential to limiting the spread of SARS-CoV-2 and protecting public health.”
Previously, the CDC noted that so far, there have been a number of mutations to the virus.
