HIV1 infection in extra-European students in Turin (Italy): epidemiologic pattern and risk factors.

The authors studied a population of 5634 students from various continents to determine possible correlations between risk factors and seroprevalence of HIV infection. In the African sample the seroprevalence rate was 3.5%; the age range from 19 to 30 years was most affected; prevalence differences between the sexes were slight (3.5% for the males vs 3% for the females); the evaluation of the medical history (STDs, malaria, TB and hospital stays) showed no statistically significant association with HIV-1 infection; the central-eastern Africa significantly appeared the most affected.
