COVID-19 Cases Distribution: Pre and Post Achievement of Herd Immunity in Johor Bahru

Public Health issue, specifically COVID-19, has changed the landscape of economics, social interaction, medical services realm, mental well-being as well as our perception in managing the outbreak. Struggling to fight this actively evolving virus, the Malaysian government is on board in supporting the WHO mission to achieve herd immunity by establishing national vaccination program. We are anticipated to analyse reduction and the changes in the spatial and temporal distribution of hotspot by comparing three months data of covid cases before and three months after herd immunity were achieved in Johor Bahru. Moran’s I analysis has been used as the spatial statistics tools to analyse these two datasets. The results of Moran’s I also has been correlated with demographic data such as age group, citizenship and also gender. It is found that the high clustering in Plentong, Tebrau, Pusat Bandar, and Pulai districts was gradually decreasing each month after the herd immunity were achieved.
