A novel H1N1 flu virus has infected humans in the United States and Mexico. This novel H1N1 flu virus is contagious and is spreading from human to human. However, at this time, it is not known how easily the virus spreads between people. Some infected individuals are known to have traveled on international and domestic flights while infectious.

Flight and cabin crew sometimes encounter ill passengers while performing their duties. When an ill passenger is identified, flight and cabin crew are required to report passengers who meet certain illness criteria.

Interim Recommendations

During the novel H1N1 flu outbreak, extra vigilance is required to identify and report passengers with respiratory symptoms or fever. Any passenger who appears ill, or who reports not feeling well, should be observed or queried for the following signs or symptoms:

• Feeling feverish or temperature greater than 100° F (37.8° C) if measured. For children, feeling warm by parent’s report.
• Sore throat
• Cough
• Stuffy or runny nose

Any passengers observed to have or who report having two or more of these symptoms should be reported immediately to the Airport Health Authority where the plane is expected to land.

Flight and cabin crew should follow airline guidelines for preventing spread of infection when interacting with these travelers.
