P values less than .05 specify that the odds ratio for the profile indicated a significant difference from the referent group. ^adenotes that this ratio was included for explanatory purposes only and was not included in the analysis of statistical differences between profiles. Profile 1 = low outbreak; profile 2 = high death; profile 3 = high outbreak
