Abstract This case study analyzed the field evaluation of cross-infection and infection risk using the tracer gas method in mobile infectious disease isolation facilities, focusing on the concept of indoor air dilution through a three-step protocol. Protocol A determines the release concentration of the tracer gas to be used in the experiment, Protocol B presents a method for measuring cross-infection in a single room, and Protocol C involves a statistical analysis of measurement uncertainties to enhance accuracy and reliability. Based on the presented field evaluation, it is possible to assess the infection risk in an indoor air environment of existing or new medical facilities in practical operation. Therefore, it is considered a valuable operational guideline and verification method to minimize cross-infection, implement an effective air conditioning system, and safeguard healthcare workers' health.
