Which combination of measures most effectively reduces cross-contamination risk during aeromedical transport of infectious patients?

• A. Use basic gloves only
• B. Isolate if possible, use proper PPE, minimize aerosol-generating procedures, and ensure thorough decontamination of surfaces and equipment
• C. Move quickly without PPE
• D. Only decontaminate after arrival

Answer: (B)

In aeromedical transport, the key idea is to prevent exposure at all stages—from the patient to the cabin environment and crew—through source control, protection, minimization of aerosol production, and rigorous cleaning. The best approach combines isolating the infectious patient when possible, using proper personal protective equipment, reducing procedures that generate aerosols, and thoroughly decontaminating all surfaces and equipment after the transport. Isolating the patient helps limit environmental contamination. Proper PPE—gloves, gown, eye or face protection, and an appropriate respirator or PAPR—protects crew from droplets and aerosols in the confined aircraft cabin. Minimizing aerosol-generating procedures reduces the amount of infectious material released into the cabin air. Thorough decontamination of surfaces and equipment ensures any residual contamination is removed before the next patient or crew member is exposed. Why the other options fall short: basic gloves alone leave skin unprotected against contaminated contact and droplets; moving quickly without PPE fails to provide necessary protection in an environment with close quarters and potential aerosols; decontaminating only after arrival allows in-flight exposure and risks spreading contamination to the aircraft and crew. In short, this combined approach addresses exposure before, during, and after transport, which is essential in the aeromedical setting.
