=== Tuberculosis ===
[[Tuberculosis]] (TB) is an [[infectious disease]] usually caused by the bacterium ''[[Mycobacterium tuberculosis]]'' (MTB). Tuberculosis generally affects the [[lung]]s, but can also affect other parts of the body.<ref>{{Cite web|url=https://www.who.int/en/news-room/fact-sheets/detail/tuberculosis|title=Tuberculosis (TB)|website=World Health Organization|language=en-US|access-date=2018-11-12}}</ref> Active or symptomatic tuberculosis is spread from person to person through the air through bacterium spores that are released into the air following a cough or sneeze. Some individuals may be infected with the tuberculosis mycobacterium but never display symptoms.<ref name=":5">{{Cite web|url=https://www.who.int/tb/areas-of-work/preventive-care/ltbi_faqs/en/.|title=Latent tuberculosis infection (LTBI)|website=World Health Organization|language=en-GB|access-date=2018-11-12}}</ref> Called [[latent tuberculosis]], these cases, while uncontagious, are particularly problematic from a public health perspective, since approximately 10% of those diagnosed with latent TB will go on to develop an active (and contagious) case.<ref name=":5" />
