A further 43 cases of measles have been reported to Public Health Wales since Tuesday. A total of 77 people have been hospitalised since the beginning of the outbreak with a total of 808 cases now reported since the outbreak began.
Although children of all ages are being affected by the outbreak, the highest numbers of cases are being seen in those aged between 10 and 18 who would have missed routine vaccinations as small children.
The number of children diagnosed with measles in South Wales has risen to nearly 800.
Today the Health Secretary, Jeremy Hunt, urged parents in England, to get their children vaccinated amid concerns the infection will spread.
The Health Secretary Jeremy Hunt has told MPs that the work of the Dr Andrew Wakefield caused "huge damage and worry to thousands of parents".
Research published by the Dr Andrew Wakefield in 1998 suggested a link between the triple vaccine for measles, mumps and rubella and autism.
Published in the respected Lancet medical journal, the report received widespread media attention and lead to a significant decline in children being given the MMR vaccine.
But concerns were raised when other scientists failed to recreate his results and the General Medical Council launched a review of the research.
The Sunday Times journalist Brian Deer exposed significant flaws in Dr Wakefield's research and ethical practices.
Following an extensive investigation in 2010, the General Medical Council struck Dr Wakefield off the medical register, describing him as "dishonest", "unethical" and "callous".
Dr Sarah Wollaston MP has made a heartfelt plea to her constituents to get their children vaccinated following an outbreak of measles in Wales.
The Devon MP who was a practising GP before her election, wrote on her blog that many of her constituents mistakenly believed that homeopathy would protect their children.
The British Homeopathic Association said that there was no evidence to suggest that homeopathy should be used to prevent measles and stressed that parents should give their children the MMR vaccine.
Extra vaccination clinics are being opened across South Wales after cases of measles were confirmed in Merthyr Tydfil and Rhondda Cyon Taf.
Cwm Taf Health Board said that all health boards in Wales are "are developing plans to vaccinate unprotected children and young people and to provide rapid implementation of school based immunisation in response to cases and outbreaks".
A global scare sparked by the "discredited and inaccurate" claims of a doctor 15 years ago over the MMR vaccine have caused huge worry to parents in South Wales following a measles epidemic in the region, Health Secretary Jeremy Hunt said.
Mr Hunt said Dr Andrew Wakefield's comments about the vaccination had "absolutely no scientific basis" as he urged parents of children who had not been given two doses to contact their local GP as soon as possible.
Mr Hunt told the Commons, "What Andrew Wakefield said had absolutely no scientific basis and has caused huge damage and huge worry to many thousands of parents".
"It is very important to reiterate that the scientific way to prevent measles, which can be a horrible, even fatal disease, is to make sure that you have had two doses of MMR", he continued.
"Parents of children who have not had those doses, parents of children of any age, should contact their GP if they have not had those two doses, particularly in the current circumstances".
Public Health Wales says there are now cases of measles in every health board area in Wales.
Dr Marion Lyons, Director of Health Protection, says "we have no way of knowing where the outbreak might spread."
