Variant asthma is not contagious. Variant asthma is a specific type of asthma that is a chronic inflammatory condition but is essentially an immune response caused by both genetic and environmental factors.

However, the pathogenesis of asthma is dominated by airway immune-inflammatory and neuromodulatory mechanisms. Although there will be inflammation, but the inflammation is due to the body’s autoimmunity, not due to foreign pathogenic microorganisms directly caused by infectious inflammation, that is to say, at this time it is a kind of aseptic inflammation. Therefore, there is no possibility of infection.
