How should an infectious disease risk be managed on board?

• A. Do not report symptoms
• B. Isolate if required
• C. Notify the flight deck
• D. Notify the flight deck, isolate if required, implement hygiene measures, and coordinate with health authorities on landing.

Answer: (D)

Managing an infectious disease risk on board relies on a layered, proactive approach that protects everyone on board and ensures proper medical follow‑up after landing. The most effective response combines clear communication, containment, hygiene, and coordination with health authorities.

Notify the flight deck so the captain is aware of the situation and can coordinate any required in‑flight actions, ventilation controls, and procedures to minimize exposure. If isolation is needed, implement it promptly to limit contact with others, using any available isolation space or procedures to separate the affected person from the rest of the cabin.

Put hygiene measures in place across the cabin: reinforce hand hygiene, increase cleaning and disinfection of touched surfaces, manage waste appropriately, and ensure appropriate use of personal protective equipment by crew as available. These steps reduce transmission risk during the flight.

Coordinate with health authorities on landing: provide medical handover and passenger/crew information as required, arrange for appropriate medical care upon arrival, and follow any regulatory reporting or public health directives. This ensures a safe in-flight environment and a proper, compliant medical transition after landing.

Together, these elements address immediate risk, limit spread, and connect with external medical support and reporting.
