If she wants to go out, why not ask her if she wants to go on a trail or walk in a park? I'm not saying she should congregate with other people, but you and her can go walking on a trail. That will (1.) let her get out like she wants to, and (2.) give her exercise to burn off some excess manic energy. Is that an option for you? You are less likely to get sick out on a trail than you are in an enclosed space (e.g., a store), and it it allows you to control the situation.
