We have had this discussion to the point of nausea, right? Sorry, I’m back again to add to your angst! I recently visited an acute care facility where a family member was being cared for. I proudly donned my KN95 mask, used hand sanitizer at the entrance and went to the screening desk for a temperature check (yes, this added …

Mask UP!

Angie SzumlinskiNews

Disposable medical procedure masks are commonly worn in health care and public settings during the COVID-19 pandemic. The Filtered Filtration Efficiency (FFE) for procedure masks is generally below that of high-efficiency N95 respirators certified by the US National Institute for Occupational Safety and Health and foreign-sourced equivalents (i.e., KN95). However, many procedure masks available to the public are constructed with …

Double Masking

Angie SzumlinskiNews

Although global vaccination efforts against SARS-CoV-2 are underway, the public is urged to continue using face masks as a primary intervention to control transmission. Recently, US public health officials have also encouraged doubling masks as a strategy to counter elevated transmission associated with infectious SARS-CoV-2 variants. US Centers for Disease Control and Prevention investigators reported that doubling masks increased effectiveness, but their …

Oh Boy – Masks and Dining – Again

Angie SzumlinskiHealth, Studies

Mask mandates were associated with statistically decreases in county-level daily COVID-19 case and death growth rates within 20 days of implementation. Allowing on-premises restaurant dining was associated with increases in county-level case and death growth rates within 41-80 days after reopening. State mask mandates and prohibiting on-premises dining at restaurants help limit potential exposure to SARS-CoV-2, reducing community transmission of …

Facemask Repurposing

Angie SzumlinskiStudies

The coronavirus (COVID-19) pandemic has not only created a global health crisis, but it is also now threatening the environment. A multidisciplinary collaborative approach is required to fight against the pandemic and reduce the environmental risks associated with the disposal of used personal protective equipment (PPE).

Counterfeit N95 face masks are on the rise and according to the Centers for Disease Control and Prevention, there is no guarantee they provide the same protection as masks approved by the National Institute for Occupational Safety and Health (NIOSH), the agency in the United States that regulates filtering facepiece respirators. In an article published in Medscape, a clear sign …

Double Mask?

Angie SzumlinskiHealth, Studies

The CDC conducted experiments to assess two ways of improving the fit of medical procedure masks: fitting a cloth mask over a medical procedure mask, and knotting the ear loops of a medical procedure mask, and then tucking in and flattening the extra material close to the face. Each modification substantially improved source control and reduced wearer exposure. “Double masking” …

Mask Times Two: The Question

Angie SzumlinskiNews

They say two heads are better than one; can the same be said for facemasks? The answer is yes, according to Dr. Anthony Fauci, the nation’s top infectious disease expert. A study published in the peer-reviewed journal “Matter” in July found that wearing two masks could increase protection from virus particles by 50% up to 75%. It not only added …

Mask Filtration Efficiency

Angie SzumlinskiHealth, Studies

In March 2020, the soaring number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections resulted in an unprecedented shortage of personal protective equipment (PPE) for clinicians and essential health care workers. The shortage was most profound among N95 respirators, named for their ability to filter 95% or more of tiny 0.3 µm particles, and are considered the mainstay of …
