  1. 1All measurement scales are 1: strongly disagree, 2: disagree, 3: neither agree or disagree, 4: agree, 5: strongly agree.
  2. 2Global risk perception scores represent the mean score on: perceived individual susceptibility, perceived regional susceptibility, perceived severity of the disease and feeling of worry.
  3. *p < 0.05;**p < 0.01; ***p < 0.001 (Student t test).
