@fmokren @DataDrivenMD CDC guidelines for two years were to wear a mask in public to avoid transmitting to others, even if not yet showing symptoms. Nothing about the virus has changed, only politics.
Current guideline is to wear a mask in public if testing positive or exposed even without symptoms.
@fmokren@DataDrivenMD CDC两年来的指导方针是在公共场合戴口罩，以避免传染给他人，即使尚未出现症状。关于病毒的一切都没有改变，只有政治上的改变。
目前的指导方针是，如果检测呈阳性或暴露在公共场所，即使没有症状，也要戴口罩。
