Heatmaps indicating the number of respondents (n = 196) for each level of agreement to 10 statements (a-j), on two interview occasions in a longitudinal interview study conducted on household level in northern Uganda between 2014 and 2015. The level of agreement with the given statements was recorded on a Likert-scale with five levels: strongly agree = 5; agree = 4; neither agree nor disagree = 3; Disagree = 2; Strongly disagree = 1. The statements were: a I think it is possible to protect my pigs from getting ASF by improving farm biosecurity. b ASF can not be prevented. c I would like to invest in farm biosecurity if I received advice on what to do. d Improved farm biosecurity improves pig health and pig growth. e Buying live pigs is a risky behaviour for contracting ASF. f Frequent selling and buying of pigs is necessary for successful pig farming. g Eating pork from pigs that have died from ASF is safe for human health. h I don’t want to eat or buy pork from pigs that have died from ASF. i Cooking kills the ASF virus. j If pork prices are lower in the neighbouring village due to them having an outbreak of ASF I will buy my pork there
