With 335 confirmed cases of the H1N1 flu in the Ottawa area, precautions to prevent spreading are sweeping the region.

Several camps and community services are doing extra screenings before accepting children into their programs.

"When they arrived we talked to the parents, asked them if they have showed any symptoms that are typical of H1N1 virus," said vice-president of the YMCA/YWCA Deidre Spears.

Campers are advised to wash their hands frequently and use hand sanitizer before meals.

Ottawa Public Health officials say while H1N1 poses a larger threat to younger generations, everyone is at risk.

"We are all vulnerable to a new strain of influenza," says Dr. Vera Etches "What we're seeing is most of the cases are in people under the age 60, under 65, so that is a bit different from the usual seasonal influenza rates."

Many of the 36 Canadians who lost their lives to the flu had underlying health conditions.

"A lot of them are asthma, chronic condition of the long, people with diabetes, pregnant women are in that group, so underlying conditions are quite common and they're really not that severe in their own in many cases," says University of Ottawa immunology professor Earl Brown.

Public health officials say, though most Ottawa cases are mild, they are expecting the situation to get worse before it gets better.

Fingers are crossed for a flu vaccine before the big flu season in the fall.
