According to the CDC, the answer is yes: "Wearing cloth face coverings is an additional public health measure people should take to reduce the spread of COVID-19. CDC still recommends that you stay at least 6 feet away from other people (social distancing), frequent hand cleaning and other everyday preventive actions. A cloth face covering is not intended to protect the wearer, but it may prevent the spread of virus from the wearer to others. This would be especially important if someone is infected but does not have symptoms."
