Participant category (no.) M/F Age at death, y (range)† Year of death (range)† Mean CD4/μL (range)† AIDS? B19 positive, 
no. (%) PARV4 positive, no. (%)

(167–496) N 6 (55) 6 (55)
HIV+ MSM (13) 13/0 39 (28–49) 1993 (1990–1996) 25

HIV– IDU (12) 10/2 35 (24–49) 1999 (1992–2005) ND NA 8 (67) 1 (8)
Hemophilia (2) 2/0 22, 26 1994, 1995 0 Y 0 1 (50)
Low-risk control§ (8) 3/5 54 (28–89) All 2005 ND NA 8 (100) 0

*IDU, injection drug user; M, male; F, female; Y, yes; N, no; MSM, men who had sex with men; ND, not done; NA, not applicable.
†Values are means (ranges) or individual values for those with hemophilia.
‡These study groups overlap with the previously analyzed HIV-positive group (8), restricted to those in whom parenteral risk factors for infection have been identified.
§Previously described in (8).
