Evaluation of the effectiveness of Washington State's digital COVID-19 exposure notification system over one pandemic year.

ABSTRACT:

Introduction

Digital exposure notifications are a novel public health intervention used during the COVID-19 pandemic to alert users of possible COVID-19 exposure.

Novel estimates of some model parameters are possible because of improvements in the quality and breadth of data reported by WA Notify.

Results

We estimate that WA Notify ave
