This question has been asked of us following this report: Temperature Screening Is Ineffective, Says US, UK, Canada, Israel, And Ireland Health Leaders. Basically, if these health leaders say it is ineffective, what should users do? what does IPVM recommend?
Let me start with a story. About a month ago, someone emailed me over and over about some crowd fever screening offering that showed detecting fevers off the sides and backs of people's heads (like Convergint but different). The person kept on badgering me, saying that it would be impractical to screen people one by one and was frustrated that I would not give credence further into a system claiming to do that.
I get it - You want some way to detect fevers as people randomly walk around, outdoors, in the rain, wearing face shields, etc. It does not work. Our testing shows that. The FDA guidelines show that. IEC standards show that.
If you want to do right (and in the US, that means following FDA guidelines), that means people removing eyeglasses and hats, and scanning people one at time, indoors, acclimated to a climate-controlled environment. Then people say well that's not convenient or people are going to be annoyed to wait, etc.
What do you tell such people? Seriously?
And then you have the issue with so many Coronavirus infected people being asymptomatic or presymptomatic.
As the health leaders, like Dr. Fauci, say, it strikes me as more prudent to ask questions, reminding and encouraging people who don’t feel well to stay home, unless you really want to pay for a real thermography system and set it up in a proper way (which is both expensive and time-consuming for those being screened).
Of course, guys are making record profits selling these systems so I understand the motivation and temptation here, despite the evidence and issues to the contrary.
Here's a poll:
