Tuberculosis can be transmitted through dishes, although it is relatively uncommon. Tuberculosis is mainly spread by droplet transmission, which is the emission of Mycobacterium tuberculosis into the air by coughing, sneezing, laughing, and talking loudly, etc. Transmission through other routes such as the digestive tract or skin is very rare. If you have tuberculosis in your home, it is important to regularly disinfect any eating utensils or household items that have been used by tuberculosis patients. Food utensils should be cooked at high temperatures, and household items such as bedding should be exposed to sunlight. Tuberculosis patients should not spit anywhere, but should spit into a spittoon or wrap it in paper and put it together to be burned or disinfected and then dumped. Patients with tuberculosis should live in a separate room by themselves, and the room should be ventilated 2-3 times a day for at least 30 minutes each time.
