Figure 1From: Ten-year trends in HIV prevalence among visitors to public health centers under the National HIV Surveillance System in Korea, 2000 to 2009 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.Back to article page
