Design outcomes

Primary

MeasureTime frame
To determine the antimicrobial effectiveness of various test products for use as Health Care Personnel Handwashes using indicator microorganism Serratia marcescens for hand contaminations. Between 8 to 24 volunteers is tested using each test configuration over eleven consecutive hand contaminations, the first followed by baseline sample and the remaining ten by product applications, with microbial samples taken after product applications one, three, seven, and ten.Timepoint: Critical indices are a two log10 reduction at wash 1 and a three log10 reduction at wash 10.
