"Fly infestation in Braxted ward"

I've been visiting since Friday and there seem to be an infestation of flies in the ward. This is a geriatric ward and most patients are very frail and already battling infections or semi comatose and not able to swat them away. The nurses don't seem to know where they are coming from and the more able bodied have to swat them to stop them sitting on the bare skin of patients or landing on more comatose patients even going in their mouths
