I have experience in hospitals that are qualified to treat radiologically contaminated patients from nuclear facilities.
Without exception, these facilities have an isolated “carport” area established to receive the ambulance, and a short distance into a room with contamination controls and ability to decontaminate surfaces. You think Federal funding could have matched what podunk mid-level hospitals have been able to cobble together.
As was seen in this picture, walking across 30 yards of gravel from ambulance to treatment is hardly the way to contain, control, minimize, or later decontaminate any viral “contamination” that could be present on ambulance riders.
God help us all, this is sure to spread due to poorly planned or implemented contamination control.
