Case Investigation and Contact Tracing Efforts From Health Departments in the United States, November 2020 to December 2021.

ABSTRACT:

Background

Sixty-four state, local, and territorial health departments (HDs) in the United States report monthly performance metrics on coronavirus disease 2019 (COVID-19) case investigation and contact tracing (CI/CT) activities. We describe national CI/CT efforts from 25 October 2020 through 24 December 2021, which included 3 peaks in COVID-19 case reporting.

Methods

Standardized CI/CT data elements submitted by the 64 HDs were summarized as monthly performance metrics for each HD and the nation. These included measures of CI/CT completeness, timeliness, and workloads. We calculated contact tracing efficacy as the proportion of new cases that occurred in persons identified as contacts within the 14 days before the case was reported.

Results

A total of 44 309 796 COV
