Can we allow showering in the hospital?

It is very interesting to learn from The Lancet Infectious Disease, June 2003 article that virtually all outbreaks have been linked to potable water, and that showering is not a mode of transmission (except perhaps for high risk patients?). 


Showering is allowed even for high-risk patients. Highly-immunosuppressed patients and COPD (emphysema) patients should drink bottled water or boiled water that has been cooled, but this is optional. If the percent of distal water sites is  < 30%, we do not prohibit showering or drinking water for most patients even if Legionella is present in the water.
