Pneumonia is a common respiratory infection,[2] affecting approximately 450 million people a year and occurring in all parts of the world.[3] It is a major cause of death among all age groups, resulting in 1.4 million deaths in 2010 (7% of the world's yearly total) and 3.0 million deaths in 2016 (the 4th leading cause of death in the world).[3][4]
There are various causes of pneumonia including bacteria, viruses, and fungi.[5] Pneumonia can be acquired from different sources such as in hospitals, the community, or through use of ventilators.[6]
Pneumonia is a type of lower respiratory tract infection, and is also the most deadly communicable disease as of 2016.[4] Rates are greatest in children less than five and adults older than 75 years of age.[3] It occurs about five times more frequently in the developing world versus the developed world.[3] South Asia and Sub-Saharan Africa have the highest prevalence of pneumonia in the world.[7]
We can prevent and treat pneumonia through vaccines, proper treatments, and healthy practices.[8]
