Actually, Norovirus is often spread by poor hygiene of the sufferer and not necessarily the staff. If you get Noro, then your whole family will get it if you are at home. The vomiting and diarrhoea is so profuse that the bug spreads throughout the environment and atmosphere. Norovirus is often brought into hospitals by visitors (i've seen this happen).
The bathroom would need a complete clean after every toilet use 24/7. The NHS wards don't have cleaners 24/7, one cleaner can be cleaning 3 different wards and obviously can't be everywhere at once. There's nothing that can be done about the bugs in the atmosphere unfortunately. If you have norovirus you often don't realise it at first and blame the sudden diarrhoea on something you ate. it is only after a few toilet trips that patients will tell the staff that there's something wrong, by which time, it's too late as it will have already spread.
I see that the government are after employing 2,500 more hospital matrons in order to help control infections. This will clearly not work.....
It would be more appropriate to employ 5,000 cleaners/support staff. Matrons will be constantly at meetings discussing targets, they don't do any cleaning...
