Top disease expert says US in the 'eye of the hurricane' as COVID cases decline amid growing concern over spread of UK variant

• Michael Osterholm, a top disease expert, said Sunday the US is the "eye of the hurricane."
• New daily cases have fallen from their peak earlier this year, but there's still cause for concern.
• Several states have scaled back restrictions, but experts warn such actions are premature.

Dr. Michael Osterholm, the director of the Center for Infectious Disease Research and Policy, warned Sunday about the current state of the pandemic in the US despite a continued decline in new cases.

"We are in the eye of the hurricane right now," he said during an appearance on NBC News' "Meet the Press." "It appears that things are going very well - you even see blue skies. We've been through a terrible terrible year."

According to data analyzed by Johns Hopkins University, the number of new daily cases of COVID-19 diagnosed each day has fallen to less than 70,000 new cases each day - down from a peak earlier this year where new daily cases surpassed 200,000.

Vaccinations have also been accelerated as supply has increased following the emergency authorization of the single-shot Johnson & Johson vaccine in late February. Biden said on March 6 all adult Americans could be vaccinated by the middle of May.

But Osterholm said there was reason for concern over the spread of the more contagious B.1.1.7 variant of the virus, which was first discovered in the United Kingdom and has since "wreaked havoc" on Europe.

About a month ago, 1 to 4% of COVID-19 cases diagnosed in the US were of the B.1.1.7 variant, Osterholm said. But today, about 30 to 40% of new cases were the variant. When cases of B.1.1.7 have reached about 50% of the cases in Europe, the virus begins to "surge," he added, warning of a possible spike in the US.

"Many of these countries have been in lockdown now for two months just to try to control this virus," Osterholm said of European countries hit hard by the variant.

The warnings come amid relaxed public health measures that health officials have warned are premature. States across the US have begun to once again scale back measures to stem the spread of COVID-19. Several states including Texas, Mississippi, Iowa, Montana, and North Dakota, have rescinded mask mandates.

Experts have also warned that spring break vacationers could spread the highly contagious variant in the coming weeks, even as the Centers for Disease Control and Prevention continue to discourage travel.
