The number of new daily coronavirus infections in the U.S. continued to rise this past week, driven by upward trends in nearly half the states that have pushed total cases in the country past 7 million. At the same time, a recent study suggests the vast majority of Americans haven’t been exposed, far below what’s required to quell the virus’s spread through “herd immunity.”
Overall, about two-dozen states and territories reported an upward trend in new infections, with some states setting and breaking records in days.
NPR reports that some of the growth in cases is from college students and other larger gatherings of people. The motorcycle rally in Sturgis S.D. is one of the more notable ones that is suspected of driving a surge in infections.
