- Primary Outcome Measures
Name Time Method Percentages of households infested with O. moubata s.l. (domestic infestations with the soft tick vector of TBRF), numbers of O. moubata s.l. per house (tick-density) and incidence of Borrelia infections in under five year-old children. Surveys were carried out at baseline, with five follow-ups at 3, 7, 15, 18 and 25 months post-intervention.
- Secondary Outcome Measures
Name Time Method sing a structured questionnaire, studies on knowledge, attitudes, perceptions and behaviours with regard to the efficacy of ITNs in reducing tick infestations and tick-biting and their perceived benefits were conducted in April 2004 (14 months after the trial began) and at the end of the trial (April 2005). In the latter study, behaviours in the control households and the practice of anti-tick activities were additionally investigated in response to perceived anomalies in the data collected in the previous 12 months.
