Changes to Mask Guidelines at the University of Arizona

On February 25th, 2022 the Centers for Disease Control and Prevention updated its


COVID-19 guidelines and stated that masks may no longer be necessary in U.S counties


with medium to low transmission rates. This is guidance that the University of Arizona is


taking to heart. On March 17, 2022, the University of Arizona announced that masks will be


recommended, but no longer necessary in indoor spaces as of Monday, March 21st


(University of Arizona). This does not extend onto CatTran shuttles, however, which are


following Transportation Security Administration directives. At the time of the briefing, 80.7%


of Pima County residents had received at least one dose of a COVID-19 vaccine.


It's important to be wary of what metrics are being considered when governing bodies, like


the CDC, make these recommendations, especially since these recommendations may be in


a constant state of flux. For example, an early CDC recommendation advised masking in


schools no matter the level of COVID 19 impact (CDC Transcript). Earlier this month,


however, the CDC began to recommend masking in school only within communities with a


"high" level of COVID-19.

The CDC measures these covid risk levels using the following three metrics: new


COVID-19 hospital admission per 100,000 people in the past 7 days, the percent of staffed


inpatient beds occupied by COVID-19 patients, and the total new COVID-19 cases per


100,000 population in the past 7 days (CDC.gov). Pima is currently at a low level of COVID


risk, and is seeing 77.92 cases per 100K people, 5.4 hospital admissions per 100k people,


and 3% of occupied hospital beds as of March 17, 2022 according to data calculated from


the prior week.


With these changes in risk levels, administrators across the United States have been


reconsidering their mask mandates, but it may be a premature change. Masks work by


blocking the particles that transmit COVID-19. The virus is 0.1 µm in diameter and can


transfer on droplets and aerosols, most of which are 1-10 µm in diameter. When a person


breathes, talks, sneezes, or coughs, particles are exhaled either as visible droplets or


microscopic aerosols. Viruses, such as COVID-19, can catch on to those particles and


spread. Droplets are pulled to the ground by gravity fairly quickly, but can spread if they land


nearby on a person's eyes, nose or mouth. Aerosols can stay in the air for minutes to hours


depending on the ventilation of the room (Nature.com).


Scientists, such as Mercedes Carnethon, professor of epidemiology and vice chair of


the Department of Preventive Medicine at Northwestern University, say that "it's premature in


many regions of the country to consider lifting these mask mandates… certain conditions


need to be met in order for those lifting of mask mandates to make sense and continue to


protect our school populations." In addition, an open letter signed by around 400 different


health professionals urged elected officials to reevaluate the end of school mask mandates


(Medium.com).


With the changes in the mask mandate at the University of Arizona, President Robbins


stated, "I encourage individuals who are at higher risk of serious illness or who live with


people in high-risk groups to continue to wear a surgical mask or higher-grade mask around


others to limit their exposure to the virus." While well-intentioned, this statement may not help


properly protect students and faculty members who are at higher risk of COVID-19,


especially since one-way masking is much less effective than when all parties are masked


(Slate.com). Members of the University of Arizona who are at higher risk of illness can


contact the Disability Resource Center (Disability Resource Center) for more information.
