Title: HIV Infection and Breastfeeding: Interventions for Maternal and Infant Health
Brief Summary: This is a comparative clinical trial among HIV-infected women and their infants to determine:

1. the benefit of nutritional supplementation given to women during breastfeeding
2. the benefit and safety of antiretroviral (ARV) medications given either to infants or to their mothers to prevent HIV transmission during breastfeeding
3. the feasibility of exclusive breastfeeding followed by early, rapid breastfeeding cessation

* Hemoglobin \>= 7.5 gm/dl within 4 weeks prior to study entry
* Serum glutamic pyruvic transaminase (SGPT) \< 5 times upper limit of normal within 4 weeks prior to study entry
* Serum creatinine \< 1.5 mg/dl within 4 weeks prior to study entry
* Consent form signed by the mother and, when possible, by the father, prior to the onset of labor
B: Inclusion Criteria for Mothers:

* HIV-infected
* At least at 26th week of pregnancy (treatment group) or 18th week of pregnancy (observational group) but not beyond the 34th week of pregnancy
* Able to complete study visits until at least 6 months postpartum
* Citizen of Botswana

Exclusion Criteria for Mothers:

* Taken ARVs for more than 1 week, other than ZDV, during current or prior pregnancy. Women who have received single-dose NVP in a prior pregnancy are not excluded.

Inclusion Criteria for Mothers:

* 18 years of age or older

* In third trimester of pregnancy, or at most 3 days post-delivery
* If baby is not yet born, planning to deliver at a facility where the study is being conducted
* Plan to breastfeed

Exclusion Criteria for Mothers:

Inclusion Criteria for Infants:

* Born to an HIV infected mother who is eligible for the study
* Weighed at least 2000 grams (4.4 lbs) at birth
* Blood sample obtained from the infant for HIV-1 DNA PCR, CBC with differential, and ALT
* Infants in a multiple birth are eligible only if both/all infants are eligible for the study and assigned to the same study group
* Able to breastfeed (e.g., mother and infant alive with no condition apparent that would prevent breastfeeding)

Exclusion Criteria for Infants:

* HIV DNA PCR positive at birth
* ALT of Grade 2 or higher at birth
* Hemoglobin, absolute neutrophil count, or platelet count of Grade 3 or higher at birth
* Skin rash of Grade 2B (urticaria), Grade 3, or above
* Confirmed or suspected clinical hepatitis

D: Inclusion Criteria:

Recruitment and primary eligibility criteria:

* Age \> 14 years.

* Evidence of HIV infection, as documented by 2 positive ELISA antibody tests; or 1 positive ELISA, and 1 Western Blot; or 2 separate concurrent rapid tests.
* Currently pregnant (with a single or multiple fetuses).
* Gestation \< 30 weeks at referral from 'Call to Action' Program
* No serious current complications of pregnancy.
* Intention to breastfeed.

* Mother's CD4 count \> 250 cells/uL determined in the antenatal clinic.
* Mother's ALT \< 2.5 x ULN (upper limit of normal) determined in the antenatal clinic

Secondary eligibility criteria and treatment assignment:

* Mother who delivers outside of the institution at which the study is based must present with her infant to the study site within 36 hours of delivery.
* Mother accepts nevirapine and zidovudine+lamivudine 7-day regimen for herself and her infant.
