Arm Intervention/treatment
No Intervention: Passive Household Contact Evaluation
Passive case finding refers to the current National TB program of voluntary self-reporting of symptomatic patients to the health system for diagnosis of TB and initiation of effective chemotherapy
Experimental: Active Household Contact Evaluation
The intervention program includes households visits of all newly diagnosed TB cases enrolled in TB treatment within a DISA NTP clinic in SJL district. During the home visit health staff will evaluate all household contacts for symptoms of active TB. Any person reporting cough for >14 days will be asked to provide a spot sputum for microscopy and referred to the clinic for chest x-ray and clinical evaluation. All household contacts ≤19 years will be referred to the clinic for chest x-ray, pediatric clinical evaluation and initiation of treatment for active or latent TB as required. Counseling including TB infection control practices and importance of diagnosis and treatment completion for TB cases will be provided to household members.
Other: Active Household Contact Evaluation
Active evaluation of TB household contacts will be introducted as a new intervention in the district. The intervention will be undertaken by routine public health staff under routine conditions, however the assignment, training, monitoring and supervision of this intervention will occur in a stepped wedge roll out.

Primary Outcome Measures :
  1. Active Tuberculosis [ Time Frame: 6 months ]
    Evaluation of active Tuberculosis in exposed household contacts of TB patients enrolled in treatment
