Seasonal migration: a risk factor for HIV infection in rural Senegal
Article Abstract:
Seasonal migration may contribute to the spread of HIV infection in rural areas. A survey taken of 3,230 adults in a rural area of Senegal found 25 were HIV-2 positive and 2 were HIV-1 positive. Seasonal migration was the only factor significantly associated with being HIV positive. Every year, about 80% of the women between 15 and 24 years old and 82% of the men between 20 and 40 years old move for seasonal work to the main cities of Senegal or the Gambia. Sexual transmission of HIV in the rural area studied appears to occur in two steps: first, men become infected from women they have sexual intercourse with during seasonal migration and then they infect their wives or regular partners upon returning home. The high incidence of sexually transmitted diseases among the HIV-infected men supports the hypothesis that the men participate in high-risk sexual behaviors during migration.

Epidemiology of HIV infection in St. Petersburg, Russia
Article Abstract:
The overall incidence of HIV infection in St. Petersburg, Russia appears to be low, (0.002%) but among certain populations it is significantly higher. Of the 25 HIV-positive men, 18 are homosexual and 5 are bisexual. The overall rate of HIV infection among non-Soviets in St. Petersburg is 0.01%. Among students from Uganda and Rwanda, however, the rates are estimated to be 5.5% and 3.1% respectively. Since 1987, foreigners applying to enter the country have been pre-screened for HIV infection, and the incidence among recent entrants from Africa is lower. Of 11 HIV positive women, 10 reported having sexual contact with Africans. There is one known case of mother-to-infant transmission and one case of a child infected through the use of an infected needle, but otherwise sexual contact appears to be the main means of transmission.
