A school based measles vaccination programme has started in schools across Teesside, after the number of cases increased again.
There have been 150 confirmed cases of measles in the North East since the recent outbreak.
Almost all the reported cases are on Teesside, with just three in County Durham and none in Newcastle or Gateshead.
The NHS is advising people to contact their GP about vaccinating their children, or to take advantage of the schools programmes.
