US Begins to Reopen, but Coronavirus Concerns Remain High Ken Bredemeier WASHINGTON - A key U.S. coronavirus official voiced serious concerns Sunday about Americans failing to take the highly contagious disease seriously enough as the country begins to reopen its commercial and recreational life. Dr. Deborah Birx, the White House coronavirus response coordinator, told the "Fox News Sunday" show, "I'm very concerned about people going out without social distancing," staying at least two meters away from others to curb the chances of passing on the disease. "We have to have social distancing if they're in groups," she said. "They don't know if they're asymptomatic" and could unwittingly pass on the virus. "We want to urge people to hike, golf, play tennis," but to do it safely by maintaining an appropriate distance from other people, she said. With the U.S. world-leading coronavirus death toll likely to top 100,000 within a week, President Donald Trump erroneously claimed on Twitter, "Cases, numbers and deaths are going down all over the Country!" Cases, numbers and deaths are going down all over the Country! -- Donald J. Trump (@realDonaldTrump) [1]May 24, 2020 In some states, the number of new cases has diminished, but not everywhere. Authorities say the number of new cases is especially concerning in two of the country's biggest cities, Los Angeles and Chicago, along with Washington, the national capital. Health experts say the death toll could reach more than 140,000 by early August. References 1. https://twitter.com/realDonaldTrump/status/1264564734860427265?ref_src=twsrc%5Etfw .
