Advocacy of the use of facemasks by the public as a measure against the spread of COVID-19 is controversial, with some healthcare professionals arguing that the use of a face mask may increase the rate at which people touch their faces, due to readjusting the mask. We assessed the facial touching behaviour of bus passengers in China before and after the outbreak of COVID-19 and found that wearing a face mask does not increase the number of hand-face contacts and is likely, therefore, to have a positive beneficial effect on suppressing the spread of COVID-19 within populations when used in conjunction with social distancing measures.
公众使用口罩作为预防 COVID-19 传播的措施存在争议，一些医护人员认为，由于需要重新调整口罩，人们触摸脸部的频率可能会增加。我们评估了 COVID-19 爆发前后中国公交车乘客的面部触摸行为，发现佩戴口罩不会增加手与脸的接触次数，因此，当与社交距离措施结合使用时，口罩可能对抑制人群中 COVID-19 的传播产生积极的有益影响。
