Published Data

General useful data sources

The COVID-19 Response Measures Database, compiled by the European Centre For Disease Prevention and Control (ECDC). The database is an archive of non-pharmaceutical interventions, or measures, introduced by 30 countries in the European Union and the European Economic Area in response to the coronavirus disease (COVID-19) pandemic, including the start and end date of each measure. The database is reviewed and updated every two weeks.

Data available from research groups in Sweden

The list of available data on this Portal was curated manually until February 2022. After February 2022, we instead began to use a script to query the Europe PMC database (making use of their API) in order to locate relevant publications. We only include data from publications about COVID-19/SARS-CoV-2 that BOTH involve at least one author affiliated with a Swedish research institution AND openly share reusable data and/or code. The code used for the query is written in Python and, as with all of our code, it is openly available in GitHub. We welcome others to reuse it and to repurpose it for other pathogens.

The lists of available data may not be exhaustive as the script used to generate it does not search for every possible database/repository. If you find that a dataset is missing, or that the information related to it is incorrect, please get in touch with us
