The complete model is described in the Appendix S1. Figure S1 Confirmed imported (red) and domestic (blue) cases in Germany by date of onset of symptoms (A Figure S3 Delay of epidemic curve. The ''most likely'' Ro of 1.58 from the study of Fraser et al. (Science, 2007) was used and case detection rates of symptomatic cases were set to 10% and 30%, respectively. Ro is assumed to be 1.58, and each day five cases were imported. The household and non-household contacts of the first 500 detected cases were treated with a combination of case-based measures that include contact tracing, quarantine, and post-exposure prophylaxis (CCM1); and the household contacts of the next 10,000 cases were managed with strategy CCM2, which includes only preventive measures in the household of the cases.  European Hedgehogs as Hosts for Borrelia spp., Germany  . Members of the B. burgdorferi s. l. group are the most common vectorborne pathogens of humans in central Europe (3) . The role of hedgehogs as hosts for these pathogens is, therefore, of considerable epidemiologic interest. Hedgehogs are a common synanthropic species that live in urban, suburban, and rural environments (4) and are known to carry not only the hedgehog tick, Ixodes hexagonus, but also the most common European tick, I. ricinus (2, 5) . Both of these ticks are known vectors of B. burgdorferi s. l. and tickborne encephalitis virus; I. ricinus is the most important vector of both throughout Europe (1, 5) . To date, however, only limited information has been available on the role of the hedgehog as a host or reservoir for B. burgdorferi s. l. in Germany.
