A little round trip

Number of reinfections, Source: https://science.orf.at/stories/3212535/

For interested friends, I have compiled the data from August 2021 to April 16, 2022 in a table and made a comparison of France, Germany, Tunisia, Portugal, Austria and Iceland. The data is based on the Johns Hopkins University statistics.

The data was taken from here. The notes on the data source (translated into English):

“Note: All key figures depend on the number of tests carried out and the recording and can only be compared to a limited extent. No guarantee for the correctness and topicality of the data.

Statistics from Johns Hopkins University are used for corona infections in over 200 countries worldwide. Johns Hopkins University (JHU) is a private university in Baltimore, Maryland. Data from the JHU’s “COVID-19 Data Repository” is used by health authorities and the media worldwide as a source for spreading COVID-19. Worldwide corona statistics from the JHU are accessed via the freely accessible Our World in Data dataset.

What data does the JHU collect?

The JHU’s COVID-19 data set is maintained by a team at the Center for Systems Science and Engineering (CSSE). Since January 22, 2020, the JHU has been publishing updates on confirmed COVID-19 cases and deaths for all countries worldwide.

How up-to-date is the data?

The JHU updates the data set several times a day. Individual data is obtained from governments, national and sub-national authorities around the world. There may be a delay between the update of the nationally available data and the data from the JHU.

How are the incidence values ​​calculated?

To calculate the 7-day incidence, the new infections from the last 7 days are added up and converted to 100,000 inhabitants (divided by the official number of inhabitants, multiplied by 100,000).

Why the change from ECDC to JHU?

The ECDC announced in November that it would switch from a daily to a weekly update cycle. In order to continue to provide daily updated figures for worldwide COVID-19 infections and deaths, the figures will come from the JHU from December onwards. For a few countries for which the JHU does not have any data, the figures are still obtained weekly from the ECDC.”
