My daughter and son in law went to a bible camp a few years ago for a week long event. A gal there had whooping cough and thought she would be healed and with faith not give it to others. My kids came home with it and all the family got it. Like 8 kids and mom and dad. If your sick stay home I would keep my kids from school if they were sick so not to pass it to others. Common sense no matter what because there are to many people in this world that have health problems an we all need to think about them.
