Exactly, and I suspect that the doctors ward rounds are a repeat performance. I'd also suspect that the cleaners would do the same, and use the same mops/buckets/water as the rest of the ward. In the 'good old days' there were isolation wards, where patients with MRSA would be nursed, and the MRSA would be fought - unfortunately bed pressures have gotten so bad, that isolation wards had to become standard wards. The hospital where I worked at the most, had 4 isolation rooms - and these were more often than not used for 'reverse isolation', when a patient with a compromised immune system must be protected from other people and their germs.
