Studies of childhood leukemia have reported a link with residential proximity to electric utility facilities. This paper elaborates on the hypothesis that residential proximity to electric utility transmission-systems is a surrogate for viral contacts, a potential confounder in these studies. While the causal implications of increased viral contacts is not established, the assumption made here is that a significant component of childhood leukemia has an infectious etiology. Increased viral contacts can result from residential mobility, being first born, or use of community childcare facilities. Re-analysis of existing studies should look specifically for the interaction between childhood leukemia, markers for viral contacts (e.g., residential mobility, birth order, use of outside childcare facilities), and residential proximity to high-voltage transmission lines. New study designs should include parameters to test directly for a virus-related infectious model for childhood leukemia.
关于儿童白血病的研究报告称，居住环境与电力设施的距离和该病有关。本文详细阐述了一个假说，即居住在靠近电力传输系统的地方是接触病毒的一个替代指标，而这在这些研究中是一个潜在的混杂因素。虽然增加病毒接触的因果关系尚未确立，但这里所做的假设是，儿童白血病的一个重要病因是感染。病毒接触增加可能源于居住流动性、头胎出生或使用社区托儿设施。对现有研究的重新分析应特别关注儿童白血病、病毒接触标志物（如居住流动性、出生顺序、使用外部托儿设施）以及居住与高压输电线路的距离之间的相互作用。新的研究设计应纳入直接检验儿童白血病病毒相关感染模型的参数。
