In a Feb. 10 interview for the BBC’s Newscast podcast, Peacock said that the U.K. variant had “swept the country,” noting it’s currently responsible for the majority of new cases in England. But then, she warned, “It’s going to sweep the world, in all probability.” At the current time, the U.K. variant, known as B.1.1.7., has been detected in more than 70 countries, according to The New York Times.

Peacock stressed that the key to containing the virus is closely monitoring how it’s adapting, and continuing to do so even once this acute phase of the pandemic is over and life has returned to normal. “Once we get on top of [the virus] or it mutates itself out of being virulent—causing disease—then we can stop worrying about it,” she said. “But I think, looking in the future, we’re going to be doing this for years. We’re still going to be doing this 10 years down the line, in my view.” And for a stateside prediction about our return to normalcy, check out Dr. Fauci Says This One Thing Could Stop Us From Getting Back to Normal. While all viruses mutate in order to transmit and survive, most of these differences are insignificant. At the moment, however, there are three variants that are particularly concerning experts: one originating from Brazil, one from South Africa, and the U.K. strain. In all cases, the concern is that mutations have occurred that may make the virus at least partially resistant to vaccines and treatments, or faster to transmit. Currently, as of Feb. 11, there are 981 reported cases of the U.K. variant in the U.S., spread across 37 states. In a new study out of the Scripps Research Institute in La Jolla, California, which has not yet been peer-reviewed, researchers found that cases of this highly contagious COVID strain are doubling every 10 days.ae0fcc31ae342fd3a1346ebb1f342fcb Research by scientists on the New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG) in the U.K. suggests that the B.1.1.7. variant spreads between 30 percent and 70 percent faster than others. “What’s really affected us at the moment is transmissibility,” said Peacock. This increase in the number of cases, rather than their severity, is what’s placed the U.K. medical system under huge strain since December.

Their findings support the prediction from the Centers for Disease Control and Prevention (CDC) that the strain will become the dominant type of COVID in the U.S. come March. “Our study shows that the U.S. is on a similar trajectory as other countries where B.1.1.7 rapidly became the dominant SARS-CoV-2 variant, requiring immediate and decisive action to minimize COVID-19 morbidity and mortality,” the authors note. “It is almost certainly destined to become the dominant SARS-CoV-2 lineage by March, 2021 across many U.S. states.” And for more on keeping yourself safe from COVID-19, check out This Medication Could Slash Your Risk of Dying From COVID, Experts Say.
