Symptoms of measles
Measles starts with cold-like symptoms that develop about 10 days after becoming infected. This is followed a few days later by the measles rash.
For most people, the illness lasts around 7 to 10 days in total.
The initial symptoms of measles can include:
A day or two before the rash appears, many people with measles develop small greyish-white spots in their mouth.
Not everyone with measles has these spots, but if someone has them in addition to the other symptoms listed above or a rash, it's highly likely they have the condition.
The spots will usually last for a few days.
The measles rash appears around two to four days after the initial symptoms and normally fades after about a week.
You'll usually feel most ill on the first or second day after the rash develops.
Contact your GP as soon as possible if you suspect that you or your child has measles, even if you're not completely sure.
It's best to phone before your visit, as your GP surgery may need to make arrangements to reduce the risk of spreading the infection to others.
You should also see your GP if you've been in close contact with someone who has measles and you've not been fully vaccinated or haven't had the infection before – even if you don't have any symptoms yet.
