Parents of primary school children at Ysgol Clawdd Offa, Prestatyn, have been directly informed of the signs and symptoms of measles; One of the cases examined has been in school while infectious.
Dr. Chris Johnson, consultant in Health Protection, said: "At the moment we are not investigating an outbreak of measles as there is no evidence that measles has spread beyond a closely linked group of people. that measles spread quickly and easily between unvaccinated people, and we have concerns that others may have been exposed to the infection in the cinema, restaurant or health care system last weekend.
"We always recommend anyone who has not been fully vaccinated with two doses of MMR to ensure that they are protected from measles, which can be very serious and potentially fatal.
"When summer vacations come up and people attend big events and holidays in countries where measles are common, we will especially encourage everyone to ensure that they and their children have received the MMR vaccine."
Measles are highly contagious and easily spread to non-vaccinated people. These include a high temperature, cough, runny nose, red eyes (conjunctivitis) and a special red rash that begins at the back of the head and spreads on the face and forward in the body.
Rashes are typically seen three to five days after symptom onset.
