Conclusion
Dr. S.K. Arora states that the combination of TB and diabetes is a double threat, but it can be controlled with timely screening and treatment. According to him, given the increasing syndemic relationship between Tuberculosis (TB) and Diabetes Mellitus (DM) in India, it is essential to establish and strengthen effective collaboration mechanisms for the control of both diseases. Integration between India’s National Tuberculosis Elimination Program (NTEP) and non-communicable disease (NCD) programs, particularly through NPCDCS (now for NCD), is essential.
