“…Firstly, generally the economically weaker people reside in overcrowded areas (high population density). Thus overcrowded or high population density is an important factor of infectious disease transmissions (Ai, Zhang, & Zhang, 2016; Alaniz, Bacigalupo, & Cattan, 2017 ; Jia et al, 2020) even in case of COVID-19 transmissions ( Sun et al, 2020 , Kodera, Rashed, & Hirata, 2020 ; Rocklöv & Sjödin, 2020 ).
