SeroTracker synthesizes findings from thousands of seroprevalence studies worldwide, providing a data platform and interactive dashboard for pathogen serosurveillance.

Confirmed cases are just the tip of the iceberg - they undercount the true number of infections because people may have asymptomatic infections or lack access to diagnostic testing. In contrast, seroprevalence studies measure antibodies against a particular pathogen in the population. Because people with these antibodies have been previously infected or vaccinated, these studies are crucial to understanding the true extent of a pandemic and in measuring population antibody levels.

ArboTracker data was collected through a systematic review of published arbovirus seroprevalence studies in collaboration with partners at the

at the Colorado School of Public Health and Heidelberg University Hospital. The search feeding the current dashboard was conducted on March 13, 2023. Data was extracted by researchers at Heidelberg University for each source's estimate(s) and certain relevant subgroups. Additional relevant data was extracted by researchers at SeroTracker.

We produce data for both academic and public use on our dashboard. In May 2024 we updated our search strategy to capture additional data, which will be added to the dashboard in the coming months. A PROSPERO record with a citation can be found

The data on our dashboard are extracted from publicly available independent research and do not reflect validation of the findings on behalf of SeroTracker or any of our funding or collaborating partners. Research studies are heterogeneous and vary in their quality, design, methodology, assay performance, and reporting, and results should be interpreted and compared with caution.
