<s>[INST] What is TB Infection? [/INST] If people breathe in the TB bacteria and become infected, in most cases the body is able to
fight the bacteria to stop them growing. In some people the bacteria can remain asleep in
the body and become active later. Most people who are infected with TB never develop TB
disease. A tuberculin skin test is the preferred test to show if a person has been infected by
TB bacteria. Source: SA Health. Link: https://www.sahealth.sa.gov.au/wps/wcm/connect/1f8da955-b6d4-4f60-9e1a-f90fe8ac238b/Tuberculosis+FAQ+factsheet+SATBS+20181031.pdf?MOD=AJPERES&amp;CACHEID=ROOTWORKSPACE-1f8da955-b6d4-4f60-9e1a-f90fe8ac238b-osGVUZH. Field: Lung Disease. Disease: Tuberculosis </s>
