I heard the anti funguls used in agriculture may be helping to build these super bugs.
As may the incessant use of disposable anti-bacterial wipes and anti-bacterial infused plastic childeren's toys. These both end up in the toxic soups of landfills and those plastic kids' toys last a loooong time giving micro-organisms plenty of chances to develope resistancy.
I don’t think it’s a superbug. The main problem seems to be misdiagnosis and inadequate cleaning. H2O2 doesn’t kill it, but chlorine bleach does.
