Improving LLIN utilization and coverage through an innovative distribution and malaria education model: a pilot study in Okavango Sub-District, Botswana

Materials and methods Okavango Sub-District experienced the highest malaria burden in the country (36% of total burden) and was thus chosen as the pilot site. After comprehensive training, sub-district health staff distributed 32,000 LLINs free of charge door-to-door in 2009 and an additional 6,500 LLINs in 2010 and offered hanging assistance with kits of hooks and strings to households. All nets distributed were mapped by household. Both distributions were supported by health education campaigns, including household visits, roadshows, and calendar posters. Two surveys in 2009 and 2010 evaluated pilot outcomes using a structured questionnaire to interview 557 and 362 randomly selected households in Okavango. Findings from the pilot study informed scale up of LLINs throughout Botswana.
