Change in Polish reporting scheme #5399

Closed jbracher closed 2 years ago

jbracher commented 2 years ago

Dear JHU-CSSE team, we would like to bring to your attention a change in the way COVID case numbers are being reported in Poland (in these files: https://arcgis.com/sharing/rest/content/items/e16df1fa98c2452783ec10b0aea4b341/data). Until 8 February, only first infections were counted (in a column called liczba_przypadkow). Now there are three different columns:

  1. liczba_nowych_zakazen is detected cases EXCLUDING reinfections = the same as liczba_przypadkow before 8 February
  2. liczba_ponownych_zakazen is detected reinfections - this has not been reported before 8 February
  3. liczba_wszystkich_zakazen is detected cases INCLUDING detected reinfections, i.e. liczba_nowych_zakazen + liczba_ponownych_zakazen

The JHU data currently seem to contain the data from the liczba_nowych_zakazen column, i.e. without re-infections. The numbers used currently are consistent with those used historically, but we feel like at this stage cases including re-infections may be a more meaningful measure. We have also noticed some confusion among colleagues in Poland due to the resulting discrepancy to official Polish data (specifically with respect to the European COVID-19 Forecast Hub https://covid19forecasthub.eu/ which uses JHU data). We noticed that eg, for the UK a switch to cases including reinfections has been made in the past (https://github.com/CSSEGISandData/COVID-19/issues/5310).

We would be very happy to hear your thoughts on this. Thanks a lot in advance,

Johannes Bracher (Karlsruhe Institute of Technology, Germany) and Marcin Bodych (Wrocław University of Science and Technology, Poland, @eMaerthin)

Thank you very much for raising this issue. We would like to be able to include this data. Is it available on a front end dashboard? Currently, it is unclear whether the dashboard we are using (https://www.gov.pl/web/koronawirus/wykaz-zarazen-koronawirusem-sars-cov-2) is included reinfections in their totals.

Thank you!

Hi, sorry for the delayed reply. The dashboard shows both cases including and excluding re-infections, see this explanation by @eMaerthin:

I hope this helps.

We moreover wanted to mention that these data are also available at the finer geographical levels of voivodeship powiat.
