Community-Acquired Pneumonia

Community-acquired pneumonia is an important cause of morbidity and mortality. It can be caused by bacteria, viruses, or fungi. Community-acquired pneumonia can be prevented through vaccination with pneumococcal, influenza, and COVID-19 vaccines. Diagnosis requires suggestive history and physical findings in conjunction with radiographic evidence of infiltrates. Laboratory testing can help guide therapy. Important issues in treatment include choosing the correct treatment venue, timely initiation of the appropriate antibiotic or antiviral, deescalation after negative culture results, switching to oral therapy, and short treatment duration.
