Atypical Pneumonia

Atypical pneumonia (pronounced: əˈtɪpɪkəl nuːˈmoʊniə), also known as walking pneumonia, is a type of pneumonia not caused by one of the pathogens most commonly associated with the disease. Its clinical presentation contrasts to that of "typical" pneumonia.

Etymology

The term "atypical" refers to the pathogen's resistance to penicillin treatment, which is effective against the "typical" pneumonia pathogens. The term "walking" refers to the milder nature of this type of pneumonia, which often doesn't require bed rest or hospitalization.

Causes

Atypical pneumonia is caused by certain bacteria, including Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella pneumophila. Viruses and fungi can also cause it.

Symptoms

Symptoms of atypical pneumonia include fever, cough, chest pain, and shortness of breath. These symptoms are similar to those of typical pneumonia but are often milder.

Diagnosis

Diagnosis of atypical pneumonia is typically made based on the characteristic clinical features and may be confirmed with a chest x-ray or other imaging studies. Laboratory tests may also be used to identify the specific pathogen causing the infection.

Treatment

Treatment for atypical pneumonia includes antibiotics that are effective against the specific pathogen causing the infection. Rest and hydration are also important components of treatment.
