In case of open pulmonary tuberculosis, contact with TB patients should be reduced as much as possible during the infectious period, and if contact is necessary, a mask should be worn, the room should be ventilated, the patient should avoid talking loudly and coughing, cover the nose and mouth when coughing, and do not spit anywhere. Be careful not to have too close contact with them. If you eat in contact with a TB patient, be careful to separate and disinfect the dishes and pay attention to hand hygiene. In addition, if a family member suffers from tuberculosis, he or she should be isolated from the room as much as possible, be instructed to take oral anti-tuberculosis drugs regularly, have the patient’s sputum stored and disinfected in an airtight place, and pay attention to maintaining good living habits, nutritious diet, and strengthening their resistance.
