What happens if someone near me on the flight is taken ill?
Passengers who were seated in the same section of aircraft with the suspected case, as defined by seat configuration, are considered close contacts of the suspected COVID-19 case. They might need to be interviewed by the entry country public health authorities if the suspected case is confirmed. Depending on the configuration (e.g. if the entire cabin of the aircraft is one section) it may in fact mean all the passengers in the particular flight. In addition, if contact tracing discovers >1 new case among the passengers, then contact tracing of all the passengers in the particular flight should be considered.
After the aircraft has landed and all the other passengers have disembarked, the isolated symptomatic passenger, and where applicable their companion(s), should be disembarked and managed in accordance with the instructions provided by the local public health authorities.
