If a husband is found to have tuberculosis, his wife may also have tuberculosis. Open tuberculosis means that patients with tuberculosis excrete a large number of Mycobacterium tuberculosis bacteria, and their sputum is discharged into the environment, which can lead to tuberculosis infection through the respiratory tract in the surrounding people. Therefore, if a husband is found to have tuberculosis and is infectious, his wife is advised to go to a regular hospital for tuberculosis-related examination and use appropriate interruption or treatment according to the situation. If family members are found to have TB, they need to take protective measures as follows: 1. wear a good mask and try to disinfect and share dishes when the infectious period is stronger; 2. pay attention not to spit anywhere, and their spit is strictly disposed of to avoid its transmission to family members or healthy people in the surrounding area.
