Coronavirus cases in the United States have been slowly ticking up since the Memorial Day holiday, according to a CNBC analysis of data compiled by Johns Hopkins University.
New cases hit a peak of 31,578, based on a seven-day average, on April 10 before steadily falling to an eight-week low of just over 20,600 a day on May 28 — and have been rising ever since. New cases in the U.S. have risen over the last three days in a row with a seven-day average of 21,763 new cases reported Wednesday, the data shows. Research shows that it can take anywhere from five to 12 days for people to show symptoms from the coronavirus, which may explain why U.S. cases are only just now starting to rise after several states reopened beaches and relaxed social distancing rules over Memorial Day, which fell on May 25.
