i. The CDC's nationwide goals serve as a broad context for looking at San Francisco's experience in dealing with the re-emergence of TB. The CDC's targeted case rate is a decrease from 9.3 per 100,000 in 1987 to 3.5 per 100,000 in 2000, to elimination (less than 1 per 100,000) by 2010.
Three broad steps are defined as integral in meeting this goal:
2. Development and evaluation of new technologies for treatment, diagnosis, and prevention
3. Rapid assessment and transfer of new developed technologies into clinical and public health practice
ii. Organizations involved in the TB effort in San Francisco include the following:
ii. Research now focuses on using molecular epidemiology and traditional epidemiologic techniques to identify strains of TB and thus the common source of infection responsible for TB outbreaks. Research is needed to discover more effective and less toxic drugs, as well as alternatives to daily therapy regimens. Research is needed to develop tests which will identify those who harbor living tubercle bacilli (i.e. are infected) but have not yet developed the disease and to develop tests for other factors affecting the probability of an infection leading to disease. Research is also needed into more effective methods to prevent transmission of infection and to develop cheaper, more effective and shorter drug regimens.
iv. The Francis J. Curry National Tuberculosis Center has developed the elements of a model surveillance system. The Stanford Center for Tuberculosis Research, through their epidemiologic studies, has pursued the hypothesis that the clinical and epidemiologic manifestations of TB may be specifically associated with the transmissibility and tissue tropism properties of particular strains of TB bacteria. Some of their researchers have concluded that nearly 1/3 of new TB cases in 1991 and 1992 resulted from recent infection as opposed to reactivation of latent infection acquired earlier in life. This fact, along with the increasing incidence of MDR-resistant TB suggests that more aggressive control measures are necessary. Surveillance is focused on risk groups, such as newly arrived immigrants and refugees, hospitals, homeless shelters, jails, prisons, residential facilities, nursing homes, mental institutions, substance-abuse treatment centers, dialysis units, home health-care agencies, and communal living situations (NTC, Stanford).
v. The
Francis J. Curry National Tuberculosis Center provides education to 750 medical and social service providers annually. Eleven core courses include "Effective Tuberculosis Interviews: Targeting Special Populations", "Preventing Occupational Transmission of Tuberculosis", "Preventing Tuberculosis in Acute Care Hospitals", "Radiology Seminar", "Tuberculosis and the Law", "Tuberculosis Case Management", Tuberculosis Intensive", "Tuberculosis Overview", Tuberculosis Program Managers Course", "Tuberculosis Update", and "Use of Surveillance Data to Guide and Evaluate Tuberculosis Control Programs". The California State Department of Health Services, Tuberculosis Control Branch funds an on-site training program to improve the effectiveness of TB control programs (NTC).
