CAPSCA is being extended to cover public health emergencies other than those relating to a communicable disease, i.e. nuclear and chemical events.
When the Fukushima accident happened, it raised questions concerning the health and operational risks involved should an aircraft inadvertently fly through a radioactive plume, the correct procedure if a parked aircraft is covered by radioactive dust, or risks to other passengers if an individual exposed to radiation needs to travel by air in order to obtain specialized treatment, as well as several other issues.
Experience during this accident demonstrated that the network already established for communicable disease preparedness was useful in helping to manage the aviation aspects and was able to provide up to date, authoritative and generally reassuring news releases that were jointly written by all major agencies involved (including seven UN specialized agencies and two trade associations).
