Tuberculosis (TB) is endemic in India, and diagnosis is frequently delayed. Unsuspected TB cases contribute to TB transmission because they are not being treated and may go unsuspected for days or weeks, and may visit multiple health-care facilities. Unless TB is considered, available diagnostic tests may not be used, proper treatment might not be initiated and proper TB infection control measures might not be in place. Therefore, TB Infection Control (TB-IC) measures should be implemented effectively to reduce transmission.
