Air China Flight 112 was a scheduled international passenger flight on 15 March 2003 that carried a 72-year-old man infected with severe acute respiratory syndrome (SARS). This man would later become the index passenger for the infection of another 20 passengers and two aircraft crew, resulting in the dissemination of SARS north to inner Mongolia and south to Thailand. The incident demonstrated how a single person could spread disease via air travel and was one of a number of superspreading events in the global spread of SARS in 2003. The speed of air travel and the multidirectional routes taken by affected passengers accelerated the spread of SARS with a consequential response from the World Health Organization (WHO), the aviation industry and the public.[3][4][5]
The incident was atypical, in that passengers sitting at a distance from the index passenger were affected and the flight was only three hours long. Until this event, it was thought that there was only a significant risk of infection in flights of more than eight hours duration and in just the two adjacent seating rows. Other flights at the time with confirmed passengers with SARS did not have the same extent of infection spread.[3]
Some experts have questioned the interpretation of the incident and highlighted that some passengers may have been infected already. The role of cabin air has also come under question and the incident involving Flight 112 has led to some experts calling for further research into patterns of airborne transmission on commercial flights.[6]
