Transmission of TB is person to person through inhalation of droplet nuclei in the air. The majority of patients infected with M. tuberculosis develop latent tuberculosis infection and do not develop active, symptomatic, disease. Approximately 10% of patients develop active disease if not treated with isoniazid. Risk of active disease is highest in the first 2 years after infection.
