“…The weakest positive sample could still be detected at a dilution of 1/40. This approach has previously been used for anti-HIV positive sera [4]. All sera in reactive pools were retested singly by Ortho Diagnostics EIA and single reactive sera were confirmed by recombinant immunoblot assay (RIBA, Ortho Diagnostics) where the criteria for a reactive sera is that at least two bands have equal or greater intensity to the human IgG control band.…”

SUMMARYA total of 3522 samples of serum, collected anonymously from women attending an antenatal clinic, was tested for hepatitis B surface antigen and antibody to hepatitis C. The prevalence of anti-HCV was low; only five confirmed positives were found (0 14 %). The prevalence of hepatitis B overall was 0-56%, but was 1-04% in women from immigrant groups. Hepatitis B carriage is therefore four times more common than hepatitis C carriage in the antenatal population comprised of various ethnic origins. The patterns of infection in the two viruses are reversed, hepatitis B being more common in Asian, S.E. Asian and West Indian mothers and hepatitis C being more common in mothers of white Caucasian origin. Routine antenatal screening for anti-HCV is discussed.

“…The wide range of HIV seroprevalence rates observed in the hospitals reflects the variation in distribution and manifestations of the HIV epidemic between and within different geographical areas. A similar disparity in levels and distribution of HIV infection was found in the USA in the hospitals participating to the Sentinel Hospital HIV Surveillance System (17,18), as well as in European studies conducted among unselected patients attending health care services by testing pooled residual laboratory sera (2,4,5). These studies, however used different inclusion criteria and were conducted during different years, rendering comparisons difficult.…”

An anonymous unlinked seroprevalence study of human immunodeficiency virus (HIV) infection was performed by testing pools of ten sera remaining from specimens submitted consecutively to clinical pathology laboratories at 18 Italian public hospitals during four consecutive days in April 1991. Sera from positive pools were retested individually by three different enzyme immunoassays (EIAs) and considered positive if reactive by all three assays. Only the sera with discordant EIA results were retested by Western blot. Of a total of 22,590 sera, 278 were HIV positive (1.2%). The highest rates were seen in hospitals located in metropolitan areas (1.5%), in infectious disease departments (28%) and in drug addiction treatment units (28%); among men aged 21-30 (4.6%) and 31-40 years (4%); and among women aged 21-30 years (1.6%). The distribution of seropositive patients by gender and age group suggests an increasing role of heterosexual transmissions of the infection. The presence of anti-HIV antibodies in sera from patients of both sexes, in all age groups, and from all clinical settings reinforces the need for health care workers to adhere to universal precautions issued to prevent occupational bloodborne infections.
