Tuberculosis patients who are contagious are not allowed to continue to work, and must be immediately isolated for treatment, and can continue to work after treatment that is not contagious. If the diagnosis of tuberculosis is confirmed, and is active, infectious, can not continue to work. Tuberculosis is a common infectious disease, mainly through the respiratory tract, contact, etc. If you continue to work after diagnosed with tuberculosis, it is likely to be infected to the surrounding coworkers, resulting in the widespread spread of the disease. It is therefore important to seek immediate medical attention, usually in a hospital for infectious diseases, for isolation treatment. Strictly speaking, tuberculosis requires a full course of anti-tuberculosis treatment of about 6 to 9 months before it can be cured. The purpose of isolation is to avoid further spread of the disease and to minimize the impact of the disease on the health and lives of colleagues and family members. After treatment, three consecutive sputum smears are negative for bacilli, indicating that the patient is no longer contagious and can return to work after being evaluated by a physician.
