- MRSA screening
- disinfectant body wash

- there is a higher pressure between the doors so they cant be opened at the same time
- patients room is at a lower pressure so air wont move out
- middle is at a higher pressure so air from corridor wont move in
how can you prevent healthcare workers from developing infections
