Abstract :
Tuberculosis (TB) contacts are people who have close contact with patients with infectious TB. TB contacts should be investigated systematically and actively for TB infection and disease. Such interventions are called ‘tuberculosis contact investigations’. They contribute to early identification of active TB, thus decreasing its severity and reducing transmission of Mycobacterium tuberculosis to others, and identification of latent TB infection (LTBI), to allow preventive measures. The present study was undertaken to study epidemiological,socio-economic ,clinical factors in contact children of sputum positive cases. During study ,investigations were also carried out to differentiate stages of tubercular infection ,latency and disease
