  • Consider enhanced surveillance for ill passengers.

Extensive transmission/effective control measures 

  • Implement active surveillance for ill passengers.
  • Implement symptom screening for all arriving passengers.
  • Medically evaluate all passengers with symptoms.
  • Consider 10-day quarantine for asymptomatic arrivals.
