Widespread HIV counseling and testing linked to a community-based tuberculosis control program in a high-risk population.
The aim of the work reported here was to evaluate community-wide screening for HIV infection that was linked to a tuberculosis control program in a population at high risk for both infections. Between May 1990 and August 1992, adults in Cité Soleil, Haiti, were recruited by community health workers at their homes and in clinics for individual, clinic-based counseling and testing for HIV and tuberculosis. All of the screened subjects were offered post-test HIV counseling. ⋯ The high prevalence of HIV infection found in this screened population, as compared to other groups undergoing HIV screening in the same community, suggests that people at high risk for HIV infection selectively sought or accepted tuberculosis clinic screening. Also, many people with active tuberculosis were identified earlier in the course of their disease than they would have been in the absence of a screening program. Overall, the results indicate that community-based screening for HIV infection within a tuberculosis control program can result in effective targeting of screening for both infections.

Current laboratory techniques cannot distinguish the mode of vertical transmission (intrauterine, intrapartum, or postnatal) of human immunodeficiency virus type 1 (HIV-1) from mother to infant. The ability to transmit HIV-1 via breast feeding has been established in 24 case reports, primarily involving mothers who seroconvert after delivery. Whether breast-feeding adds a notable additional risk of HIV-1 infection to the risk from pregnancy is controversial. ⋯ Pasteurization and storage enhance the intrinsic, antiviral properties of human milk. Banked human milk is pasteurized to destroy the HIV-1 virus but retains properties that may be helpful to infants of HIV-1-positive mothers in developed countries where breast-feeding is not recommended. For infants in populations where the infant mortality rate is high, the risk of death associated with HIV infection acquired via breast milk is lower than the risk associated with not being breast-fed.

We recognize that many of the issues raised are not simple. Our proposal calls for the same thoughtful deliberation applied in other settings to be brought to bear on reproductive health care. Some have already tried alternative approaches. ⋯ In developing policy we should consider the impact on the legal and ethical rights and obligations of both patient and physician. For every course, we should evaluate both immediate and long-term efficacy, the consequences for the doctor-patient relationship, and the consequences for medical integrity. In the midst of the present regulatory and fiscal turmoil affecting health care, we urge physicians to be careful and deliberate in the policies they embrace and the actions they take.
