localcovid19now: processing and mapping COVID-19 case data at subnational scales

Abstract

The localcovid19now R package provides functionality to load, unify and visualize recent COVID-19 case data at subnational scales in order to provide localized situational reports and improve understanding of the scale of local COVID-19 transmission. The package loads data from a variety of data sources and returns the most recent estimate of recorded per capita active COVID-19 infections, the date of the most recent report, and the geometry of each region. These data can then be visualized via mapping documented per capita active infections. We also provide functionality to visualize the risk of exposure to COVID-19 given a particular event size.
