Severe A(H1N1)-associated Pneumonia Sequential to Clamidophila pneumoniae Infection in Healthy Subject.

Background: Pandemic influenza virus has been implicated in serious lower airways illness and death in subjects both with and without underlying medical conditions . Predictive factors for severe disease in healthy individuals have not been identified. Case Report: Severe A(H1N1)-associated pneumonia occurring in a healthy subject without underlying medical conditions sequential to a Clamidophila pneumoniae infection, is reported. Conclusion: A potential synergistic mechanism by which other pathogens could interfere with the clinical course of A(H1N1) infection, is suggested.
