Factors affecting whether somebody has "heard about the fox tapeworm". Percentages of interviewees in Czech Republic (CZ), France (FR), Germany (DE) and Switzerland (CH) that know the fox tapeworm (error lines = 95% confidence intervals). (A) AGE: age of interviewee. (B) STATUS EM: rough estimate of E. multilocularis prevalence in foxes in the region where the interviewees live: 'low/not detected' = prevalence is low or the parasite has yet not been detected, 'middle' = middle prevalence, 'high' = high relative prevalence (in Switzerland no low endemic region was identified). (C) COMMUNITY: '< 5'000' = the interviewee lives in a community with less than 5'000 inhabitants, '5–50/90'000' = community with 5 to 50 thousands inhabitants (FR, CH, DE) or in a community with 5 to 90 thousands inhabitants (CZ), '> 50/90'000' = community with more than 50 thousands (FR, CH, DE) or 90 thousands (CZ) inhabitants. (D) ATTITUDE: 'negative' = interviewees think it is very/rather bad that foxes live in urban areas, 'positive' = interviewees think it is very/rather good that foxes live in urban areas, 'don't know' = interviewees do no have an attitude towards urban foxes.
