Figure 4. A) Cluster site for tularemia transmission at Oset/Rynningeviken nature reserve in Örebro, Sweden, with 83 patient reports. Twenty-seven Francisella tularensis isolates were recovered from these patients. B) Cluster site for tularemia transmission at Lake Lången, Örebro, Sweden, with 17 patient reports. Nine F. tularensis isolates were recovered from these patients. Place of disease transmission were reported to be certain (circle), probable (square), or possible (diamond); patient residency (triangle) was used if no such data was available. Genetic groups are indicated by color: yellow (1a), green (1b), blue (1d), or purple (2); white indicates no F. tularensis culture.
