Dr. Ray Baker of Cincinnati Children Hospital does not go that far, but he is doing his best to get parents into a frenzy. What he is concerned about and has noticed is that kids are doing stupid things or react hypersensitively towards cicadas. They are either scared by the bugs and injured themselves running away, or they are injured trying to crush the bugs.
Cicadas are not going to kill anyone directly. If you are unlucky enough to get one in your car and can't handle the buzzing I guess you crash and die. If you try to eat the bugs, make sure you chew them well, we don't want you to choke on them either.
