WellKiwis Household Study

The WellKiwis Household Study follows families for up to seven years to understand how previous flu infections or vaccinations shape future immunity. It is also helping researchers learn how flu and other respiratory viruses spread between people living in the same home.

Household Transmission Study

The Household Transmission study involves monitoring of your household and their experience while infected with the flu. Your household will be invited to participate in this extra study activity if you or a member of your household return a positive influenza swab result.

This involves:

• Daily surveying of symptoms.

• Swabbing every three days until a negative swab is returned or for up to 28 days

• Two blood samples from each participant (an acute blood sample within the first two weeks following a flu positive result, a convalescent blood sample three to seven weeks later).

• Exit questionnaire for the household representative.

Eligibility to participate in the Household Transmission study requires all members of your household to participate in the WellKiwis Household study and be living in the home at the time of the flu positive result.
