A 14 year-old Niagara Falls girl who had not been vaccinated is the second person in that city to be diagnosed with measles. The girl is related to a woman previously found to have the disease. She had been not been vaccinated either. The two are connected in some way, a break for health authorities in tracking how new cases are spread. In Toronto, two adults have been diagnosed. The vaccination history is not clear in these cases. In total, there are now 11 cases of measles in Ontario.
