Sounds to me you are doing what you can. My guess is they are probably first time moms and have not experienced putting a child in daycare before. I always knew that my kids would start getting sick when they started a new daycare and at the beginning of every school year. Unfortunately you are right parents send their kids to daycare and school sick. They a lot of times feel they don't have a choice but that is not fair to you. Just keep doing what you are going. Too bad there is not something to make every kid and parent walk through when they come in that would sanitize them and anything that comes in. Good luck!
