Emphysema is not contagious, but if there is a combination of viruses spread through the digestive tract you will need to sanitize your dishes.
Emphysema is a disease of the lungs caused mainly by long-term exposure to airborne irritants such as tobacco, chemical fumes and dusts, and air pollution, and partly by congenital emphysema due to antitrypsin deficiency. This shows that emphysema is not an infectious disease.
However, if the patient has a combination of viruses transmitted through the digestive tract, sharing dishes may cause infection, and this is when disinfection is needed.
It is important to note that emphysema should be checked and treated in a timely manner, so as not to affect the condition, and to maintain a healthy diet and work routine to create a good living environment.
