  1. 95% CI: 95% confidence interval.
  2. 1 Only those people who reported that they had already heard of hepatitis B (n = 8,686) were asked questions about knowledge of hepatitis B transmission modes; all participants in the study group were asked all other questions (n = 9,014).
  3. 2 The wording of questions was different depending on the virus, as follows: “Sharing a needle while injecting drugs” for HBV and “When injecting using a needle that has already been used” for HIV.
  4. 3 The correct answer was “yes” for questions (1), (2) and (4) and “no” for question (3).
  5. 4 These questions were not asked for HIV.
  6. 5 The wording of questions was different depending on the virus, as follows: “Do you personally know one or more people in your circle of family and friends who currently has or who had Hepatitis B?” / “Do you personally know one or more people in your circle of family and friends who is seropositive or who has AIDS?. The choice of answers was also different (yes, no, did not know for HBV; yes, perhaps, no, did not know for HIV).
