Publication number: 20240142350Abstract: The present disclosure provides a test method for assessing the possibility of infection of residents without performing periodic PCR tests of residents of a facility in question. One embodiment is an infectious disease test method that includes a sampling step for collecting a sample from sewage during a sampling period in a route from where sewage is discharged from a facility until flowing into a public sewage pipe, an analysis step for analyzing the sample to obtain information relating to the existence of an infectious disease pathogen in the sample, and a notification step for notifying the facility of the information together with the sampling period.Type: ApplicationFiled: June 18, 2021Publication date: May 2, 2024Applicant: SHIMADZU CORPORATIONInventors: Makoto Yasojima, Hiroaki Takemori, Fumi Daigo, Takuya Tomono
