Graph showing the number of partners with whom IDUs in Glasgow, recruited during community-wide surveys in 1990–1994, reported needle/syringe sharing (i.e. injected at least once with their used needle/syringe) during the previous 6 months and the geometric distributions used in the model to approximate these data.

Barplot showing the percentage of injecting episodes where a needle/syringe was shared among 837 Glasgow IDUs recruited during surveys conducted in 1990 and 1991–1994, stratified by whether respondents reported having either (a) 1, (b) 2–5, (c) 6–10, or (d) 11–20 sharing partners during the previous 6 months.

Modelled impact of hypothetical lower risk behaviours – in terms of (i) the percentage of IDUs who had shared a needle/syringe per year, (ii) the mean number of needle/syringe sharing partners per year, and (iii) the percentage of injecting episodes shared – on (a) HCV seroprevalence and (b) HCV incidence among current IDUs in Glasgow, 1988–2000.
