On Monday, three new cases of the H1N1 virus were confirmed, bringing the total to 52 confirmed cases of H1N1 in Alberta.

Currently, 18 cases are from the Calgary area, 15 are from the Edmonton area, 12 from central Alberta, and seven are from northern Alberta.

Health officials said mild symptoms have been reported for all but two cases.

Of the 52 confirmed cases, 28 people had travelled to affected areas and eight had contact with travellers to Mexico.

11 people had not travelled recently and five cases have not yet reported if they had or hadn't travelled recently.

On Saturday, the province announced that nearly a quarter of the pigs on a farm under H1N1 quarantine had been killed.

According to Dr. Gerald Hauer, the province's chief veterinarian, the decision was made to prevent possible overcrowding at the farm near Rocky Mountain House, which was risking overcapacity because the producer is prohibited from shipping hogs to market.

Almost 500 pigs in a herd of 2,200 were culled, many of which were assessed as either healthy or recovering from flu symptoms.

The decision was made after discussions between the producer, the Canadian Food Inspection Agency and provincial and federal animal health officials

And last week, Alberta health officials confirmed the first death associated with the H1N1 virus.

The woman, in her 30s from Gift Lake Metis Settlement near High Prairie, had the virus, but it's not clear how the virus is related to her death. It's been previously determined that she suffered from chronic pre-existing medical conditions, including asthma.

It is not clear to what extent H1N1 may or may not have contributed to her death and it may never be clear," said Dr. Andr� Corriveau, the chief medical officer of health for Alberta.

This week, it's expected that a pathologist will determine just how the flu contributed to the woman's death.
