The Health Protection Agency (HPA) has called for parents to protect children who are going away on school trips or family holidays by making sure they have been immunised with two doses of the MMR vaccine.
Since the beginning of 2011 there have been 275 confirmed cases of measles reported to the HPA between January and April, compared to 33 cases over the same period last year.
Cases of the illness have been linked to either travelling abroad or small clusters in mainly unvaccinated children and young adults aged between 10 and 24.
Dr Mary Ramsay, Head of the Immunisation Department at the Health Protection Agency, said: "The recent upsurge in cases is probably related to recent travel to and from Europe. This means that measles can spread easily in schools, summer camps and universities among children and young adults who are not fully immunised.
"We again are reminding parents to remain vigilant against measles and that it's never too late to get your child immunised with two doses of the MMR vaccine. We cannot stress enough that measles is serious and in some cases it can be fatal. Delaying immunisation puts children at risk."
We asked if you agree with the HPA. Your comments (terms and conditions apply):
"No, I do not agree with the HPA. Common sense dictates combining three viral vaccines into a single combination can seriously increase the immunosuppressive viral response causing more problems than the disease itself. It is time for all medical professionals to wake up to the downside of current vaccination policy" - Jane Dean, London
"I do agree but I have a problem with what is the age range? Does it go up to a 60 yr old travelling to Turkey?" - Lisa Kitchen, Leeds
