Retrospective surveillance of HIV prevalence in blood donors can help in the selection of the best social group for blood donation in Mali.
The National Centre for Blood Transfusion, Bamako, Mali has collected data that characterizes trend in HIV prevalence over 10 years by gender, age, occupation, marital status and donor category. These data help to describe national HIV prevalence and assist in formulating blood donation policies. Donations from 1993 to 2002 were categorized by donor age (decade), occupation (student, military and other), marital status (single, married and other), gender and donor status (volunteer, occasional and family). Comparisons were made using conservative estimates of donation frequency/donor category. Donations increased by more than 400%. By 1999, increased HIV prevalence in donations from women was consistently present. Donations from the age group of 30-39 years showed an increased prevalence beginning in 2000, which by 2002 was almost 10 times greater than in the low-prevalence (<20 years) group (5.9 vs. 0.6%). By 2000, both categories - students and military were less likely to be HIV positive than those from other occupational categories, and donations from married persons were less likely to be HIV positive by 1997. The highest prevalence was observed in the 'occasional' donor category, which increased to >14% by 2001; volunteer donation HIV positive peaked at 2.3% in 1999. HIV prevalence in blood donations in Bamako, Mali, demonstrates important trends from 1993 to 2002. The prevalence of > 14% in donations from occasional donors and significant trends by decade, gender, marital status and occupation argue for increased analysis of the blood donor population to improve blood safety and to understand the demographics of HIV infection in Mali.
