Microaspiration of contaminated secretions can infect the lower airways and cause pneumonia. The progress of pneumonia is determined by the virulence of the organism; the amount of organism required to start an infection; and the body's immune response against the infection.
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).

Atypical bacteria causing pneumonia are Coxiella burnetii, Chlamydophila pneumoniae (), Mycoplasma pneumoniae (), and Legionella pneumophila.. The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact that these organisms have atypical or absent cell wall ...
Vaccines can dramatically reduce the risk of severe infection and death from COVID or respiratory viruses like pneumococcal pneumonia and flu, or prevent HPV infections and related cancers.
A local staffer with the UN's global health program works to raise awareness of the risks and outlook of pneumonia in children. World Pneumonia Day: Respiratory illness in children can lead to ...
The resulting lung inflammation is not an infection but can contribute to one, since the material aspirated may contain anaerobic bacteria or other unusual causes of pneumonia. Aspiration is a leading cause of death among hospital and nursing home patients, since they often cannot adequately protect their airways and may have otherwise impaired ...
