People may become infected with pneumonia in a hospital; this is defined as pneumonia not present at the time of admission (symptoms must start at least 48 hours after admission). [ 85 ] [ 84 ] It is likely to involve hospital-acquired infections , with higher risk of multidrug-resistant pathogens.
Walking pneumonia, a less severe form of pneumonia, is primarily caused by mycoplasma pneumoniae. The bacteria can damage the lining of the respiratory tract, including the throat, windpipe and lungs.
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).

Influenza, Human orthopneumovirus (RSV), and human coronaviruses are more prevalent in the winter. Human bocavirus and Human metapneumovirus occur year-round, rhinoviruses (which cause the common cold) occur mostly in the spring and fall, and human parainfluenza viruses have variable peaks depending on the specific strain.
People with a compromised immune system, such as those living with HIV, are also at higher risk of pneumococcal disease. [5] In HIV patients with access to treatment, the risk of invasive pneumoccal disease is 0.2–1% per year and has a fatality rate of 8%. [5] There is an association between pneumococcal pneumonia and influenza. [6]
In fact, the proportion of people leaving emergency rooms with a diagnosis of walking pneumonia has increased over the last six months. Naturally, people have questions and concerns.
