As novel coronavirus cases in the U.S. approach nearly four million, with over 142,000 deaths, 13 states have reported over 20 percent rises in new infections over the past couple of weeks, according to data compiled by Johns Hopkins University.
The percentage increase for each state was calculated by comparing new cases numbers for the weeks of July 8-14 and July 15-21.
Mississippi saw the largest jump in the country over the last 14 days. The state reported a 7,982 new cases in the week July 15-21, a 50.6 percent increase on the 5,297 new cases reported the previous week.
Earlier this month, Mississippi Gov. Tate Reeves announced the state would be pausing any plans to reopen following a spike in cases.
"Things are getting worse, not better," he said at a news briefing. "It's not that our current rules are too loose. Our challenge is that our people aren't following even the simplest of rules. Additional orders are useless if people will not follow what we have in place now."
Over 14.9 million people across the globe have been infected since the virus was first reported in Wuhan, China, including 3.9 million in the U.S. More than 8.4 million globally have reportedly recovered from infection, while over 617,200 have died as of Wednesday, according to the latest figures from Johns Hopkins University.
