Amongst our participants, mask use, as an infection control strategy was extremely unpopular. In many western settings, where medical mask/respirator use is generally restricted to the hospital setting, it is not unanticipated that people would associate embarrassment and social stigma with the use of these products. At the University, it is extremely rare to see a student wearing a medical mask. This maybe because students believe that masks are uncomfortable, inconvenient and unnecessary. Habit is an important influence on routine behaviour [25] , including hygiene behaviour [26] , such that despite their best intentions people may find it difficult to implement new hygiene measures during a pandemic if they have not previously made these a habit.
