This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Measles: For health professionals. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Isolate immediately and contact public health before bringing a suspected measles case through a shared waiting area.
  • Use exposure, immunization, travel, fever, cough, coryza, conjunctivitis and rash timing to support suspicion and coordinate testing.
  • Work with public health on airborne precautions, case confirmation and time-sensitive post-exposure prophylaxis for contacts.
  • Notify public health on suspicion rather than waiting for laboratory confirmation.

Practical assessment and management workflow

1
Identify fever, cough, coryza, conjunctivitis, rash timing, immunization and travel or contact exposure.
2
Mask and isolate immediately using airborne precautions and avoid routine waiting-room exposure.
3
Coordinate the correct respiratory and urine specimens with public health.
4
Assess contacts rapidly for post-exposure vaccination or immune globulin eligibility.

Safety, red flags and urgent escalation

  • Respiratory compromise, encephalitis, dehydration or pregnancy and immune complications need urgent hospital care.
  • Do not send a suspected case unannounced to another facility.
  • Verify vitamin A treatment and dosing only through pediatric or public-health guidance for severe disease.
