The IDHS should contact the flight surgeon when a patient has any fever at what temperature?

• A. 101 F
• B. 102 F
• C. 100 F
• D. 103 F

Answer: (D)

Fever is a sign that a systemic illness could affect how a crewmember performs in flight and may pose contagion risk in the closed cabin environment. When fever reaches 103°F (39.4°C) or higher, it triggers escalation to the flight surgeon for evaluation and potential grounding. At lower fever levels (around 100–102°F), symptoms may be milder and could often be monitored and managed on the ground if the patient is stable and there are no concerning signs. The 103°F threshold is chosen because it represents a level at which the likelihood of impairment, dehydration, or illness progression becomes significant enough to warrant professional medical assessment before flying.
