About this study
This study will:

1. Test Ontarians for antibodies to the H1N1 ‘swine’ flu virus

If you have antibodies to the H1N1 ‘swine’ flu virus it usually means that you have at some time been infected with the virus.

Having antibodies does not mean that you have been sick or will become sick. Some people who are infected with the virus do not have symptoms of illness.

Having antibodies may mean that you have some protection against the H1N1 ‘swine’ flu virus and are unlikely to become infected again. For more information, visit About the H1N1 'swine' flu virus.

Knowing how many Ontarians have been infected with the H1N1 ‘swine’ flu virus will help us to understand how many people are likely to get sick from the virus in the future.


2. Determine risk factors for infection by the H1N1 ‘swine’ flu virus

We want to know if factors such as your age, education or medical history make you more likely to be infected with the H1N1 ‘swine’ flu virus. We also want to know if the activities you’ve done while in Ontario or while travelling in Mexico have exposed you to the virus.

Knowing what factors or activities increase the risk of infection by the H1N1 ‘swine’ flu virus will help us to manage the spread of the virus in the future.
