We're researchers from the Harvard T.H. Chan School of Public Health interested in understanding in what settings people are exposed to SARS-CoV-2 (the virus causing COVID-19), especially as it relates to racial, ethnic and socioeconomic disparities in infection risk. We've designed a survey to measure SARS-CoV-2 exposure risk in the household, on transportation, and at the workplace that can be used in conjunction with serological testing to identify risk factors for and modifiers of exposure. The survey can be demoed via Qualtrics [here][1]. All responses using this link are anonymous and will be deleted. We would like to thank Dr. Marie-Claude Couture (University of San Francisco) and Dr. Nancy Krieger (Harvard T.H. Chan School of Public Health) for their helpful feedback and contributions. This survey was developed by Emma Accorsi, Tori Cowger, and Dr. Marc Lipsitch at the Center for Communicable Disease Dynamics at Harvard T.H. Chan School of Public Health. Please contact eaccorsi@g.harvard.edu with any questions. **Questions adapted from:** Q11, Q23, Q46 - American Community Survey; Q9, Q10, Q12, Q13, Q24, Q43, Q44 - U.S. Census Bureau 2020 COVID-19 Household Pulse Survey; Q7, Q8, Q18, Q25 - John Hopkins University COVID-19 Community Response Survey **Suggested citation:** Accorsi, E.K., Cowger, T., Lipsitch, M.
