US could be headed for another coronavirus spike, warns Fauci

WASHINGTON (NYTIMES) - Several states have continued steadily lifting restrictions, despite warnings from top federal health officials like Dr Anthony Fauci that new coronavirus cases in the United States have plateaued at a very high level after their drastic drop has stalled and that the country urgently needed to contain the spread of more transmissible variants.

Arizona, California and South Carolina joined a growing list last Friday (March 5) by loosening restrictions, to varying degrees.

Arizona's governor ended capacity limits on businesses but said they must still require masks. South Carolina's Republican governor lifted the state's mask mandate in government buildings, while recommending restaurants continue requiring masking.

California will allow amusement parks and outdoor sports and live events at stadiums to restart from April 1, with reduced capacity and mandatory masks.

"We've just now recently experienced the worst surge," Dr Fauci said during a White House coronavirus briefing, adding that the country had plateaued at between 60,000 and 70,000 new cases per day. "When you have that much of viral activity in a plateau, it almost invariably means that you are at risk for another spike."

The seven-day average for new cases was about 61,000 as at last Friday, the lowest average since last October, according to a New York Times database. But that number was still close to last summer's highest peak.

Fatalities are falling too, in part because of vaccinations at nursing homes. Yet the nation is still routinely reporting 2,000 deaths in a single day.

Dr Fauci warned that the US could be following the same treacherous path that Europe has recently been on.

"They plateaued. And now, over the past week, they saw an increase in cases by 9 per cent - something we desperately want to avoid," Dr Fauci said.

He warned that the virus mutates as it replicates, a process that can be extended when immuno-compromised people are infected. He said that maintaining masking, hand washing and social distancing was urgent.

The B117 variant, first identified in Britain, is spreading so rapidly in the US that data analysis suggests that, as of this week, it has most likely grown to account for 20 per cent of new US cases.

And scientists in Oregon have identified a single case of a homegrown variant with the same spine as B117 that carries a mutation that could blunt the effectiveness of vaccines.

Earlier this week, Texas and Mississippi, both Republican-led states, lifted mask mandates. President Joe Biden denounced those moves as "a big mistake" that reflected "Neanderthal thinking", saying it was critical for public officials to follow the guidance of doctors and public health leaders as the coronavirus vaccination campaign gains momentum.

Other Republicans have been more cautious.

Governor Mike DeWine of Ohio said he would lift all public health measures aimed at curbing the virus crisis, but only once new cases there drop under a certain threshold. In Alabama, Governor Kay Ivey said she would extend the state's mask mandate through April 9.

In Arizona, Governor Doug Ducey has taken what he calls a measured approach, barring local leaders from enacting measures that shut down businesses and allowing major league sports to restart if they receive approval from the state's Department of Health Services.

Among Democrats, Governor Gretchen Whitmer of Michigan said last Tuesday that she was easing restrictions on businesses and would allow family members who had tested negative for the coronavirus to visit nursing home residents.

In California, the state's public health department also loosened some restrictions last Friday, saying that amusement parks could reopen on a limited basis as soon as April 1.

In New York City, limited indoor dining has returned. And last Thursday, Connecticut's governor said the state would end capacity limits later this month on restaurants, gyms and offices. Masks remain required in both places.

Dr Rochelle Walensky, director of the Centres for Disease Control and Prevention (CDC), has implored states not to relax their restrictions yet.

A new report from the CDC found that counties that allowed restaurants to open for in-person dining in the US had a rise in daily infections weeks after. The study also said that counties that issued mask mandates reported a decrease in virus cases and deaths within weeks.
