Local Covid Tracker

This shiny dashboard was built to track local COVID-19 infection levels across England and Wales. The methods used were based on those described in this paper. It was retired in July 2022. You can still run it directly from an R installation using this GitHub code.

COVID-19 transmission routes

We analysed the routes of infection of COVID-19 and showed that a high proportion of infections come from pre-symptomatic and asymptomatic individuals. This means that contact tracing needs to be fast and scalable to be an effective intervention towards controlling the epidemic.

This shiny app enables you to explore our results and test their sensitivity to our modelling assumptions.
