Local Bah ' communities, however, are part of a network that is able to mobilize resources from outside their local area. For example, in the Philippines, as a result of grass roots initiative, a Bah ' medical team is now providing regular services to the remote Mangyan area of Mindoro, a tribal region never before served by physicians. Undaunted by the rugged terrain, Bah ' s from several communities in the area supported the team's efforts. They created a relay race to carry an ice chest filled with live vaccine 41 kilometers into the interior. As a result, hundreds of Mangyan children were immunized.
Malnutrition is one of the major public health problems in developing countries.
It stems from poverty and ignorance. The family must be helped to learn nutrition habits and must be served by better basic health care. The Bah ' community health care workers provide basic nutrition education as a part of their .primary health care services. Promoting breast feeding, teaching mothers to make appropriate weaning food utilizing locally available food, and training them to make oral rehydration solutions, form part of the basic nutrition education that is being carried out by the Bah ' community health care workers. Malnutrition is often both a result and a cause of social and economic under-development.
