According to the medical journal The Lancet
, approximately 20 million low birth-weight and premature babies are born around the world every year. Of those, about 4 million die within four weeks. Many of those deaths take place because the infants can’t maintain a high enough body temperature on their own, and succumb to hypothermia. Incubators are designed to address this problem, but many hospitals in developing nations can’t afford them, nor can they provide the uninterrupted power supply that the machines require. The San Francisco non-profit group Embrace, however, is developing what could be an effective and affordable alternative – the Infant Warmer.
