Hesperian Health Guides develops and distributes health materials that provide knowledge for action, and inspire action for health. Our guides are designed in partnership with and for community health workers and others in poor and marginalized communities around the world to prevent and cure disease, and to challenge the social injustices that cause poor health. Beginning with the development of the classic Where There Is No Doctor in the mountains of Mexico in the early 1970s, we have collaborated with partners to produce health materials now available in over 80 languages. Hesperian’s expanding digital resource center is open to people around the world to help them customize, translate, and download materials.
