Measles

Measles is a highly contagious viral infection. It can cause serious complications, including pneumonia and inflammation of the brain, especially in young children and other vulnerable people. Outbreaks occur in many parts of the world, so exposure can happen during travel even to places where measles is usually uncommon.

Prevention: Vaccine

Symptoms

  • Fever, cough and a runny nose
  • Red or watery eyes
  • A blotchy rash that usually begins on the face and spreads down the body
  • Sometimes small pale spots inside the mouth

Transmission

  • Infectious particles in the air and respiratory droplets
  • An infected person can spread measles before the rash appears

Prevention

Vaccination is the main protection. Check that you and your family have appropriate protection under your local programme, particularly before travel. After possible exposure, contact a healthcare professional promptly because time-sensitive preventive measures may be available.

Diagnosis and care

If measles is suspected, contact a healthcare service before attending so they can reduce exposure to others. Care focuses on symptoms and complications; breathing difficulty or a seriously unwell child requires urgent attention.
