Lack of clean water would be the number one killer
One milliliter of chlorine bleach will disinfect a gallon of water. If you have a gallon of bleach, you can disinfect 3,785 gallons of water.
Be sure you have bleach containing Sodium Hypochlorite. Some laundry bleaches are oxygen bleach. That's mainly a whitener and while it will disinfect, it doesn't kill the bugs like Chlorine.
