If I Want to Wear a Face Mask to Prevent COVID-19, Why Shouldn’t I?

By Betsy Todd, MPH, RN, nurse epidemiologist and AJN clinical editor. Published. March 6; updated March 12.

Times are uncertain. We don’t know how the spread of the new coronavirus will play out, or what parts of the country will be affected next. Many people continue to insist that wearing a mask in public places is “added insurance” against infection. But the reasons for NOT wearing a face mask far outweigh the purported benefit of keeping your nose and mouth covered when you’re out and about.

First, some background.

Health care workers use two main kinds of mouth and nose protection: either a regular surgical face mask, or an N95 respirator.

The purpose of a surgical mask is to prevent the wearer’s respiratory secretions from contaminating other people or surfaces. This is an example of “source control” in preventing infections. It is the reason the surgical team wears masks during operations and other invasive procedures.

N95 respirators look very much like face masks. They are designed to protect the wearer from inhaling hazardous particles (infectious agents, dust, etc.). Health care workers wear these when caring for people with COVID-19 or other serious respiratory infections.

But at least a face mask provides a physical barrier. Why shouldn’t […]

COVID-19 for Nurses: Skip the Rumors and Stick to the Basics

(Published: February 28. Editor’s note: much information in this post is now dated and the post should be read only as a response to a particular moment in time. COVID-19 is now officially a pandemic and has rapidly spread worldwide. While rumors and misinformation were, sadly, already very much in play when this was written, and the overall tone of this post was neutral and descriptive according to our knowledge at that current moment, the post only remains live for archiving purposes. Our most recent posts on the crisis can be found here.)

In the U.S. at the time of this writing, the major risk presented by the current novel coronavirus (COVID-19) is not from the disease itself but from misinformation. Rumors, misinterpretations, and conspiracy theories are being transmitted at a rate far greater than that of the coronavirus itself. While the situation is evolving rapidly and things can change quickly, our understanding of the illness has also grown in a remarkably  short period of time.

So, is this a pandemic?

In an NPR interview this week, WHO director-general Tedros Adhanom Ghebreyesus said the term is used to suggest that the spread of a new infection is out of control and doing significant damage worldwide. We are not quite there yet. COVID-19 transmission in China appears to have plateaued, and, while the virus has been detected in numerous other countries this week, several countries have also been successful in controlling the spread of COVID-19 within […]

Serious Mental Health Issues: No Room for System Errors

I knew that my patients were once without mental illness, just like my little sister Doris had been before her diagnosis 10 years before, and I always tried to picture them like that, each their own best version of themselves.

A sister’s preventable death.

In this month’s Reflections column, “No Room for Error: Reflections on My Sister,” family nurse practitioner Kelly Vaez shares the story of the unexpected death of her sister, who had been diagnosed with schizophrenia ten years earlier. It’s particularly heart-wrenching to be able to see clearly, in retrospect, the ways in which our rushed, fragmented, and mental-health-unfriendly health care system contributed to what was probably an easily preventable death.

A dentist prescribed an unusually long course of antibiotics after a routine tooth extraction. The primary care team seemed unaware of the antibiotic therapy. No one made the connection between Doris’ diarrhea and this antibiotic, a frequent cause of C.diff infection.

And finally, loperamide—a drug that should never, ever be given for diarrhea that might be caused by C. diff—was prescribed with what seems to have been minimal assessment for the cause of the diarrhea. Was this last because the patient was a young adult with schizophrenia, and […]

Recent Data on Physical Inactivity Points to a More Active Role for Nurses

“. . .more attention should be given to considering total daily sitting time and to understanding the individual, social, occupational, and community environments that contribute to [it]. Nurses have a pivotal role to play in increasing public awareness about the potential adverse effects of high-volume and prolonged uninterrupted sitting.” –“Too Much Sitting: A Newly Recognized Health Risk”

“Often when I ask patients about their lifestyle, they are quick to admit they need more exercise. As a nurse, I view such conversations as opportunities to discuss and encourage physical activity.” –“The Evolution of Physical Activity Promotion”

According to recently released data from the Centers for Disease Control and Prevention (CDC), more than 15% of U.S. adults say they don’t engage in any physical activity.

Health effects of being physically inactive.

Leading a sedentary lifestyle can lead to well-documented detrimental health effects, including an increased risk of developing cardiovascular disease, type 2 diabetes, and certain types of cancer. The World Health Organization estimates that insufficient physical activity results in 3.2 million deaths annually.

Sedentary behavior varies based on location and race/ethnicity.

Using data collected from 2015 to 2018 as part of the Behavioral Risk Factor Surveillance System, the CDC notes that inactivity levels range from an estimated 17.3%  to 47.7%, depending on […]

As Another Coronavirus Begins to Spread, Follow Reasonable Precautions and Avoid Fear-Mongering

(Editor’s note: Published January 24. The situation has considerably changed in the intervening weeks, during which the virus has rapidly spread across the globe. We obviously now know a great deal more about the dangers it presents.)

Emerging infections are part of our world—more evident these days because we have the tools and global communication networks to quickly identify them. This month, we’ve begun another crash course in the initial management of a new pathogen.

Short timeline from first cases to screening test availability.

Rumors of a concerning cluster of undiagnosed pneumonia in Wuhan, China, surfaced on social media on December 31. The patients weren’t responding to antibiotic therapy, but tests were negative for the usual viral suspects. World Health Organization staff quickly connected with Chinese health officials and testing and epidemiological investigations kicked into high gear.

Many of the infected patients had worked at a fish and live animal market in Wuhan, suggesting that the illnesses might be zoonotic (passing from animals to human) in origin. On January 7, the pathogen was identified as a new coronavirus, related (though not closely) to the coronaviruses that cause SARS and MERS. The viral genome was quickly sequenced, and on January 12, China shared the genetic sequence with the global scientific community. By […]
