The benefits of breast milk have been well delineated, and breastfeeding should be encouraged whenever possible. However, the potential transmission of HIV-1, HTLV-1, and possibly HTLV-II warrant the recommendation that women in industrialized countries who are infected with these viruses not breastfeed their infants. These recommendations reflect what is currently known about the risks of viral transmission through breastfeeding; ongoing and future studies may provide additional data, enabling a better definition of the precise risks and factors associated with the transmission of viruses through breastfeeding.

IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
