Face masks.

Some respondents noted the involvement of both the nose and mouth in spreading COVID-19. For example, community members frequently described the risk of an infected person touching their nose and then shaking hands with someone. However, very few respondents discussed the proper technique of wearing a face mask as covering both the nose and mouth. Respondents generally talked about face masks “covering the mouth” or more vaguely mentioning wearing a face mask as a necessary precaution.All respondent groups discussed wearing face masks as particularly important when in gatherings or crowded areas or when social distancing was not possible. Respondents frequently made the link with the modes of transmission, explaining that face masks keep respiratory droplets (or saliva) in (for an infected individual) or out (for an uninfected individual).
