Campylobacter Hypothesis Generating Questionnaire

Case ID: National ID:

Questionnaire Background for Interviewer

This questionnaire is designed to collect comprehensive information on possible risk factors for campylobacteriosis. It is designed for cluster/outbreak investigations where the source of infection is unknown, but the questionnaire could be applied to investigate sporadic cases.

Data captured: – Case demographics – Food exposures

– Clinical information – Animal exposures

– Laboratory information – Other risk factors

Since outbreaks of campylobacteriosis are often linked back to contaminated food products, it is critical to collect as much detail as possible on food exposures. Therefore, this questionnaire has an open ended food history followed by a detailed check list of food items; this may seem repetitive, but is used to ensure all possible food exposures are captured. Please collect as much detail as possible for each item, including restaurant exposures. Also consider using a calendar to probe and collecting receipts, purchase data or loyalty cards if available.

The questionnaire is estimated to take 45 – 60 minutes to complete.

Section 11: Demographics

My final question asks about your race or racial background. In our society, people are often described by their race and consider themselves to be “White” or “Black” or “South Asian”. This information is being collected to understand who is being infected with Campylobacter to help guide our investigation.

(Interviewer note: if a case is uncomfortable with answering, skip the question).

Which race category best describes you? Select all that apply from the options:

☐ Black (e.g. African, Afro-Caribbean, African Canadian descent)

☐ East/Southeast Asian (e.g., Chinese, Korean, Japanese, Taiwanese, Filipino, Vietnamese, Cambodian, Thai, Indonesian, other Southeast Asian descent)

☐ Indigenous (e.g. First Nations, Inuk/Inuit, Métis descent): ☐ First Nations ☐ Inuk/Inuit ☐ Métis

☐ Latino (e.g. Latin American, Hispanic descent)

☐ Middle Eastern (e.g. Arab, Persian, West Asian descent – for example, Afghan, Egyptian, Iranian, Lebanese, Turkish, Kurdish)

☐ South Asian (e.g. South Asian descent-for example, East Indian, Pakistani, Bangladeshi, Sri Lankan, Indo-Caribbean)
