Handwashing
In elementary school children (P), how does handwashing for a duration of 30 seconds or more (I) compared to handwashing for less than 20 seconds (C) affect the reduction of communicable disease spread (O) over a period of six months (T)?
Sample Solution
Hand hygiene is a key component of good hygiene practice in the home and community and can produce significant benefits in terms of reducing the incidence of infection, most particularly gastrointestinal infections but also respiratory tract and skin infections. Decontamination of hands can be carried out either by handwashing with soap or by use of waterless hand sanitizers, which reduce contamination on hands by removal or by killing the organisms in situ. The health impact of hand hygiene within a given community can be increased by using products and procedures, either alone or in sequence, that maximize the log reduction of both bacteria and viruses on hands.
