CALGARY - There are three new confirmed cases of West Nile virus in Alberta.

These new cases are all women and include one person in Calgary, one in central Alberta and one in the north.

Alberta Health Services says the province now has a total of four confirmed cases, one which is neurological, and three that are the less serious non-neurological.

The government agency is again urging people to take simple precautions to prevent mosquito bites, such as wearing insect repellent.

The latest Public Health Agency of Canada figures show 71 cases of West Nile infection across the country so far this year.

That compares to 102 cases reported last year.
