As stores scramble to keep their employees safe from COVID-19, some are considering taking customers' temperatures before they enter the store - a measure Logan says would be challenging and risky to implement.
Safety measures in big retailers and grocery stores have increased to include plexiglass at registers, social distancing procedures, and one-way aisles to reduce crowding as the crisis has progressed. Logan points out that grocery chains have been reluctant to take actions that risk scaring shoppers, even if they make sense from a public health perspective, and checking temperatures may be too logistically challenging.
"Checking the temperatures of shoppers would help protect both grocery workers and shoppers," he said, "but it's likely that not all shoppers would agree to this and it would require a major effort on the part of the chains when you consider the huge surge in numbers many of them are experiencing."
