The Burden of Long COVID: Re-Infection, Symptoms, and Barriers to Care in the Arizona CoVHORT Study

Long COVID (LC) impacts quality of life, daily functioning, and healthcare utilization. Understanding the onset and duration of symptoms, characteristics of those at higher risk, and the barriers and facilitators for healthcare access and therapeutics are key to addressing this growing disease burden. In 2024 the Arizona CoVHORT, an ongoing 6-year longitudinal study, distributed a cross-sectional LC survey to gain additional in-depth information. Of 1,543 participants, 700 reported LC symptoms lasting 2-49 months. Following their first infection, LC+ participants had a 21% higher risk for a second infection and were 3.2 times more likely to report LC symptoms after that second infection compared to LC- participants. Significant factors associated with LC included female sex (OR=2.3), Hispanic ethnicity (OR=1.5), BMI>34.5 (OR= 1.7) and >2 infections (OR=3.2), while vaccination prior to first infection decreased the odds of reporting LC by 51% (R=0.49). Qualitative analyses detailed significant barriers to care and encounters with providers who lacked knowledge to test for or treat LC symptoms. With an estimated 400 million people impacted globally by LC, it is critical to gain in-depth information from patients to improve both access and quality of care, improve messaging, and target mitigation strategies to decrease the burden over time.
