Abstract
The postnatal transmission of human immunodeficiency virus (HIV) from mothers to children occurs through breastfeeding. Although heat treatment of expressed breast milk is a promising approach to make breastfeeding safer, it is still not popular, mainly because the recommended procedures are difficult to follow, or time-consuming, or because mothers do not know which temperature is sufficient to inactivate HIV without destroying the nutritional elements of milk. To overcome these drawbacks, a simple and rapid method of heat treatment that a mother could perform with regular household materials applying her day-to-day art of cooking was examined. This structured experiment has demonstrated that both cell-free and cell-associated HIV type 1 (HIV-1) in expressed breast milk could be inactivated once the temperature of milk reached 65°C. Furthermore, a heating method as simple as heating the milk in a pan over a stove to 65°C inhibited HIV-1 transmission retaining milk's nutritional key elements, for example, total protein, IgG, IgA, and vitamin B(12) . This study has highlighted a simple, handy, and cost-effective method of heat treatment of expressed breast milk that mothers infected with HIV could apply easily and with more confidence.
