The Lost Summer of 2020 drew to a close Monday with many big Labor Day gatherings canceled across the U.S. and health authorities pleading with people to keep their distance from others so as not to cause another coronavirus surge like the one that followed Memorial Day. … The U.S. had about 1.6 million confirmed COVID-19 cases around Memorial Day, before backyard parties and other gatherings contributed to a summertime surge. It now has more than 6.2 million cases, according to the count kept by Johns Hopkins University. Deaths from the virus more than doubled over the summer to nearly 190,000.
