Evaluation of the fever check system for visitors using thermography as a measure to prevent the spread of the SARS-CoV-2 infection : including secondary effects obtained from this study

Abstract

The novel coronavirus (SARS-CoV-2) infection, which originated in Wuhan, China, in December 2019, has spread rapidly and infected many people. Many medical institutions have taken measures to detect persons with fever when they enter a building to prevent the spread of the infection. We turned one of the two windbreak rooms in the main entrance as the visitor-only entrance and installed a thermography system, in order to detect persons with a fever above 37.5℃. Although stable results could not be obtained due to the large variation in the detected screening samples depending on the body temperature set by thermography, in retrospect, setting the temperature at 36.5℃ is considered appropriate. However, this study was implemented in non-winter month. A review of temperature settings again in winter is considered as needed.
