All students in residence halls receiving intervention (ii) will be provided with a comprehensive hand hygiene education component in addition to mask use. The educational component will include posters and pamphlets that provide background information on transmission of influenza, an explanation of the effectiveness of hand hygiene for reducing transmission, and guidelines for proper hand hygiene, including the need for hand hygiene at critical locations throughout the residence halls. The hand washing campaign will consist of posters on bulletin boards and weekly email hand hygiene reminder messages to participants in the intervention residence halls. The educational component of the study will include a video for both the control arm and the intervention arms. The control video will address information on influenza and an overview of the study. The intervention video will address both information on influenza and an overview of the study, in addition to hand hygiene education and the use of hand sanitizer and the use of face masks. Both videos are available on the website (www.mflu.org) and on Survey Monkey linked to the consent form.
