abstract：:Several factors appear to affect vertical HIV-1 transmission, dependent mainly on characteristics of the mother (extent of immunodeficiency, co-infections, risk behaviour, nutritional status, immune response, genetical make-up), but also of the virus (phenotype, tropism) and, possibly, of the child (genetical make-up)...

This approach reduces but rarely, if ever, eliminates transmission. Indeed, snail infection rates may be little altered by such chemotherapy. Rei...
