“I am asking you to just hold on a little longer, to get vaccinated when you can, so that all of those people that we all love will still be here when this pandemic ends,” she said at a White House briefing.
According to a New York Times database, the seven-day average of new virus cases as of Sunday was 63,000, a level comparable to late October, and up from 54,000 a day two weeks earlier, an increase of more than 16 percent. Similar upticks in the past over the summer and winter led to major surges in the spread of disease, Dr. Walensky said.
The wave of new cases comes as the nation rapidly broadens eligibility for vaccines, the average number of daily shots continues to rise, and a new C.D.C. report released Monday confirmed the findings of last year’s clinical trials that vaccines developed by Moderna and Pfizer are highly effective against Covid-19 disease. The report documented that the vaccines work to prevent symptomatic and asymptomatic infections under real-world conditions.
The seven-day average of vaccines administered hit 2.7 million on Sunday, a slight increase over the pace the previous week, according to data reported by the C.D.C. But worrisome hot spots continue popping up.
In nine states over the past two weeks, virus cases have risen more than 40 percent, the Times database shows. Michigan led the way with a 133 percent increase. The Northeast has also seen a troubling rise in virus cases. Connecticut reported a 62 percent jump in cases over the past two weeks, and New York and Pennsylvania both reported increases of more than 40 percent.
Michigan’s spike has not been traced to any one event, but epidemiologists have noted that cases started to jump after the state eased restrictions for indoor dining on Feb. 1 and lifted other restrictions in January. Other hot spots included North Dakota, where cases rose by nearly 60 percent and Minnesota, where cases have jumped 47 percent. Of those states, North Dakota is the only one without a current mask mandate.
Dr. Walensky on Monday described “a feeling of nausea” she would experience last year when, as a doctor at a Boston hospital, she saw the corpses of Covid-19 patients piled up, overflowing from the morgue; and when she stood, “gowned and shielded,” as the last one in a patient’s room before they died alone, without family.
