The Inspiration

AFTERPARTY–19 grew out of experiences we had at the 2023 Convention of the Democratic Socalists of America in Chicago. At the convention, organizers from SCORE and the DSA Disability Working Group fought for the National Resolution DSA Organizing for Pandemic Justice. Immediately after the convention, numerous people tested positive for COVID–19.

After the convention, both DSA staff and organizers from the Disability Working Group began reactive parallel efforts to assess the impact by attempting to count how many people tested positve. We discovered that in the heat of the moment, it was very difficult to set up a contact tracing effort using the limited resources of a staff that was dealing with the convention tear-down and attendees that were exhausted from the convention and traveling. This made it clear that such resources needed pre-positioning. Additionally, there was a scramble for the appropriate way to perform the count. Public announcements on social media and Slack were invaluable. Some people privately reported aggregate numbers to us ("X people from this group are sick or testing positive"), but the aggregates could be overlapping as people belonged to multiple groups.

It's necessary for individuals to be able to confidentially report their COVID–19 status to event organizers. Google Forms are often used for this, but some people do not want to engage with Google's applications (note: AFTERPARTY–19 is a custom application deployed on Google Cloud Platform). AFTERPARTY–19 is a solution to this problem that can scale and be utilized at the touch of a button.
