Due to the ECDC switching to weekly data we have update our global data source to be the WHO.

2020-08-28
- Rebased estimates to use
EpiNow2.
- Switched data source to
covidregionaldata.
- Added subnational estimates for Canada.
- Restricted estimates reported to the last 12 weeks of data.
- Updated methods and landing page to link to the new approach.
2020-05-17
- Added regional estimates for Brazil and India
- Approximate sampling is now adaptive. Sampling is exact when cases are below 10,000 in a region and after this point it is approximate.
- Incubation period is now explicitly sampled from with right-truncation dealt with in the same way as for imputed onsets.
- Time window for the effective reproduction window is now optimised at every time point.
- Changed to using a generation time estimate rather than a serial interval estimate (deals with the enforced positivity of the serial interval).
- Switched to using the
forecastHybrid package for generating forecasts as the fable package was shown to have a memory leak when used at scale.
- Moved to using a quasipoisson model for estimating the rate of growth and the doubling time.
- Corrected the sources for the UK and German regional data sources.
2020-05-02
- Switched to approximate sampling of the delay distribution.
- Forecasts are now only shown for countries/regions that have reported at least 200 cases in the last 7 days.
2020-04-25
- Added short term forecasting results.
- Fixed Germany regional map.
- Update plots.
- Fixed doubling time confidence intervals.
- Update palette.
2020-04-18
- Updated the UK data source.
- Fixed data extraction for German regions
- Reduced the lower bound on the number of cases needed to be included in the global nowcast from 100 to 60.
- Squashed the NA category from appearing in the USA map.
2020-04-09
- Updated all estimates with latest data.
- Corrected a mismatch between the data used for the USA on national and statewide level.
- Added additional text explaining why estimates are lagged.
- Updated wording to highlight date of estiamtes.
2020-03-31
- New website to display results.
- Regional breakdowns added for Germany, United Kingdom, and the United States of America.
- National estimates added for all countries that have reported at least 100 cases in a day.
- Update approach to optimise the window used when estimating the Reproduction number.
