The epidemiology of tuberculosis in the U.S. Air Force, 1987

In preparation for a major revision of the Air Force tuberculosis (TB) prevention and control program, we reviewed tuberculosis cases treated at Air Force hospitals and the U.S. Air Force tuberculin skin testing program for 1987. The highest rates of active TB cases and infection were observed in the Pacific overseas region. Active tuberculosis cases occurred most frequently in white male retirees and in Asian dependent females. Nineteen cases (9% of total TB cases) occurred in children under the age of 5. Only 46-60% of individuals with a positive Purified Protein Derivative-Tuberculin were placed on isoniazid (INH) chemoprophylaxis. Flying status personnel were less likely to have either active disease or TB infection than non-flying active duty members. Based upon these findings, Air Force tuberculosis prevention and control program efforts should de-emphasize screening of low risk active duty populations and stress timely reporting and case finding, compliance with therapy, and initiation of INH chemoprophylaxis in accordance with existing guidelines. Young children who are contacts of active TB cases should receive special emphasis.
