Answer

Answer

Rapid cavitation is not a typical feature of CAP.

Community-acquired methicillin-resistant S aureus (CA-MRSA) CAP presents as a fulminant CAP with rapid cavitation and necrotizing pneumonia caused by CA-MRSA (SCC mec IV) with the Panton-Valentine leucocidin (PVL) gene. CA-MRSA CAP sometimes occurs after influenza but may also develop independent of influenza, even in young healthy hosts.
