Women and girls do not live in isolation. They are members of communities, part of a social fabric. Improving the health and well-being of women and girls requires that we address not only their immediate health needs, but the broader health challenges faced by their communities. There is a symbiotic relationship: healthy mothers are needed for healthy families and healthy communities, and vice versa. As microfinance programs provide paths out of poverty, women are able to provide for their families, and basic health education can prevent unnecessary illness and death. Access to safe drinking water and sanitation not only prevent a wide range of illnesses, but they provide dignity, a path to prosperity, and protection from abuse and violence.
