TORONTO - The measles count in Ontario rose Thursday, with health officials in Toronto reporting they found another adult infected with the highly contagious disease.

The infected person had received the recommended two doses of vaccine, said Lenore Bromley, media relations manager for Toronto Public Health. While the measles vaccine is considered highly effective, about five per cent of people who get two doses may not be fully protected.
