High risk exposure to HIV among sexually active individuals who tested negative on rapid HIV tests in the Tshwane District of South Africa—the importance of behavioural prevention measures

S1 Fig. Questionnaire. A questionnaire tool that was used to collect demographic and HIV risk factors from the study participants. Codes (in red) were used to capture questionnaire data into the Excel spreadsheet. N/AÐnot applicable was used for participants who had no recent sexually transmitted diseases (number 12) and this also applied for parameters on number 18 and 19. Questionnaire parameters (numbers 5, 6, 8, 15 and 18) that were not applicable to the whole general or pregnant population group were not included in the group's analysis but some of them were analysed separately.
