Some smarties have created something called JustMilk, it’s a nipple shield that can be modified to include a microbicide to kill the HIV virus and stop mother-to-child transmission. (Nipple shields are for moms who have trouble breast-feeding.) About 400,000 children contract HIV worldwide each year, and nearly all acquire the virus from their mothers. And the risk of transmission is significantly increased through breast feeding. However, the only way to lower the risk is to formula feed, which is usually unsafe, expensive and impractical, especially in developing countries, where formula-fed babies then face a higher risk of malnutrition, diarrhea and other infections. This shield, would allow women to breast-feed without passing along the virus. Click here for more.
