Pairs of researchers from our team would work with each pair of participants to facilitate this process, integrating three main areas of questioning in relation to the contextual image, namely:1. How does your job role impact on the spread of pathogens? (talk through and writeon image if desired, using black pen.)2. Locate where pathogens might be found (talk through and use green stickers andpens to mark on image).3. Locate where the high-risk areas for pathogens are (talk through and use redstickers and pens to mark on image).
