Tuberculosis Prevention

Tuberculosis prevention generally focuses on preventive treatment in people who have latent tuberculosis, precautions at hospitals and clinics, and reducing exposure when a person is infectious. Tuberculosis is largely a preventable disease, so it is important to follow the general guidelines of tuberculosis prevention in order to keep yourself, as well as family members, healthy and safe.

 

An Overview of Tuberculosis Prevention

Generally, tuberculosis (TB) is a preventable disease. Tuberculosis prevention focuses on:
 
  • Preventive treatment in people who have a positive TB test without symptoms of tuberculosis (latent tuberculosis)
  • Precautions at hospitals and clinics
  • BCG vaccine
  • Reducing exposures when a person is infectious.
     

Preventive Treatment

In the United States, healthcare providers try to identify people infected with tuberculosis as early as possible, before they have developed active tuberculosis. These people can then be treated and cured before they become contagious.
 
Anyone who has been exposed to a person with TB should be tested for latent tuberculosis (see TB Test). TB is especially dangerous for children and people with HIV infection. If infected with TB bacteria, these people need medicine right away to keep from developing active TB.
 

Hospitals and Clinic Precautions

Hospitals and clinics take precautions to prevent tuberculosis transmission, which include using ultraviolet light to sterilize the air, special filters, and special respirators and masks. In hospitals, people with TB are isolated in special rooms with controlled ventilation and airflow until they can no longer spread tuberculosis.
