Entry screening for influenza A(H1N1)pdm[09] at Auckland International Airport, New Zealand, detected 4 cases, which were later confirmed, among 456,518 passengers arriving April 27–June 22, 2009
All flights notified New Zealand of the health of passengers and crew on board before landing; if indicated, the aircraft was met by public health officials who triaged these travelers
We estimated the number of infected travelers screened as the total number of confirmed cases in New Zealand during this period, multiplied by the proportion of overseas-acquired cases, and the proportion of international travelers arriving at the airport
