Masks Are a Distraction From the Pandemic Reality

Viruses inevitably spread, and authorities have oversold face coverings as a preventive measure

By Joseph A. Ladapo. He is an associate professor at UCLA’s David Geffen School of Medicine. Excerpts:

"A hallmark of Covid-19 pandemic policy has been the failure of political leaders and health officials to anticipate the unintended consequences of their actions. This tendency has haunted many decisions, from lockdowns that triggered enormous unemployment and increased alcohol and drug abuse, to school closures that are widening educational disparities between rich and poor families. Mask mandates may also have unintended consequences that outweigh the benefits."

"Several randomized trials of community or household masking have been completed. Most have shown that wearing a mask has little or no effect on respiratory virus transmission, according to a review published earlier this year in Emerging Infectious Diseases, the Centers for Disease Control and Prevention’s journal."

"presymptomatic spread of respiratory viruses isn’t a novel phenomenon in public health. Asymptomatic cases of influenza occur in up to a third of patients, according to a 2016 report in Emerging Infectious Diseases, and even more patients had mild cases that are never diagnosed. Asymptomatic or mild cases appear to contribute more to Covid-19 transmission, but this happens in flu cases, too, though no one has called for mask mandates during flu season."

"Policy makers and the media point to low-quality evidence, such as a study of Covid-19 positive hairstylists in Missouri or a Georgia summer camp with an outbreak. These anecdotes, while valuable, tell us nothing about the experience of other hairdressers or other summer camps that adopted similar or different masking practices."

"the highest-quality evidence so far is studies like the one published in June in Health Affairs, which found that U.S. states instituting mask mandates had a 2% reduction in growth rates of Covid-19 compared with states without these mandates. Because respiratory virus spread is exponential, modest reductions can translate into large differences over time. But these shifts in trajectory are distinct from the notion that mandating masks will bring the pandemic to an end."

"community mask mandates have—at most—a small effect on the course of the pandemic."

"Claims that low mask compliance is responsible for rising case counts are also not supported by Gallup data, which show that the percentage of Americans reporting wearing masks has been high and relatively stable since June."

"One contact-tracing study identified only a single incident of outdoor transmission among 318 outbreaks."

"mask mandates have the unintended consequence of delaying public acceptance of the unavoidable truth. In countries with active community transmission and no herd immunity, nothing short of inhumane lockdowns can stop the spread of Covid-19, so the most sensible and sustainable path forward is to learn to live with the virus."

"treating patients early in outpatient settings can be effective, as outlined in a recent American Journal of Medicine paper, but these treatments are underused."
