*Odds ratios adjusted for all variables shown. LPMs, live poultry markets; SARS, severe acute respiratory syndrome.
†Respondents were asked, “How likely do you think it is that you will contract H7N9 avian flu over the next 1 month?” Low indicates the answers Never/Very unlikely/Unlikely; evens, the answer Same (50% probability); and high, the answers Likely/Very likely/Certain.
‡Respondents were asked, “What do you think are your chances of getting H7N9 avian flu over the next 1 month compared to other people outside your family of a similar age?” Low indicates the answers Not at all/Much less/Less; evens, the answer Same (50% probability); and high, the answers Likely/Very likely/Certain or More/Much more/Certain.
§Respondents were asked, “If you were to develop flu-like symptoms tomorrow, would you be…” followed by several choices.
