Pneumonia and asthma are two different health conditions with similar symptoms and circumstances. Pneumonia is an illness of the lung tissue, which entails the air sacs within them, which are called alveoli. With pneumonia, there is fluid and cell debris in these air-filled sacs. Asthma, on the other hand, creates a sensitivity in the lungs and reaction to the alveoli.
It is an allergic response that leads to severe narrowing of the air passages that result in the abrupt cutoff of oxygen supply to the body. The common causes of pneumonia are viruses, bacteria, and fungi. Asthma, on the other hand, maybe due to allergies, dust, animal hair, dander or pollen, and cold weather.
