It's believed there are a further four cases of measles in South West Wales. Public Health Wales say there are now seven cases associated with Cwmtawe School in Neath Port Talbot, two of which have been confirmed in laboratory tests.
Last week, two cases were identified in children in another school in Powys, and these are connected to one of the confirmed cases at Cwmtawe School.
Public health officials fear that youngsters in South West Wales could face a new outbreak of measles because hundreds of children are still not fully immunised.
Today they began vaccinating at Cwmtawe school in Pontardawe after one confirmed case and two suspected cases were diagnosed there. A further two cases are suspected at a school at Abercrave, further up the Swansea Valley. Rob Osborne reports.

It is just three months after the end of Wales's biggest ever measles outbreak, which was also centred on the Swansea area.
More than 1,200 people contracted measles, 88 serious enough to visit hospital, and one person died.

The symptoms of measles include a fever, fatigue, runny nose, pink eyes and a distinctive red rash.
Doctors are urging parents to keep children at home if they suspect measles and to seek medical advice.
They say that any unvaccinated children should receive the MMR jab as soon as possible.

This cluster of measles cases comes only three months after the end of Wales’s biggest ever measles outbreak, which was centred on the Abertawe Bro Morgannwg Health Board area, so we are obviously concerned and want to act quickly. Although we vaccinated more than 75,000 people during the outbreak, we are aware of more than 30,000 children in the 10 to 18 age group who remain unvaccinated in Wales and have always warned that this could lead to another outbreak.
– Dr Jorg Hoffmann, Public Health Wales
We have written to all parents of unvaccinated children in Cwmtawe School and Ysgol Y Cribarth to urge them to arrange for their children to be vaccinated.
In the meantime, to prevent the spread of infection, we would urge parents of any children who become unwell with measles-like symptoms over the weekend to keep them at home and seek medical advice, and not to allow them to attend events where other children will be present
Health Minister Mark Drakeford AM says the Welsh Government and local health board are well versed in dealing with measles after the Swansea outbreak. He says they are aiming to 'get on top' of what he described as a 'small outbreak' before it gets any bigger.
Public health officials say a decision will be made today on when more than 200 children in the Neath Port Talbot area will receive MMR vaccinations.
Laboratory tests last week confirmed a child at Cwmtawe Comprehensive School had contracted measles.

The measles outbreak centred on the Swansea area has been declared over eight months after it began.
Public Health Wales has announced that there have been no laboratory confirmed measles cases linked to the outbreak area since 22 May, indicating that the outbreak is now over.
The outbreak began in November 2012 and resulted in 1,219 cases, 88 people visited a hospital due to measles during the outbreak and one person died.
Efforts to bring the outbreak to an end have seen 75,868 unscheduled MMR vaccinations given at GP surgeries, weekend drop-in sessions and schools and occupational health vaccination sessions in Wales during the outbreak period.
But Public Health Wales is warning that there are still around 30,000 unvaccinated children in the 10 to 18 age group across Wales, and that there is still a possibility of a further outbreak in the future.
A young father who died in the South Wales measles epidemic failed to have an inoculation as a child, an inquest has heard. Dad-of-one Gareth Colfer-Williams, 25, was among more than 1,200 infected by measles in the outbreak but the only one to die.
An inquest heard how Gareth was found dead at his home in Port Tennant, Swansea, by family members - days after being sent home by doctors. Swansea Coroner's Court heard he had visited the doctors complaining of a rash all over his body.
But he was told to go home and take paracetamol - even though he had not had the MMR jab in his life. Coroner Philip Rogers said his partner reported he had a high temperature and rash all over his body and was suffering hallucinations.
"Somebody stayed up until about 3.30am and then at 7.45am the same day that family member returned and found him dead on the sofa. An ambulance was called but unfortunately nothing could be done. Swansea was in a measles epidemic and his death was due to natural causes, " said Mr Rogers.
Unemployed Mr Colfer-Williams lived in Port Tennant, Swansea, with his fiancee Cairo Oneim and their four-year-old daughter Dakota. Gareth was concerned about his daughter and made sure she had the jab but failed to have himself immunised.
Pathologist Dr Maurizio Brotto said Gareth was "very underweight" at just 7st 7lbs and that he died from giant cell pneumonia caused by measles. The inquest heard that Gareth had suffered from alcohol problems and two weeks before he had gone into detox leaving his body vulnerable.
A verdict of natural death was recorded following Gareth's death in April. Speaking after the case his mother Angela Colfer said: "He was a wonderful son and a wonderful father, uncle and brother. Cairo and Dakota are having a terrible time. They are devastated."
