66 10.0 ASSOCIATED HARMS 10.1 Blood-borne viral infections Notifications of hepatitis B and hepatitis C reported to the National Notifiable Diseases Surveillance System over recent years are shown in Table 57. Both series fluctuate with no clear general trends. HIV notifications are available only until 2004 and show a fluctuation around a low mean across the years shown. Table 57: Total notification of HBV, HCV and HIV, NT 1999-2005 Variable 1999 2000 2001 2002 2003 2004 2005 Hepatitis B (incident) (n) 19 6 3 12 15 8 7 Hepatitis C (unspecified) (n) 187 191 212 201 216 261 198 HIV new cases (n) 5 3 4 8 5 9 na Source: NNDSS & NCHECR The finger prick survey carried out in Darwin and Alice Springs NSPs, auspiced by the National Centre in HIV Epidemiology and Clinical Research,2 found no one with HIV antibodies in the most recent sample (2004, Table 58). Hepatitis C antibody prevalence showed a fluctuating but generally increasing trend from 1998 to 2001, with 50% of the 2001 sample showing HCV antibodies, but declining in 2004 to 9%. Table 58: HIV and HCV antibody prevalence among NSP survey respondents 1998-2004 Variable 1998 1999 2000 2001 2002 2003 2004 HIV antibody (% (n)) 5 (87) 4 (79) 1 (90) 0 (79) 0 (47) 1 (61) 0 (16) HCV antibody (% (n)) 40 (88) 49 (79) 38 (91) 50 (84) 29 (47) 29 (62) 9 (16) Source: NCHECR 10.2 Sharing of injecting equipment among IDU A small proportion of the IDU sample either borrowed (7%) or lent (15%) used needles in the month prior to interview, with larger proportions sharing other injecting equipment (Table 59). The proportion of the IDU borrowing needles continued to decline until 2004, while the proportion lending needles has constantly increased over the years. Of those who borrowed a used needle, two used it after their regular sex partner, one after a casual sex partner, and five after a close friend. No one reported sharing a needle with an acquaintance. 2 Buddle et al., 2003.
