PURPOSE: To establish the prevalence of viral etiology in patients with community acquired pneumonia(CAP), and determine the most common viral pathogens causing CAP.

METHODS: This is a retrospective cohort study. Patients admitted to the University of Louisville Hospital with CAP over a year were included.

RESULTS: This study included 113 patients, of whom 52 (48%) were males. Thirty-three (29%) patients had a viral infection. The most common viral pathogen was influenza, which was detected in 16 (14%) patients. Co-infection with bacterial pathogens occurred in 10 (8.8%) patients, and co-infection with other viruses occurred in 11 (9.7%) patients. Four (3%) patients died in the hospital. The mean length of stay was 12.3 (SD = 6.9) days, and the mean time to clinical stability was 5.5 (SD = 3) days.

CONCLUSIONS: The prevalence of viral etiology in patients admitted with CAP is high. Co-infection with bacterial pathogens and other viruses is also common. Influenza remains the most common viral etiology in these patients.

CLINICAL IMPLICATIONS: This study will help identify the patient population at higher risk for CAP by knowing the risk factors. It will also identify the common viruses that cause CAP.and which viruses can cause severe CAP that needs to be admitted to the intensive care unit which can have prognostic value. It can also help guide the empiric antibiotic treatment by finding the common co-infecting bacteria.
