This may be due to increasing the flow of contaminated air over the hands.
An investigation into spread of SARS presented at the California Indoor Air Quality conference this year demonstrated massive "aerosolization" of virus particles associated with toilet flushing… so the air in the washrooms will be full of virus. If you then concentrate that by directing more air over the hands it seems logical that this will increase bugs on the hands?
