Abstract

Entry screening for influenza A(H1N1)pdm09 at Auckland International Airport, New Zealand, detected 4 cases, which were later confirmed, among 456,518 passengers arriving April 27–June 22, 2009. On the basis of national influenza surveillance data, which suggest that ≈69 infected travelers passed through the airport, sensitivity for screening was only 5.8%.
The virus that caused the 2009 influenza pandemic, hereafter referred to as influenza A(H1N1)pdm09, is mainly spread internationally by air travel (1). To prevent or delay such spread, during the pandemic many countries initiated screening of air travelers arriving at airports, even though these measures have not been recommended by the World Health Organization (2). On April 25, 2009, New Zealand was one of the first countries outside the Americas to confirm influenza A(H1N1)pdm09 in arriving airline passengers (3). During April 27–June 22, 2009, at the direction of the Ministry of Health, the Auckland Regional Public Health Service began a screening program at Auckland International Airport.
