Abstract
After initial assertions that the wearing of face masks was an unnecessary public health tool in the prevention of the spread of Covid-19, the advice coming out of the Centers for Disease Control (CDC) suddenly changed. In early April, the CDC issued new guidelines advising people to wear face coverings in public settings where social distancing is difficult.
摘要
在最初断言戴口罩并非预防新冠病毒传播的必要公共卫生手段之后，美国疾病控制与预防中心（CDC）给出的建议突然改变。4月初，美国疾病控制与预防中心发布了新指南，建议人们在难以保持社交距离的公共场所佩戴面罩。
