What Is Atypical Pneumonia?
2. What Are Common Causes of Atypical Pneumonia?
There are four main infectious bacteria that cause walking pneumonia. One is Chlamydophila pneumoniae, which is more common in young adults and school-aged children. Mycoplasma pneumoniae is more typical in people under the age of 40. In addition to pneumonia symptoms, this bacterium also causes headaches, earaches and a sore throat.
Legionella pneumophila is a bacterium that causes more severe symptoms. Also known as Legionnaire’s disease, it is more common in people with weakened immune systems, such as those who smoke and older adults. A less common cause, Chlamydophila psittaci, comes from infected poultry and pet birds.
