Refrigerators used by TB patients can be used by healthy people after sterilization.
The main way of spreading tuberculosis is droplet transmission. When a patient coughs, talks or laughs, Mycobacterium tuberculosis will spread from the respiratory tract into the air and stay there for a few hours, which may be infected if others inhale it.
When a healthy person uses a refrigerator that has been used by a TB patient, it should be disinfected, such as irradiation with ultraviolet disinfection lamps, 75% medical alcohol, etc., all of which can effectively kill Mycobacterium tuberculosis.
Not all patients infected with Mycobacterium tuberculosis are contagious to others, for Mycobacterium tuberculosis latent infection, inactive tuberculosis patients are generally not contagious, in the active stage of tuberculosis patients are more contagious.
If you are diagnosed with TB, it is recommended that you undergo standardized treatment as soon as possible to minimize the adverse effects of the disease.
