ALERT is a medical facility on the edge of Addis Ababa, specializing in Hansen's disease, also known as “leprosy”.

It was originally the All Africa Leprosy Rehabilitation and Training Center (hence the acronym), but the official name is now expanded to include tuberculosis: All Africa Leprosy, Tuberculosis and Rehabilitation Training Centre.

From the beginning, ALERT provided leprosy training for medical students from Addis Ababa University.

There is currently a 240-bed teaching hospital, which includes dermatology, ophthalmology, and surgery departments, also an orthopedic workshop, and a rehabilitation program.

A memorandum to found ALERT was signed Dec. 11, 1965 by representatives of the Ministry of Health, Addis Ababa University, the International Society for the Rehabilitation of the Disabled, The Leprosy Mission, and Dr. Eugene Kellersberger of the American Leprosy Mission, who had had the vision for establishing such a multifaceted center and had been the main promoter of the project.
