Face masks do NOT protect the wearer from coronavirus but will stop them from infecting other people: True or False?


  • More than 6,000 adults and split them into two groups: one wearing masks in public and one control group that did not
  • After one month, 1.8% of the people wearing masks had been infected with the virus and 2.1% in the unmasked group had tested positive for COVID-19
  • The lack of statistical significance suggests that there may be limited protection against coronavirus infection for the wearer
  • Researchers say people should keep wearing them because the wearer can prevent others from being infected

Admin – The above article was extracted from the peer-reviewed paper. Effectiveness of Adding a Mask Recommendation to Other Public Health Measures to Prevent SARS-CoV-2 Infection in Danish Mask Wearers. I don’t try to suppress articles that I have concerns about, but, as in this case, I often trace back to the original published report. I didn’t feel the paper had flaws but the authors clearly stated its limitations:

“Limitations: Inconclusive results, missing data, variable adherence, patient-reported findings on home tests, no blinding, and no assessment of whether masks could decrease disease transmission from mask wearers to others.”

Unfortunately, the paper did not consider a secondary infection route the eyes. Here, infections may occur by touching one’s eye with contaminated hands or direct droplet exposure. SARS-CoV-2 on the ocular surface: is it truly a novel transmission route?

Excerpts from Other Studies:


“This study found that the proportion of inpatients with COVID-19 who wear eyeglasses for extended daily periods was lower than that of the general population, suggesting that daily wear of eyeglasses is associated with less susceptibility to COVID-19 infection.”


Wang et al74 recently reported that 138 hospitalized SARS-COV-2-infected pneumonia cases had a hospital-associated transmission rate of 41%, among whom 70% were healthcare professionals. The main risk factor for the nosocomial infection of medical staff members who provided nursing care to the intubated patients with SARS was whether they wore protective goggles (1% of the clinicians wearing eye protection were infected versus 8% of the clinicians who did not).75
