Tanzania: cases and investigations
Unexpected infections in children:
1988: Tests of malnourished children admitted to Muhimbili Medical Centre, Dar es Salaam, during 1988 identified 51 HIV positive children aged 3 to 88 months. Seven of 47 (14%) tested mothers were HIV-negative; all 7 children with unexpected infections had received blood transfusions. Source: Mgone CS, Mhalu FS, Shao JF, et al.

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. The studies tested 5,593 child-mother pairs, of which 61 (1.1% of 5,593) 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 HIV infections in adolescents and adults: In a survey of young adults aged 15-24 years in Moshi rural district in 1995, 5.6% (8/141) of young men who did not report any lifetime sexual activity were HIV-positive vs. 4.8% (16/335) of young men who reported 1 or more lifetime sex partners. Among young women who did not report any lifetime sexual activity, 3.7% (6/163) were HIV-positive vs. 12.4% (45/364) of those who reported 1 or more lifetime partners.
