Previous research found increased COVID-19 spread associated with politics and on-demand testing but not in the same study. The objective of this study is to estimate the contribution of each corrected for the other and a variety of known risk factors.
Using data from 217 U.S. counties of more than 50,000 population where testing data were available in April, 2021, the associations of COVID-19 deaths with politics, testing and other risk factors were examined by Poisson and least squares regression.
Statistical controls for 15 risk factors failed to eliminate the association of COVID mortality risk with percent of vote for Donald Trump in 2016 or negative tests per population. Each is independently predictive of increased mortality.
Apparently, many people who test negative for the SARS-CoV-2 virus engage in activities that increase their risk, a problem likely to increase with the availability of home tests. There is no association of negative tests with the Trump vote but, according to polling data, Trump voters' past resistance to public health recommendations has been extended to resistance to being vaccinated, threatening the goal of herd immunity.
先前的研究发现，与政治和按需检测相关的 COVID-19 传播增加，但并未在同一研究中发现。本研究的目的是估计在纠正其他因素的情况下，以及各种已知风险因素的情况下，每个因素的贡献。
使用 2021 年 4 月在 217 个美国县的超过 50,000 人口的数据，通过泊松和最小二乘法回归，检查 COVID-19 死亡与政治、检测和其他风险因素之间的关联。
对 15 个风险因素进行统计学控制，未能消除与唐纳德·特朗普 2016 年选票百分比或每人口的阴性检测数相关的 COVID 死亡率风险。每一个都是独立预测死亡率增加的因素。
显然，许多 SARS-CoV-2 病毒检测呈阴性的人从事增加其风险的活动，随着家庭检测的普及，这个问题可能会增加。阴性检测与特朗普的投票没有关联，但根据民意调查数据，特朗普选民过去对公共卫生建议的抵制已经延伸到对疫苗接种的抵制，这威胁到群体免疫的目标。
