@Bob_Wachter @sri_srikrishna Yes, but not a substitute for universal masking when you sometimes must remove the mask for hydration, food, or medicine. More vulnerable people, in particular, may have less or no ability to go for extended periods without doing so, but its an issue that affects almost everyone.
@Bob_Wachter@sri_srikrishna是的，但当你有时需要去除面膜以补充水分、食物或药物时，它并不能替代通用面膜。尤其是更易受伤害的人，如果不这样做的话，他们可能没有或没有能力长时间外出，但这是一个几乎影响到所有人的问题。
