Abstract
It is very important to prevent secondary infections of tuberculosis. If a case of tuberculosis infection is found in a hospital, we need to expend much time and labor on a follow-up survey. We experienced two cases of laryngeal tuberculosis. In the first case, we found germ discharge of tuberculosis in the hospital. As a result, we needed to follow up on potential secondary infections for patients who were in the same room as the tuberculosis patient. With the second case, we investigated the germ discharge in the outpatient department. We studied the prevention of secondary infections of laryngeal tuberculosis.
