Despite worldwide efforts to prevent malaria, the disease continues to take its strongest toll in sub-Saharan Africa. Kenya is no exception, with millions of cases and thousands of deaths reported annually. This pilot study looks at knowledge on malaria prevention and treatment among peri-urban communities in Western Kenya. Through a study on the use of animated videos as an informal educational tool, we examine baseline knowledge, sources of knowledge, and learning gains on a range of knowledge points on malaria prevention and treatment. The study has three significant findings: 1) participants in this study had relatively high levels of knowledge on malaria before the video intervention, 2) although the trend was an increase of correct answers post-animation viewing for all questions, and in some cases this went to 100% correct answers, the pre-knowledge levels were high enough for most questions that statistical significance was only detected in one question, and 3) we detected a significant correlation between Internet usage and baseline knowledge on malaria among the mostly literate sample population. These findings suggest that in heavily sensitized populations, for a particular topic, educational animations can be used to 'top off' knowledge on a given topic. Findings from this study can guide future malaria prevention and education efforts in Kenya and other developing nations.
