Bacteria likeStreptococcus pneumoniae andHaemophilus influenzae are responsible for the disease pneumonia in humans, which infects the alveoli (air-filled sacs) of the lungs. As a result of the infection, the alveoli get filled with fluid leading to severe problems in respiration. The symptoms of pneumonia include fever, chills, cough and headache. In severe cases, the lips and fingernails may turn grey to bluish in colour. A healthy person acquires the infection by inhaling the droplets/aerosols released by an infected person or even by sharing utensils with an infected person.
