TB Facts for Health Care Workers
Tuberculosis - Yes! It's Still a Problem!
- The HIV epidemic
- Immigration of persons from areas with a high prevalence
- Transmission of TB in high-risk environments, such as
correctional facilities, homeless shelters, hospitals, and
- Deterioration of the TB public health care infrastructure
During the resurgence of TB, outbreaks of multidrug-resistant
TB occurred in hospitals and prisons, resulting in high death
rates and transmission to health care workers.
The 21,337 TB cases reported in 1996 represent
the fourth consecutive year of decline, suggesting the successful
use of new resources in different areas of the U.S. to better
detect and treat persons with active TB and latent infection.
- While the decrease in TB cases is encouraging, there are
several areas of concern which will require expanded efforts:
- TB cases continue to increase in many areas.
- Outbreaks of drug-resistant TB continue in many areas.
- An estimated 10 to 15 million persons in the U.S. are
infected with Mycobacterium tuberculosis. Without
intervention, about 10 percent of these persons will develop
TB disease at some point in life.
- Directly observed therapy is not available for many persons
with active TB who have difficulty completing a full course
of TB treatment.
- An increasing proportion of TB cases in the U.S. are among
individuals born in areas with a high prevalence of TB,
and international collaboration needs to be strengthened
to prevent and control TB in these persons.
