Population-scale longitudinal mapping of COVID-19 symptoms, behaviour and testing.

ABSTRACT: Despite the widespread implementation of public health measures, coronavirus disease 2019 (COVID-19) continues to spread in the United States.

Here, we report results from over 500,000 users in the United States from 2 April 2020 to 12 May 2020. We show that self-reported surveys can be used to build predictive models to identify likely COVID-19-positive individuals. We find evidence among our users for asymptomatic or presymptomatic presentation; show a variety of exposure, occupational and demographic risk factors for COVID-19 beyond symptoms; reveal factors for which users have been SARS-C
