Hesperian's classic manual, Where There Is No Doctor, is perhaps the most widely-used health care manual in the world.

Useful for health workers, clinicians, and others involved in primary health care delivery and health promotion programs, with millions of copies in print in more than 75 languages, the manual provides practical, easily understood information on how to diagnose, treat, and prevent common diseases. Special attention is focused on mutrition, infection and disease prevention, and diagnostic techniques as primary ways to prevent and treat health problems.

This 2007 reprint includes new material on preventing the transmission of blood-borne diseases, how HIV/AIDS is reflected in many health issues, and basic Antiretroviral treatment information, as well as updated information on children and aspirin, stomach ulcers, hepatitis, and malaria treatments.
