Pneumonia is an infective disease of the lungs where the alveoli are primarily involved. The most common pathogens responsible for pneumonia are bacteria like Streptococcus pneumoniae and Haemophilusinfluenzae. The alveoli get filled up with fluid leading to difficulties in respiration. Symptoms of pneumonia include fever, chills, cough and headache. In severe cases cyanosis may occur i.e. bluish colouration of the lips and finger nails. It can spread through inhalation of droplets or aerosols from an infected person.
