Tuberculosis is a preventable disease and the most important measure to prevent its transmission is to provide adequate ventilation, in the community.
Even the hospitals and clinics try to take precautions such as using ultraviolet light to sterilize the air, special filters to keep away the bacteria and special respirators and masks to prevent
the other people from being infected. In hospitals, especially, people infected with TB are kept in special isolated rooms with controlled airflow and ventilation so that they do not spread
the bacteria
