With the creation of a social distancing policy due to coronavirus disease 2019 (COVID-19), home visit workers are under mental stress as they are treated as the source of infection for COVID-19. Since door-to-door rental equipment examiners and gas inspectors must perform their duties even in the COVID-19 situation, they are being discriminated against so severely. The purpose of study was to examine the mediating role of perceived stress on the relationship between risk perception and fear. Data was collected data through labor unions among 275 home visiting workers who examine rental home appliance equipment or inspecting gas. On-line survey was conducted to assess COVID-19 risk perception, fear, perceived stress, and demographic characteristics. The data was analyzed using PROCESS Macro (Model 4). The results of the study showed that stress plays an important role in increasing COVID-19 fears when COVID-19 risk perception increases. Meanwhile, it was found that COVID-19 fear decreased when the level of perceived stress decreased. To reduce the impact of COVID-19 risk perception on COVID-19 fears, appropriate educational programs to reduce stress should be developed for home visit workers. Policymakers need to develop online or mobile Infectious disease education programs for COVID-19 risk at work and establish policies to apply legal education.
