I just did a partial search focusing on #HandWashing in the #community setting.
First thing to note is these articles are mostly indexed under #HandHygiene.
Next thing is there are many hits on various aspects on nursing and hospitals.
Filtering for the above I found several articles showing benefit, typical results…
"Meta-analyses to generate pooled rate ratios across interventions (N=30 studies). Improvements in hand hygiene resulted in reductions in gastrointestinal illness of 31% (95% confidence intervals [CI]=19%, 42%) and reductions in respiratory illness of 21% (95% CI=5%, 34%). The most beneficial intervention was hand-hygiene education with use of #nonantibacterial #soap. Use of antibacterial soap showed little added benefit compared with use of nonantibacterial soap. Hand hygiene is clearly effective against gastrointestinal and, to a lesser extent, respiratory infections." (2008)
