Here are some things to keep in mind when you are with a patient with tuberculosis For patients with open tuberculosis, contact with them should be kept to a minimum because they are highly contagious. This is because even with appropriate protection, transmission can occur because they are highly contagious. Only after 1-2 months of anti-tuberculosis treatment, when the infectiousness of the patient decreases significantly, can appropriate contact with the patient be made. Healthy people should pay attention to minimizing close contact with patients for a long time, and if they are in the same environment with patients, they should pay attention to keeping the air in the room unobstructed and hygienic. Patients should cover their mouth and nose when coughing, and try to spit out sputum in a closed container and destroy it accordingly, and do not spit anywhere. Maintain hand hygiene and wear a mask for protection if necessary. When eating with patients, separate dishes from each other. Only through the above measures can we avoid infection.
