  1. a) n and %: crude number and weighted prevalence of MSM who declared screening for hepatitis C during the previous year in the reported category. For instance, 1093 MSM who defined themselves as homosexual reported HCV screening during the previous year; the prevalence of HCV screening during the previous year among the MSM who defined themselves as homosexual is estimated to be 43.2% [39.9–46.7]
  2. b) undiagnosed HCV or HIV (MSM unaware of their HCV or HIV status): HCV or HIV status confirmed by virologic analysis after respondent reported “negative” or “not certain of being negative” or “I don’t know” to the question on “status” in the self-administered questionnaire.
