Combined there was an average of 6800 participant entrances into the lavatories daily.Primary outcome measure The primary outcome measure is the proportion of soap usage to the number of entries into the lavatories.Results Hand-washing rates were positively related to both H1NI coverage in blogs and the news; however, these relationships were stronger for men than for women.Conclusions Hand washing with soap increases proportionally to the frequency of media key words related to H1N1. Women's hand washing was more strongly associated with incidence of media keywords than men's.
