Adverse events and acceptability
ADVERSE EVENTS, BEDBUGS, LICE
The summary results of adverse events reported by inhabitants of sprayed households and spray operators are presented in Fig. Proportion of adverse events reported in VECTRON™ T500 and Fludora® Fusion arms by spray operators and householders.The main factors that influenced the acceptance of spraying were generally the same at surveys conducted immediately after the IRS and 6 months after irrespective of the study arms. Overall, the desire to reduce the mosquito population and other pests such as bedbugs, lice, flies, cockroaches, etc. in homes were the most frequent reasons put forward by the study participants. A small proportion of study participants (14%) from both study arms were concerned for the health of children and adults sleeping in sprayed homes in the survey conducted immediately after IRS, but these concerns were no longer raised at 6 months post-spray. Nevertheless, the difficulties in removing personal belongings and disruption of daily activities on the day of spray operations were raised at both acceptability surveys (just after IRS and 6 months later) in both study arms. Feedback received from heads of household about their perceptions of the effectiveness of the IRS products remained very positive at 6 months post-intervention survey for both study arms; over 90% reported that the IRS intervention was either excellent or good for them.
