Figure 1

The trend in HIV prevalence or positive rate by reason for HIV testing. (A) General Group: Health checkup (P = 0.134), Medical record (P = 0.776), Prenatal checkup (P = 0.623), Others (P = 0.039) (B) HIV ISG (HIV infection suspected group): Referral by doctor (P = 0.226), Voluntary (voluntary test taker, P = 0.007), (C) HIV TRG (HIV test recommended group): TB patients (P = 0.069), Prisoners (P = 0.003, excluded 2000 and 2001), (D) Total (a total HIV test takers, P = 0.012), Voluntary (voluntary test takers, P = 0.007), and Anonymous (anonymous test takers, P < 0.001). HIV TRG included partners of HIV-infected individuals, but it was not presented in figure C, because their prevalence was much higher compare to those of other groups (the number of HIV-infected individuals/the number of HIV-tested individuals, 2000: 2/3, 2001:4/6, 2002: 2/5, 2003: 1/6, 2004: 2/8, 2005: 5/27, 2006: 2/18, 2007: 4/24, 2008: 1/39, 2009: 9/36). In figure D, anonymous test takers present HIV positive rate instead of HIV prevalence. *P-value by score test for trend of HIV prevalence for ten years.
