How to spot the first symptoms of an infection
MEASLES starts with cold-like symptoms, including a runny nose, sneezing, watery eyes, swollen eyelids and a high temperature.
These begin to develop within 10 days after the infection.
A day or two before the measles rash appears, many people develop small greyish-white spots in their mouth.
The rash is made up of small red-brown, flat or slightly raised spots and may join together into larger blotchy patches.
It appears around two to four days after the first symptoms and normally fades after about a week.
For most, the illness lasts from seven to 10 days.
If you think you may have measles, health officials recommend avoiding work, school or crèche.
Individuals should stop visitors coming to the house to prevent the illness spreading.
