Pneumonia is an infection which causes inflammations in the air sacs, medically termed as “alveoli,” in one or both lungs. When you have pneumonia, these alveoli get filled with fluid or pus thus making it hard. As a result, the lung’s ability to transfer oxygen to the blood gradually reduces, finally leading to death.
