Table 1. Time progression of the number of deaths during the outbreak.

Month	Number of dead adults	Number of dead subadults	Number of dead adults tested positive (out of)	Number of dead subadults tested positive (out of)
June	47	16	9 (9) 100%	2 (2) 100%

Progression of the tularemia outbreak based on the total number of dead adults and subadults found in the study population between June and August 2012, and the corresponding number of adults and subadults tested positive with tularemia among all tested animals (number given in brackets). The value in percent corresponds to the estimator. Note that no positive-tested mouse was found prior to June and after August (see S1 and S2 Tables for more details).
