Canada's swine flu case count has jumped nearly 20 per cent since Wednesday, largely due to a rise in cases in Ontario.

The Public Health Agency of Canada says there are 1,336 cases in nine provinces and two territories and two deaths as of Friday.

That's an increase of 218 cases since Wednesday, when the agency last reported the number of confirmed infections with the new H1N1 virus.

The main increase in activity is occurring in Ontario, where the count rose by 131 cases to 626.

Quebec saw the second largest increase, up 46 cases to 253.

As of Friday, the World Health Organization reported 15,510 cases and 99 deaths in 53 countries.
