Zambia: cases and investigations
Unexpected infections in children
1991-93: In 1991-93, WHO’s Global Programme on AIDS arranged for hospitals to test children aged 6-59 months (1/2 to 5 years old) admitted to pediatric care and their mothers in 4 cities in Africa: Kigali, Rwanda; Dar es Salaam, Tanzania; Kampala, Uganda; and Lusaka, Zambia. Out of 5,593 child-mother pairs, 61 (1.1%) children were HIV-positive with HIV-negative mothers. Reports from this study do not give any breakdown by country. The authors conclude (incredibly!): “The risk of nosocomial and non-perinatally acquired HIV infection appears low among these populations.” This shows a double-standard for Africa; if 1% of inpatient Europeans had unexpected HIV infections, such a conclusion would be unacceptable.

Unexpected infections in adolescents and adults
1997-98: In a 1997-98 survey among young adults aged 15-24 years in Ndola city, 7.6% (8/106) of women who said they were virgins were HIV-positive vs 34.9% (119/341) of sexually active women. Among men who said they were virgins, 4.8% (3/63) were HIV-positive vs 10.4% (19/182) of sexually active men. The source that reports these data asserts that men and women “misreported their sexual activity.” Source: Buve A, Lagarde E, Carael M, et al.

2007: Among young adults aged 15-24 years, a random sample national survey in 2007 found that 3.4% of women who said they were virgins were HIV-positive compared to 8.5% of all young adult women. Among young adult men, 3.5% of those who said they were virgins were HIV-positice vs. 6.5% of all young adult men.
