The front porch is the "decon room," but that is only for those being deconned. The high-exposure-risk family member goes through a separate door into the negative-pressure suite, which has its own shower for decon after shoes and outer clothing has been removed at the exterior entry door. To go on a family walk around the neighborhood, that person comes out of the separate door, walks, then goes back into the negative-pressure suite through the separate door. Food is placed outside the ceiling-to-floor polyethylene barrier with overlapping flaps at the interior entrance to the negative-pressure suite to be brought into the suite once others have cleared from the area. All air being drawn from the negative-pressure suite is HEPA filtered before being exhausted outdoors.
