Women from industrialized societies who do not breastfeed have a transmission risk of 15 to 20% , however, on those who breastfeed it is of 30 to 35%. In those developing countries with a high mortality rate BF is mandatory, since bottle feeding represents an actual threat to infant’s life, still more dramatic than on non-infected children. By heating breast milk at 56ºC for 30 minutes, or, pasteurizing it (62,5ºC 30 minutes) HIV is inactivated.
