Global Surveillance of Communicable Diseases

摘要

A recent report of A/Sydney/05/97-like (H3N2) influenza on a cruise ship from New York to Montreal demonstrates the ease with which communicable diseases can be transferred across international borders (1). In this outbreak 2.7% of passengers and 0.5% of crew had acute febrile respiratory illness during or after the cruise and introduced this antigenic variant of influenza A into both Canada and the United States.
