Infectious Diseases
Because the aircraft cabin is a confined space and flights may be of many
hours duration, there is the risk of a contagious disease being passed from one
passenger to another. This can occur when an infected passenger releases
organisms into the air by breathing, coughing or sneezing. The risk of such
person-to-person contact of course is much greater for those passengers sitting
next to or very near the passenger with the illness. Therefore, the risk of
transmission of illness in an aircraft is no different from in any confined space
including a room, office, train, or bus
