The three-generational household was a focal point of concern for school and community the Coronavirus Disease 2019 (COVID-19) transmission. The current study, using small area data and household variables, reported an approach to neighborhood-level COVID-19 mitigation for school reopening and communities returning to normalcy. The study started with an age-stratified Poisson regression to examine the association between the proportion of three-generational households and COVID-19 infection rates based on data from 74 census tracts in Lancaster County, Nebraska, U.S. from March 5, 2020 to August 22, 2020, followed by mapping the model-based risk score by census tract in the study area. We explored the feasibility of using COVID-19 infection rates and vaccination rates to inform decision-making on school opening from March 5, 2020 to February 3, 2021. The overall infection rate increased by 3% for every unit increased in the percentage of three-generational households after controlling for other covariates in the model. The census tracts were classified into low-, medium-, and high-priority neighborhoods for potential community-based interventions, such as targeted messages for household hygiene and isolation strategies.
三代同堂家庭是学校和社区关注的2019冠状病毒病（COVID-19）传播的焦点。当前的研究利用小区域数据和家庭变量，报告了一种在学校重新开学和社区恢复正常状态时减轻邻里层面COVID-19影响的方法。该研究首先进行了年龄分层的泊松回归，以根据2020年3月5日至2020年8月22日美国内布拉斯加州兰开斯特县74个人口普查区的数据，检验三代同堂家庭比例与COVID-19感染率之间的关联，随后按研究区域内的人口普查区绘制基于模型的风险评分图。我们探讨了利用2020年3月5日至2021年2月3日期间的COVID-19感染率和疫苗接种率为学校开学决策提供信息的可行性。在模型中控制其他协变量后，三代同堂家庭比例每增加一个单位，总体感染率就上升3%。人口普查区被划分为低、中、高优先级社区，以便采取潜在的基于社区的干预措施，如关于家庭卫生和隔离策略的针对性信息。
