Siew Bee Aw,Bor Tsong Teh,Gabriel Hoh Teck Ling,Pau Chung Leng,Weng Howe Chan,Mohd Hamdan Ahmad +5 more
TL;DR: In this article, the impacts of population density on the spread and severity of COVID-19 in Malaysia were investigated using a parametric approach of the Pearson correlation, and it was found that population density has a moderately strong relationship to cumulative COVID19 cases and a weak relationship to infection rates.
