It depends on your state. Most states have no guidelines about camps. For ACA, rules depend on where your camp is located and how far you are from medical attention. For Girl Scouts/Safetywise, it depends on how many people; you would almost certainly just need someone with "advanced first aid", usually First Responder or something of the sort. The Girl Scout rules are likely going to be the strictest; you can check with your council's event-planning guidelines.
