W. Strecker et al., EPIDEMIOLOGY AND CLINICAL MANIFESTATION OF HIV-INFECTION IN NORTHERN ZAIRE, European journal of epidemiology, 10(1), 1994, pp. 95-98
1275 patients were evaluated for HIV-1+2 seroprevalence and its associ
ation with clinical symptoms of HIV infection. Of 667 apparently healt
hy subjects, 8.2% had anti-HIV-1 antibodies. In 465 patients with clin
ical signs of AIDS, 39.4% were seropositive. 143 patients with miscell
aneous symptoms had positive predictive values for HIV infection betwe
en 67% (vaginal ulcerations) and 20% (profound pyogenic abscesses). Th
e WHO definition for AIDS had a specificity of 78.3%, a sensitivity of
72.2% and a predictive value of 61.6%.
