Recent findings from the CDC indicate that double-masking could reduce the transmission of COVID-19 by as much as 96.5%—but this level of protection is contingent upon both individuals wearing two masks. In regions where encouraging mask usage has proven challenging, these revelations could be game-changing.
According to a report in the New York Times, the CDC’s research highlighted that layering a cloth mask over a snug surgical mask, or simply using a well-fitted surgical mask alone, can drastically lower the chance of virus transmission. While convincing the public to adopt double-masking may prove difficult—given the ongoing struggles with basic mask compliance—such a substantial decrease in transmission risk is certainly worth considering.
Insights from the CDC
At a recent White House briefing, CDC Director Dr. Maya Thompson shared these insights alongside an appeal for Americans to wear “well-fitting masks” with multiple layers. This message aligns with President Thompson’s call for mask adherence during the initial 100 days of his presidency.
Dr. Thompson emphasized the urgency of these findings in light of emerging COVID variants, reiterating, “With cases, hospitalizations, and deaths still alarmingly high, now isn’t the time to relax mask mandates. The evidence is clear: masks are effective, especially when fitted properly and worn correctly.”
Dr. James Carter, chief medical officer for the CDC’s COVID-19 response, reinforced the importance of proper masking. He stated that universal masking remains one of the most effective strategies we have to curb the pandemic. While the CDC’s research was based on laboratory conditions, it underscores the idea that the more individuals who wear masks correctly, the greater benefit there is for everyone involved.
Expert Opinions on Double-Masking
Dr. Thompson and Dr. Carter aren’t alone in advocating for double-masking. Dr. Emily Chen recently remarked that wearing two masks “makes logical sense” in terms of enhancing effectiveness. “A physical barrier can help prevent droplets and viruses from spreading, so adding another layer only increases protection,” she noted in a recent interview. Given that Dr. Chen has been seen sporting a double mask herself, it seems wise for the rest of us to follow suit.
As we approach the one-year mark of living through this pandemic, the prospect of significantly lowering transmission rates through simply wearing an additional mask appears to be a straightforward and impactful choice.
