Experts from the COVID-19 modeling team at the University of Arizona are calling for a shelter-in-place order, mask mandate and emergency economic relief measures statewide as coronavirus metrics increase to alarming levels.

โ€œNo matter what actions are taken, Arizona will experience a hospital crisis in the coming weeks. However, if action is not immediately taken, then it risks a catastrophe on a scale of the worst natural disaster the state has ever experienced,โ€ UAโ€™s COVID-19 modeling team wrote in a memo to the Arizona Department of Health Services. โ€œIt would be akin to facing a major forest fire without evacuation orders.โ€

Dr. Joe Gerald, a professor at UA who creates weekly coronavirus epidemiology reports based on ADHS data, also called for further COVID-19 mitigation tactics as his latest report shows an alarming spread of the virus throughout the state.

โ€œArizona is experiencing a public health crisis where access to critical care services is limited due to shortages of space, personnel, and critical supplies. If not addressed within the next 2-3 weeks, this crisis will evolve into a humanitarian crisis leading to hundreds of preventable deaths,โ€ Gerald wrote in his latest report. โ€œAt this point, only shelter-in-place restrictions are certain to quickly and sufficiently curtail viral transmission.โ€

According to Gerald’s latest update, Arizona likely passed concerning thresholds of 30,000 COVID-19 cases per week and 4,000 cases per day this week.

His report says Arizona’s COVID-19 test positivity reached 17% the past week, providing โ€œadditional evidence that viral transmission continues to increase despite the uncertainty surrounding actual case counts.โ€

On Friday, Nov. 27, 28% of hospital ward beds were filled by COVID-19 patients, a 24% increase from the week prior. Of the stateโ€™s ICU beds, 32% were occupied by coronavirus patients, a 27% increase from last week, according to Geraldโ€™s report.

Members of the COVID-19 modeling team at UA said Arizona State Universityโ€™s COVID-19 projections predict by early December, hospitalizations will exceed current ICU and general ward capacity throughout the state.

By late December, the ASU COVID-19 modeling team predicts hospitalizations will exceed their total capacity, causing โ€œno additional availability to provide care for routine, urgent, or emergent non-COVID care,โ€ according to the UA modeling teamโ€™s memo.

Gerald wrote in his report that if total hospital capacity is reached, โ€œit would represent a humanitarian crisis of unparalleled proportion and would be accompanied by hundreds if not thousands of preventable deaths.โ€

Gerald says the stateโ€™s โ€œhospitalsโ€™ safety margin continues to erodeโ€ not only because of a surge in COVID-19 cases but due to other non-coronavirus related procedures and illnesses hospitals are handling.

โ€œWhile occupancy data suggest Arizona hospitals should be under greater strain, the fact that admissions are dispersed across multiple units, not just COVID-specific units, means the workload is more evenly distributed across physicians, nurses and other health professionals,โ€ Gerald said in his report. โ€œAs COVID-19 admissions continue to increase, this advantage will be lost.โ€

Geraldโ€™s data shows 3,660 COVID-19 cases among Pima County residents for the week ending Nov. 22, a 39% increase from the previous week, setting a record for the highest weekly case count in the county.

โ€œIn this regard, Arizona should reinstate its shelter-in-place order for the post-Thanksgiving โ€“ Christmas period,โ€ Gerald wrote in his report. โ€œWhile more targeted restrictions could have slowed transmission if implemented weeks ago, the potential consequences of an outbreak of this size and trajectory are too dire to rely on half-measures now.โ€

UAโ€™s COVID-19 modeling team is calling for a three-week shelter-in-place order from Dec. 1-Dec. 22, an enforceable statewide mask mandate and emergency relief measures for small businesses and other entities affected by a potential stay-at-home ordinance.

The group is also asking for county and municipal leaders to be given the authority to enact local shelter-in-place mandates.

Gerald also called for further statewide action against the spread of the virus given the dire implications of its continued spread.

โ€œAcknowledging that a shelter-in-place order is unlikely, counties should be granted additional authority to establish and enforce alternative COVID-19 mitigation policies,โ€ Gerald said in his report. โ€œThe only unacceptable course is inaction. Without intervention, we are on track to experience a major humanitarian crisis during the Christmas โ€“ New Year holiday season.โ€
