作为作者过往多年间从事生物气溶胶、颗粒与气态污染物在多种室内高人口密度环境内传播特性及暴露人员健康风险评估相关研究的结合与总结，本书通过独特的视角，从流体力学角度出发，遵循气溶胶类感染物的物理传播特性，辅以计算模拟预测，分析还原了传染性气溶胶从感染者体内释放，到最终被吸入后在他人呼吸道内传输沉积的完整过程。本书的另一特色在于通过将传染性气溶胶的生物特性参数与计算流体力学相结合，提供了一套可量化的健康感染风险评估体系。其成果在科技部国家重点基础研究发展计划（“973”计划）、国家自然科学基金等多个项目的资助下完成。
本书的研究内容属交叉学科，可供建筑环境、生物工程、生物化学、流行病学、公共卫生、病理学等专业的学生及研究人员参考。
