Measles (Rubeola)

★ CMTO Exam Focus

Measles is a highly contagious acute viral infection caused by Morbillivirus (paramyxovirus family), with a reproduction number (R0) of 12-18, making it one of the most infectious diseases known. The virus spreads via airborne droplets and remains infectious in a room for up to 2 hours after an infected person has left. Complications include pneumonia (most common cause of measles death), encephalitis, and the rare but fatal subacute sclerosing panencephalitis (SSPE).

Recognition

  • Prodrome: High fever (often >104F), cough, coryza (runny nose), conjunctivitis (the "three C's")
  • Koplik spots: Pathognomonic white spots on the buccal mucosa appearing 1-2 days before the rash — if present, diagnosis is confirmed
  • Rash: Maculopapular rash beginning at the hairline and spreading cephalocaudally (head to toe) over 3-4 days. Rash lasts 7-10 days
  • Incubation: 10-14 days from exposure to prodrome onset
  • Contagious period: From 4 days before to 4 days after rash onset
  • Reportable disease in Ontario. Suspected cases require immediate public health reporting

MT Relevance

  • Systemic contraindication: Acute measles systemically contraindicates massage — the client is febrile, systemically unwell, and highly infectious
  • Contagion risk: The virus remains airborne in a room for up to 2 hours. Standard PPE is insufficient without airborne precautions
  • Immunocompromised clients: Be alert when treating immunosuppressed clients. They are at risk for severe complications from exposure
  • Return to treatment: Massage may resume once the client is afebrile, the rash has fully resolved, and the client is cleared by a physician

Required Actions

  • Refer to a physician immediately if measles is suspected — reportable disease
  • Do not treat during active infection
  • Notify clinic management if a client with suspected measles was present in the treatment space (airborne exposure risk for 2 hours)

Key Takeaways

  • Measles is caused by Morbillivirus. Airborne transmission. Incubation 10-14 days. R0 of 12-18.
  • Classic prodrome: high fever + three C's (cough, coryza, conjunctivitis). Koplik spots are pathognomonic.
  • Maculopapular rash spreads cephalocaudally, beginning at the hairline.
  • Measles is a reportable disease in Ontario. Suspected cases require immediate physician referral.
  • Acute measles is a systemic contraindication. The virus remains airborne and infectious for up to 2 hours.
