thank you all, you guys have been really wondeful

Hi!

We came to the conclusion with a brief literature review that the evidence for length of handwashing is inconclusive in community settings. This is mentioned in the intro of our paper, here: www.sciencedirect.com/science/article/pii/S0196655316307933. We also found that within the cohort we studied (same paper), natural variation observed for length did not influence microbiological effectiveness.

Maybe that information is also helpful along with the previously mentioned documents.

I'm attaching some publications here. These may, or may, not give you the exact information you need, but gives a wealth of information.

Enjoy!

hi all
am looking for scientific evidence of 2 minutes hand wash, 1.5 sec hand wash , 1 min hand wash , 30 sec hand wash in a community setting. similarly what about hand washing in airplanes? what about hand washing where water is scarce ? how long is long enough and the scientific evidence. am kind of desperate here any inputs will be highly appreciated.
thank you
