The 25-year-old, named locally as Gareth Williams, was found dead at a flat on Thursday.
Public Health Wales (PHW), which is tackling an epidemic of more than 800 cases, said tests confirmed only that the man had measles at the time of his death.
If confirmed, it would be the first death in the measles epidemic.
808 cases of measles have been confirmed so far in the Swansea epidemic. MMR vaccines for those who have not had two are being offered in schools in Wales. But not enough people are getting them. Thanks Andrew Wakefield.
Discredited researcher, former doctor, Andrew Wakefield was responsible for lighting and stoking the fear over vaccinations in the U.K. that resulted in a decline in vaccination rates. This lowered rate of vaccination certainly played a part in the spread in Wales. Wakefield, however, blames the government and still contends there is a connection between the MMR vaccine and autism after numerous solid studies have show this is untrue. Rates are on their way back up. Hopefully.
This news of a probable preventable death may lead to more getting vaccinated.
