I don't think medical professionals get adequate infection control training. My observation is that many of them know diddly squat about cross contamination. In California, dental professionals must take an infection control course every two years for relicensure. Of course, working in saliva, blood and other nastiness with high speed cutting tools generating all kinds of aerosolized ugliness forces dental professionals to look at the dental environment and the health and safety of themselves and their patients.
Wearing PPE and then exposing oneself to pathogens by improper removal of PPE is crazy and self-defeating. People definitely need training in this area.
