This project investigates in which types of settings SARS-CoV-2 transmission tends to take place. We collect examples of transmission events from around the world —ranging from cases of individual transmission to large superspreading events— catalog and analyze the features of the settings in which they occurred, and present the findings in a publicly accessible database that can be used by public health officials, researchers, organizations and the public to devise better, more targeted strategies of protection against the virus.


  • Google sheet: view the database; download or make a copy to edit and sort

  • Bubble map: shows all the superspreading events in the database on a world map; click on a bubble to find more information about an event

  • Bubble map with timeline: same but with an animated timeline showing the events as they occurred in time

Because we want the database to be of use to researchers, policy makers, public health institutions, industry and the public, we welcome opportunities to spread the word about the database. 

If you are a journalist looking for more information about the project or if you can help with contacts in the media, public health institutions and industry, please send us a message at contact@superspreadingdatabase.com


We are always looking for new transmission events to add to the database. If you come across an event not yet in the database, you can suggest it here. If you'd like to commit some time to do a more systematic search please contact us at info@superspreadingdatabase.com. We are particularly interested in assistance with searching non-English language literature.

In addition to finding new examples we are also looking for volunteers to help us investigate, verify and systematize information about the events already in the database, using protocols we have set up for this purpose.
