World Pneumonia Day is a global event observed every year on 12 November to spread awareness and educate people to combat Pneumonia disease, which is a world’s biggest infectious killer of adults and children, responsible for the majority of death of children below five around the world.

• Pneumonia is an inflammatory respiratory disorder caused due to bacteria, viruses or fungal infections which impair the air sacs of the lungs, called "Alveoli". It results in the accumulation of fluid or pus in the air sacs, making breathing difficult. It is a contagious disease and could be fatal for the person with weaker immunity, especially in the children's and elderly people.
• World Pneumonia Day was first observed on 12 November 2009, under the "Stop Pneumonia" initiatives by Global Coalition Against Child Pneumonia, a coalition of various institutions all together to fight the child mortality due to the respiratory infection.
