45 fatalities increases to 107 fatalities
107-45=62
62/45=1.3777...=137.777... % increase or 137.777...% more deadly
if there were 45 fatalities and it increased to 90 fatalities that would be 100% more deadly
if there were 45 fatalities and it increased to 135 fatalities that would be 200% more deadly
