美国20多个州现要求民众在公共场所戴口罩

美国仅在过去一个月就有超过100万例冠状病毒感染确诊，使本周初确诊病例总数突破300万大关。 有口罩强制规定的州名单包括：加州、康涅狄格州、特拉华州、伊利诺伊州、堪萨斯州、肯塔基州、缅因州、马里兰州、马萨诸塞州、密歇根州、内华达州、纽约州、新泽西州、新墨西哥州、北卡罗来纳州、俄勒冈州、宾夕法尼亚州、罗德岛州、弗吉尼亚州、华盛顿州和西弗吉尼亚州。 德克萨斯州和俄亥俄州也出台了类似的规定，但仅限于确诊病例率超过政府门槛的县。夏威夷州也有一项全州范围的口罩要求，不过适用于重要企业的客户和员工。两个受灾最严重的州--佛罗里达州和亚利桑那州--仍然没有全州性的规定。

The U.S. has recorded more than 1 million coronavirus infections over the past month alone, pushing the total number of confirmed cases past the 3 million mark earlier this week. The list of states with mask mandates includes California, Connecticut, Delaware, Illinois, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Nevada, New York, New Jersey, New Mexico, North Carolina, Oregon, Pennsylvania, Rhode Island, Virginia, Washington and West Virginia. Similar mandates in Texas and Ohio are limited to counties where the coronavirus case rate surpasses government thresholds. Hawaii also has a statewide mask mandate, which applies to customers and staff at essential businesses.Two of the worst-hit states — Florida and Arizona — still don't have statewide mandates.  source
