Patients and visitors

More in this section

There has been an increase in the number of measles cases in London and the south east. Guy’s and St Thomas’ has seen a small number of cases in the past few weeks among our patients and our staff.

We will do everything we can to prevent measles passing from one person to another, and you may be asked to wear a facemask and move to a private room when being assessed.

You are not at risk of getting measles if you:

  • have had two MMR jabs (the measles, mumps and rubella vaccination introduced in 1988)
  • have had a blood test showing you are immune to measles
  • have had measles in the past, particularly if you were born before 1970.

If you have visited our hospitals, particularly the emergency department (A&E) at St Thomas’ or the Urgent Care Centre at Guy’s in the past few weeks, there is a small chance you may have been exposed to the measles virus. Please be aware that measles develops around 10 days after a person is infected.


  • Cold-like symptoms, such as a runny nose, sneezing, cough.
  • Sore, red eyes that may be sensitive to light.
  • A high temperature.
  • A rash – this will appear a few days later, usually starting on the head before spreading elsewhere. Please be aware that you are infected up to four days before the rash appears.

If you have these symptoms, please contact your GP or NHS 111. Further information is available on the NHS website.

If you are due to visit our hospitals and suspect you may have measles, please tell a member of staff before coming to your appointment.

Nurse using hand gel

Our staff use a six step hand washing technique, and we encourage patients and visitors to do the same.
