False argument.
Autombile accidents kill children. Should we ban all vehicles?
Bathtub accidents kill children. Should we prohibit bathtubs?
Swiming accidents kill children. Should we prohibit swimming?
I could go on, but you get my point.
The responsibility for this childs healths is his and his family, not the community. Reasonable action should be taken, but forcing everyone that may come in contact with the child to bend to his needs is not resonable.
To answer your question, none.
