Caught an article in their local press about a grade school school in Connecticut experiencing an outbreak of a viral infection; the article touted the school district's bringing in the janitorial contractor to do a one shot sanitizing of touch-points - desk tops, door jambs, and so on.
This sounds good at first. But I noticed, further down the article, that kids will be infectious before showing symptoms. So, we sanitize the school tonight, and a kid (or several) comes to school tomorrow, feeling and looking healthy, and touching things. The school stayed sanitized from when the janitor finished last night to when the first child touched a doorknob this morning.
A couple of months ago, a long time client - a small architecture office, that we clean just once per week - called about several of their staff being sick. They asked us to temporarily up service to nightly, with an emphasis on sanitizing touch-points; they also had the wisdom to ask what else could be done. I set them up with boxes of sanitizing wipes, for use by their staff all day long, and pointed them in the direction of a pathogen killing lotion that we issue to our nightly cleaning crews, claimed to be effective for some 4 hours after applying to ones hands (thus protecting the user, and anything or anyone he touched).
In passing, our normal protocol on cleaning and sanitizing touch-points involves Diversey AlphaHP, a hydrogen peroxide cleaner-sanitizer with a 30- to 60-second kill time, applied with a microfiber cloth. We did the same for the intensive regime, but followed it with a misting of Diversey's Virex, a quat based hospital grade disinfectant. I needs 10 minutes dwell time, wet, which is hard to achieve on general office touch-points, so I did not claim full disinfection to the client, but it doubtless gave the already quite effective HP a good boost.
My client's (and my) response, while a bit more costly, seems an approach much more likely to work. And it's not likely to be more costly than having more staff out sick or, worse, sick at work.
