Seroepidemiologic Investigation of an Outbreak of Pandemic Influenza A H1N1 2009 Aboard a U.S. Navy Vessel - San Diego, 2009.

摘要

Retrospective serologic analysis in paired sera demonstrated that more than half of pH1N1 infections were asymptomatic, and thus the attack rate was higher than estimated by clinical illness alone. Enhanced infection control measures including pre-embarkation illness screening, improved self reporting of illness, isolation of ill and quarantine of exposed contacts, prompt antiviral chemoprophylaxis and treatment may be useful to control shipboard influenza outbreaks.
