For tuberculosis, you can visit the Department of Infectious Diseases. Infectious diseases or respiratory medicine are suitable options, and if a hospital doesn't have these specialized departments, you can consider visiting the Center for Disease Control. In smaller hospitals, below the secondary level, where such specific departments may not be available, you might also consider seeing the Department of General Internal Medicine. General Internal Medicine or typical internal medicine departments can also handle this. However, our first recommendation would still be the Respiratory Medicine Department. Some hospitals combine Infectious Diseases with other related departments, making them the preferred choice for tuberculosis patients as these departments likely have the most experience in treating such diseases.
