The COVID-19 pandemic has made all of us painfully aware of the presence of harmful pathogens aka invisible menaces. Disinfection which is part of the cure we seek, is far from a perfect science. As my microbiologist friend would say "do we want to get rid of all the bugs Kurt?" When I started killing pathogens with my inventions, I thought yes. Now, the answer is absolutely no. While striking the right balance seems to be elusive we should not kid ourselves that some of the solutions being offered are far from the high effectiveness claims being casually tossed around. And we should be vigilant to learn more about disinfection. We are looking for a sweet spot. And now we have to worry that we are not safe even when people claim to protect us with devices and services.
The attached photo was part of a presentation at a recent ultraviolet light conference held 8th and 9th of December 2020. We are still a ways from getting it right or even defining right in some cases. I apologize for offering no solutions today, just food for thought.
