Back to the Before Times? [MicroBusiness] IEEE Microw. Mag. (IF 3.6) Pub Date : 2024-03-05 Fred Schindler
I recently returned from a long international trip, including nine flights, a couple buses, and several taxis. I wore a face mask for the first leg of the trip. I was just getting over a cold and was worried that I might still be contagious. I also didn’t want to risk catching COVID at the beginning of a long trip. I encountered very few others wearing masks—less than 5% of air travelers and only an
