Figure 1. Geographic origin of 263 Eurasian lynx (Lynx lynx) collected in Sweden during 1995–1999 and tested for orthopoxvirus (OPV)–specific DNA (open circles). OPV DNA was amplified by PCR from 24 animals (9%; red circles). Light blue areas represent sparsely populated (<5 inhabitants/km2) mountainous counties; medium blue areas represent more densely populated counties (10–41 inhabitants/km2) farther south; and dark blue areas represent counties with the highest human population densities (>50 inhabitants/km2).
