it's definitely down from normal numbers of kids playing here. but those parents who allow going to playgrounds are usually OK if kids play with some distance. what I found works well is ball passing with soccer - no touch needed. badminton is also reasonable safe distance. with 'neighborhood' I meant the immediate housing project here, we have a couple of boys who are inseparable and I find the risk tolerable if those same kids play together daily. Should be simple to trace also in case the housing gets cases.
