美国有线新闻 CNN 美国多州放宽新冠限制措施（在线收听）

We've talked about how there hasn't been a one-size-fits-all approach when it comes to dealing with coronavirus cases. Different countries have had different levels of restrictions and this has played out the same way in different American states.

Nationwide, the U.S. has seen a decrease in new daily infections since mid-January. At that time, experts said there were more than 270,000 positive tests recorded each day. The latest estimate is that roughly 64,000 positive tests are now recorded daily.

But some health officials are concerned that number has plateaued, meaning the improvement might have stalled. According to Johns Hopkins University, some states are holding steady in their numbers of new cases. Some are seeing decreases continue others are seeing new cases increase.

And what their state governments are requiring varies as well. In Mississippi, for instance, Governor Tate Reeves is allowing businesses to operate at full capacity this week and he's eliminating Mississippi's requirement that people wear masks in public. But in California, where a mask mandate remains, Governor Gavin Newsom is encouraging people to wear two face coverings at the same time.

Despite that divide, several states regardless of whether they're led by Republicans or Democrats are taking some steps to ease their restrictions. Health officials say variants, new mutations of coronavirus may increasingly threaten the U.S., as they have other countries. The Infectious Diseases Society of America says people should continue to wear masks, keep their distance from one another, avoid large gatherings and frequently wash their hands.

我们报道过在应对冠状病毒病例时，没有万能方法。不同的国家有不同程度的限制，在美国不同的州也是如此。

从全美范围来看，自1月中旬以来，美国日增感染病例有所减少。当时，专家表示，每天有超过27万人的检测记录呈阳性。据最新估计，目前每天约有6.4万人的检测呈阳性。

但一些卫生官员担心这一数字已经趋于平稳，因为意味着改善可能受阻。根据约翰霍普金斯大学的数据，有些州的新增病例数量保持稳定。有些州的病例在持续减少，还有些州的新增病例数仍在增加。

各州政府的要求也各不相同。例如，密西西比州州长泰特·里夫斯本周允许企业全面复工，他还取消了该州要求人们在公共场合佩戴口罩的规定。但在加州，佩戴口罩的的规定继续实施，州长加文·纽森甚至鼓励人们戴两个口罩。

尽管存在分歧，但无论由共和党人领导还是民主党人领导，多州都在采取措施以放宽限制。卫生官员表示，冠状病毒的变种、新突变可能会对美国造成越来越大的威胁，就像它们威胁其他国家一样。美国传染病协会表示，人们应该继续佩戴口罩，保持距离，避免大型集会，并经常洗手。
