The most important thing a person can do to prevent the spread of MDR-TB is to take all their medications exactly as prescribed by their health-care provider. No doses should be missed and treatment should never be stopped early. Patients should tell their health-care provider if they are having trouble taking the medications. If patients plan to travel, they should talk to their health-care providers and make sure they have enough medicine to last while away. Health-care providers can help prevent MDR-TB by quickly diagnosing cases, following recommended treatment guidelines, monitoring patients’ response to treatment, and making sure therapy is completed. Another way to prevent getting MDR-TB is to avoid exposure to known MDR-TB patients in closed or crowded places such as hospitals, prisons, or homeless shelters. If you work in hospitals or healthcare settings where TB patients are likely to be seen, you should consult infection control or occupational health experts. Ask about administrative and environmental procedures for preventing exposure to TB. Once those procedures are implemented, additional measures could include using personal respiratory protective equipment.
