The number of new coronavirus cases in the United States rose by nearly 48,700 on Friday. For seven consecutive days, the daily number fell below 50,000 as the nation gradually descended from a summer of eruptions.
The coronavirus infected more than 5.6 million people in the United States on Saturday, according to Johns Hopkins University, which is roughly a quarter of the cases reported worldwide. The U.S. recorded at least 1,100 deaths on Friday, bringing the death toll over 175,000.
"I think we've been seeing progress in the past four weeks. I hope the progress continues, but I don't think any of us should turn away from realizing that the key that each of us realize is that we are want to make sure that Covid stops with us. " "Robert Redfield, director of the Centers for Disease Control and Prevention, told reporters on a conference call Friday.
According to a CNBC analysis of the data collected by Johns Hopkins, more than 10 states are reporting growing cases based on a seven-day moving average to smooth daily reporting. Many of the states are in the Midwest, including Iowa, Kansas, Illinois, North Dakota, and South Dakota.
While new U.S. cases are down nearly 17% from a week ago, based on a seven-day average, public health experts recently questioned the accuracy of some declines due to reduced testing. Coronavirus testing in the US has also been hampered by serious delays.
"I've really come to believe that testing has entered a real, new, emerging crisis and it makes it difficult to know where the pandemic is slowing down and where is not," said Dr. Ashish Jha, director of the Harvard Global Health Institute, said in an interview with CNBC earlier this month.
The decline is due to universities and schools across the country grappling with the safe return of students to class. Some universities, like the University of North Carolina at Chapel Hill and the University of Notre Dame, have been struggling to contain coronavirus outbreaks since their campus reopened.
"The virus is a formidable enemy," said Notre Dame President Rev. John Jenkins on Tuesday. "It won last week." The university announced Tuesday that it would pause face-to-face elementary school classes for at least two weeks after the number of cases where officials were involved in off-campus parties just a week after the fall semester began rose sharply.
However, President Donald Trump urged universities to continue their plans to reopen during a press conference at the White House Wednesday, saying, "There's nothing like being with a teacher than sitting on a computer board."
"The iPads are wonderful, but you won't learn how to be there like that," Trump told reporters.
Trump reiterated that younger people are less susceptible to serious illness from Covid-19 than older adults, despite public health officials warning that infections could last long-term and that not all young adults are immune to serious consequences.
Around 80% of deaths in the US from February 12 to May 18 were 65 years of age or older, according to a July report from the Centers for Disease Control and Prevention. The agency also said in June that the hospitalization rate for people who tested positive for the coronavirus in their 20s is below 4%.
