Abstract

Researchers investigated public perception, anxiety, and behaviour with regard to the outbreak of swine flu.1 A cross sectional survey was used, with random dialling of telephone numbers in England, Scotland, and Wales. In total, 997 adults aged over 18 years—who had heard of swine flu and spoke English—were interviewed between 8 May and 12 May 2009. Proportional quota sampling was used with quotas based on age, sex, work status, region, and social grade. Which of the following statements, if any, are true?
