Public health Ontario Said 173 other people were infected with measles in the province in last week, bringing the number of cases to 1,795 since the start of the epidemic last October.
“This is 173 cases that we do not want to see,” said Dr. Sarah Wilson, a public health doctor of the agency.
Ontario’s weekly health of public health measles, published on Thursday, said the virus continues to spread mainly among people who had not been vaccinated.
“Eighty-five percent of the cases are either non-immunized or with a history of unknown immunization, and three-quarters of epidemic cases are in young people under the age of 20, so measles (IS) has an impact on babies, children and adolescents,” said Wilson.
