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 t o determine possible correlations between risk factors and seroprevalence o f HIV infection. In the African sample the seroprevalence rate was 3.5%; th e age range from 19 to 30 years was most affected; prevalence differences b etween the sexes were slight (3.5% for the males vs 3% for the females); th e evaluation of the medical history (STDs, malaria, TB and hospital stays) showed no statistically significant association with HIV-1 infection; the c entral-eastern Africa significantly appeared the most affected.
