Tuberculosis, or TB, is a hugely contagious disease. Infections can spread among individuals through droplets or sneezing from an untreated patient. This infectious disease can affect any body part, but it primarily affects the lungs. It may also affect the nervous system, bones, abdomen, genital, urinary systems and lymph nodes. In a country like India, tuberculosis infects 90% of the population. Symptoms include fever or cough for over two weeks, weight loss and loss of appetite. Recognising the differences between tuberculosis infection and disease is essential so that appropriate treatments may be offered to patients. Dr. Sangeeta Bhattacharya Samadar, a pulmonologist, talks extensively about TB and its causes and implications.
