Unfazed by data, scientific research, or common sense, the maskaholics are back. In response to an uptick in Covid cases, they’ve begun reinstating mask mandates. So far, it’s just a few places—a college in Atlanta, a Hollywood studio, two hospitals in Syracuse—but the mainstream media and their favorite “experts” are working hard to scare the rest of us into masking up yet again.

Never mind that at least 97 percent of Americans have Covid antibodies in their blood as a result of infection, vaccination, or both. Never mind that actual experts—the ones who studied the scientific literature before 2020 and drew up plans for a pandemic—advised against masking the public. Never mind that their advice has been further bolstered during the pandemic by randomized clinical trials and rigorous observational studies failing to find an effect of masks and mask mandates. Scientific evidence cannot overcome the maskaholics’ faith.

It’s tempting to compare them with the villagers in Cambodia who erected scarecrows in front of their huts to ward off the coronavirus—but that’s not fair to the villagers. Their Ting Mong, as the magic scarecrows are called, at least didn’t hurt any of their neighbors. The mask mandates imposed harms on the public that were well known before Covid, which was why occupational-safety regulations limited workers’ mask usage. Dozens of studies had demonstrated “Mask-Induced Exhaustion Syndrome,” whose symptoms include an increase of carbon dioxide in the blood, difficulty breathing, dizziness, drowsiness, headache, and diminished ability to concentrate and think. It was no surprise during the pandemic when adverse effects of masks were reported in a study of health-care workers in New York City. More than 70 percent of the workers said that prolonged mask-wearing gave them headaches, and nearly a quarter blamed it for “impaired cognition.”
