Abstract

In the year 2020, the COVID-19 outbreak was well-controlled in the Malaysian state of Sarawak. However, there was a surge in positive cases that began in January 2021 and affected all districts, including rural areas with limited health care. Because COVID-19 is extremely dangerous to human health, it is critical to investigate the spreading pattern at the district level. The COVID�19 socio-demographic factor is captured and extracted using Principal Component Analysis (PCA). The dependent variable in this study is COVID-19 cumulative cases and incidence rate while the independent variable is the socio-demographic factors. Because dispersion occurs at different gradient levels across geographies, the Geographically Weighted Regression (GWR) model is used in this study to investigate the relationship between socio-demographic and district-level COVID�19 cases. The finding in this study reveals that there is significant spatial and temporal variation in the spread of COVID-19 across the districts of Sarawak by using GWR. Two independent variables (pop_density and pop_0_14) influence most positively to COVID-19 cases.
