Raise a handThe 2015 theme for Global Handwashing Day is "Raise a Hand for Hygiene".
This theme is action-oriented and can be used particularly well for
advocacy purposes. The act of raising a hand is one of affiliation. You can, and should, identify yourself as a hygiene champion. This can help create a strong social norm of good hygiene in a school, community, or region.
