Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background:
As of November 12, 2020, the mortality to incidence ratio (MIR) of COVID-19 was 5.8% in the US. We utilized a longitudinal model-based clustering system based on the disease trajectories over time. We aimed to find the so-called “vulnerable” cluster of counties where to dedicate additional resources by the US policymakers.Methods:
County-level COVID-19 cases and deaths (Mar-Nov 2020), and a set of potential risk factors were collected for 3050 U.S. counties during the 1st wave (Mar25-Jun3, 2020), 1344 counties (sunbelt region) during the 2nd wave (Jun4-Sep2, 2020), and 1055 counties (great plains) during the 3rd wave (Sep3-Nov12, 2020). We used growth mixture models to identify clusters of counties exhibiting similar COVID-19 MIR growth trajectories and risk-factors over time.Results:
We identified the so-called “more vulnerable” clusters during the 1st, 2nd and 3rd waves of COVID-19. Tuberculosis (OR=1.3-2.1-3.2), drug use disorder (OR=1.1), hepatitis (OR=13.1), HIV/AIDS (OR=2.3), cardiomyopathy and myocarditis (OR=1.3), diabetes (OR=1.2), mesothelioma (OR=9.3) were significantly associated with increased odds of being in a more vulnerable cluster. Heart complications and cancer were the main risk factors increasing the COVID-19 MIR (range 0.08%-0.52% MIR↑).Conclusion:
We identified the so-called “more vulnerable” county-clusters exhibiting the highest COVID-19 MIR trajectories, indicating that enhancing the capacity and access to healthcare resources would be key to successfully manage COVID-19 in these clusters. These findings provide insights for public health policymakers on the groups of people and locations they need to pay particular attention while managing the COVID-19 epidemic.
