4. In this paper, the monitoring of sewage and wastewater for population level assessment of infection mentioned in smart city applications and urban automation was added as a limitation of this study. In the opinion of reviewers, epidemics in cities are not simply spread by one factor. Therefore, various factors should be dealt with, but in this paper, only heat and movement lines, which were mainly dealt with in Korea. The added part is as follows. Conclusion: “… Also, epidemics in cities are not spread simply by one factor. It is important to operate the monitoring system for sewage and wastewater for population level assessment of infection, which is considered to be the most important source of infection. 2 Therefore, they should be considered in future research.
I'd argue that one of the areas in which Smart City applications (in particular) and urban automation (in general) have been most important during the COVID pandemic - the monitoring of sewage and wastewater for population level assessment of infection - isn't even mentioned. I think that is both a big oversight, and an opportunity for critics. I think that piece needs to be included and worked into any assessment of smart cities and pandemics. Additionally, I've included a few other pieces on COVID and smart cities.
