# Surgical Masks Outperform Cloth Masks in COVID-19 Prevention
Written on
Chapter 1: The Current State of COVID-19
Recent reports indicate a decline in COVID-19 cases across the nation. However, this trend comes with a warning: while overall numbers are decreasing, certain northern states still report high infection rates. As of October 6, 2021, the U.S. recorded an average of 101,262 new cases and 1,810 fatalities, according to the New York Times COVID-19 tracker. It’s crucial not to relax safety measures such as mask-wearing and social distancing.
The combination of widespread vaccination and mask usage has contributed to lowering infection rates. Yet, nearly 68 million people in the U.S. remain unvaccinated. A disparity in vaccination rates, particularly between southern and midwestern states compared to others, may hinder national progress. Among adolescents aged 12-17, only 47% are fully vaccinated nationwide, with several southern states lagging behind. Analysis from CNN highlights that states like Alabama, Georgia, Louisiana, Mississippi, South Carolina, and Tennessee have less than one-third of eligible youths fully vaccinated. Many of these states are governed by Republicans who oppose mask and vaccine mandates.
Studies underscore the efficacy of masks.
Section 1.1: Evidence from Bangladesh
One of the most comprehensive studies on mask effectiveness was conducted in Bangladesh, involving 340,000 individuals across 600 villages. Researchers from Stanford Medicine and Yale University discovered that a 30% increase in mask use resulted in a 10% reduction in COVID-19 transmission. Published on September 1, 2021, this study confirmed that surgical masks are significantly more effective than cloth masks at lowering COVID-19 rates.
A separate investigation by the CDC, published on February 19, 2021, showed that adjusting surgical masks—by knotting the ear loops and tucking in the sides—enhanced their effectiveness, reducing exposure by nearly 65%. Additionally, wearing a cloth mask over a surgical mask, a practice known as double masking, decreased exposure to aerosolized particles by 83%. A Tokyo study from October 21, 2020, found that while cloth masks offered limited protection (17-27%), surgical masks provided up to 50% protection, and N95 masks blocked over 90%.
Section 1.2: Understanding Different Mask Types
Cloth Masks: Generally regarded as the least effective, their efficacy varies based on the material and number of layers.
Surgical Masks: Disposable and efficient at filtering large airborne particles, surgical masks are the most effective and cost-efficient option available.
Cloth Masks with Filter Pockets: These masks allow for the insertion of filters, providing extra protection and can be reused after washing.
N95/KN95 Masks: These respirators fit closely to the face and filter out 95% of small particles, offering superior protection compared to surgical or cloth masks.
Initially, surgical and N95 masks were scarce, prompting many to create cloth masks. Today, various affordable options are widely accessible, particularly online. Given the new evidence, relying solely on cloth masks is not advisable. For those interested in style, wearing a cloth mask over a surgical mask is a viable option.
Chapter 2: The Impact of Vaccinations
Vaccination efforts have proven to save lives, reduce hospital admissions, and lower mortality rates. A report from the U.S. Department of Health and Human Services estimates that vaccinations prevented approximately 265,000 infections, 107,000 hospitalizations, and 39,000 deaths among Medicare beneficiaries in the first five months of 2021. The same report indicated that a 10% rise in vaccination rates correlated with an 11-12% decrease in hospitalizations and deaths.
A research paper published in The Lancet on October 7, 2021, compared hospitalization and death rates due to COVID-19 in New England, where 74% of adults are vaccinated, to states like Florida and Texas, with only 59.5% and 55.8% fully vaccinated, respectively. The study concluded that higher vaccination rates in these states could have prevented over 70,000 hospitalizations and 4,700 deaths by the end of July.
Section 2.1: The Role of Mask Mandates
Studies conducted by researchers from Brigham and Women’s Hospital and Harvard Medical School indicate that mask mandates significantly reduced new COVID-19 cases (14%), deaths (13%), and hospital admissions (7%) across all 50 states and the District of Columbia, covering 77% of the population before vaccines were available.
Who Should Wear Masks and When?
Everyone should wear a mask indoors when unvaccinated individuals are present. In crowded areas where vaccination status is uncertain, opting for a high-quality mask, such as an N95 or KN95, is advisable. Even if you are the only person masked, your mask can still filter out airborne viral particles.
Unvaccinated individuals need to wear masks, as they possess the least protection against COVID-19, making masks the next best defense. Teachers, staff, and school bus drivers should also wear masks to protect children, many of whom are not yet eligible for vaccination. Additionally, all children attending school should be masked, as even vaccinated children might be around asymptomatic carriers.
Finally, adults who interact with young children—parents, grandparents, and relatives—should wear masks to reduce the risk of transmitting the virus to unvaccinated kids.
While mask-wearing may not be a permanent requirement, using them in high-risk areas now can lessen future needs and prevent numerous fatalities. Personally, I continue to wear a mask, as it also provides protection against common colds, flu, and allergens.
My Advice: Keep Wearing Your Mask
Vaccines and masks remain the most reliable defenses against COVID-19 and its variants.
