Is emphysema contagious?

Some lung diseases are contagious, so can emphysema be contagious?

Emphysema will gradually worsen with the development of fibrosis, and most patients will die of respiratory and circulatory failure. Not all respiratory diseases are contagious. Although emphysema is a respiratory disease, it is not contagious and will not be transmitted to others.

Emphysema refers to chronic respiratory diseases caused by over-inflation of lungs caused by various reasons. Although emphysema is not contagious, it is hereditary, and people with emphysema usually have some complications, such as spontaneous pneumothorax, that is, sudden chest pain and shortness of breath, which may also cause acute lung infection, chronic pulmonary heart disease and respiratory failure. Therefore, patients with emphysema should be actively treated.
