Respuesta :

Answer:

A

Explanation:

  • Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis.
  • It is spread via air when affected people cough, sneeze, spit or speak.
  • It mostly affects the lungs, thus, damaging the respiratory system. Affected people have difficulty breathing, produce bloody mucus and have a chronic cough.
  • Antibiotic treatment is used for treating it but many people have developed resistance to the antibiotic treatment, giving rise to a new condition called Multi Drug Resistant Tuberculosis (MDR-TB).
