Query: Spatial analysis and prediction of COVID-19 spread in South Africa after
  lockdown   What is the impact of COVID-19 on South Africa? This paper envisages
assisting researchers and decision-makers in battling the COVID-19 pandemic
focusing on South Africa. This paper focuses on the spread of the disease by
applying heatmap retrieval of hotspot areas and spatial analysis is carried out
using the Moran index. For capturing spatial autocorrelation between the
provinces of South Africa, the adjacent, as well as the geographical distance
measures, are used as a weight matrix for both absolute and relative counts.
Furthermore, generalized logistic growth curve modeling is used for the
prediction of the COVID-19 spread. We expect this data-driven modeling to
provide some insights into hotspot identification and timeous action
controlling the spread of the virus.
