where there are kids as young as a few months old that are sick. anyone that says you don't have worry about it if you are a young, healthy person, you do need to think about it and that's the reason why the recommendations are for kids under 12 that they avoid being in places where they might get infected which means recommendations of mask wearing in schools and at home. parents of unvaccinated kids should be thoughtful about this and recommendation is to wear masks as well. i know that's uncomfortable. i know it seems weird, but it's the best way to protect your kids. >> i want to fully understand if this is about protecting the kids from delta or an issue of worrying that the kids could pass it to other people? is delta making kids more sick? are they getting sicker than they were? any evidence of that from the previous variants?
