The current study aimed to illustrate U.S. COVID-19 reporting quality by examining epidemiological surveillance from U.S. health departments in 50 states and the District of Columbia between July and August 2020 along five central quality dimensions: timeliness, reliability, completeness, accuracy, and accessibility. A follow-up assessment was conducted 19 months later for a subset of states. Results broadly demonstrated that the quality of COVID-19 data reporting was significantly heterogenous. States varied in timeliness of initial data reports (median: 3\/2\/2020, minimum: 9\/29\/2019, maximum: 4\/20\/2020). Most states (56.8%) did not indicate sources of data for their official published reports. In assessing for 10 standard variables from the Centers for Disease Control and Prevention (CDC), states widely differed in granularity of reported variables and no state health department reported data for all CDC surveillance variables (e.g., race, ethnicity, sex). Most same-day comparisons of state-specific counts reported by the CDC differed from respective state health departments (cases: 84.3% differed; deaths: 68.6% differed). Follow-up examination indicated improvements in reliability, accuracy, and accessibility, but issues in data source verification and completeness persisted. Authors conclude with recommendations to improve disease mitigation efficiency and improve public trust in health protection efforts: establish formal reporting guidelines; standardize operational definitions for key disease variables; and, require health departments to publicly identify sources of reported data.<\/jats:p>","DOI":"10.1371\/journal.pone.0319263","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T18:41:01Z","timestamp":1740163261000},"page":"e0319263","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["Multi-level quality assessment of United States COVID-19 epidemiological surveillance"],"prefix":"10.1371","volume":"20","author":[{"given":"Megan S.","family":"Irgens","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1881-2758","authenticated-orcid":true,"given":"Riley M.","family":"O\u2019Neill","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John M.","family":"Ruiz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2025,2,21]]},"reference":[{"key":"pone.0319263.ref001","author":"World Health Organization","year":"2023"},{"issue":"9","key":"pone.0319263.ref002","doi-asserted-by":"crossref","first-page":"e0238678","DOI":"10.1371\/journal.pone.0238678","article-title":"Assessing the potential impact of COVID-19 on life expectancy","volume":"15","author":"G Marois","year":"2020","journal-title":"PLoS One"},{"issue":"2","key":"pone.0319263.ref003","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1215\/03616878-8802162","article-title":"Pandemic Politics: timing state-level social distancing responses to COVID-19","volume":"46","author":"C Adolph","year":"2021","journal-title":"J Health Polit Policy Law"},{"key":"pone.0319263.ref004","first-page":"45","article-title":"The health belief model.","volume-title":"Health behavior and health education: theory, research, and practice","author":"VL Champion","year":"2008"},{"issue":"4","key":"pone.0319263.ref005","doi-asserted-by":"crossref","first-page":"e0008149","DOI":"10.1371\/journal.pntd.0008149","article-title":"Understanding the role of disease knowledge and risk perception in shaping preventive behavior for selected vector-borne diseases in Guyana","volume":"14","author":"C Aerts","year":"2020","journal-title":"PLoS NeglTrop Dis"},{"issue":"2","key":"pone.0319263.ref006","doi-asserted-by":"crossref","first-page":"364","DOI":"10.3201\/eid1002.030418","article-title":"Crisis prevention and management during SARS outbreak, Singapore","volume":"10","author":"SR Quah","year":"2004","journal-title":"Emerg Infect Dis J - CDC"},{"issue":"1","key":"pone.0319263.ref007","doi-asserted-by":"crossref","first-page":"1751","DOI":"10.1186\/s12889-020-09892-y","article-title":"The impacts of knowledge, risk perception, emotion and information on citizens\u2019 protective behaviors during the outbreak of COVID-19: a cross-sectional study in China","volume":"20","author":"L Ning","year":"2020","journal-title":"BMC Public Health"},{"issue":"9","key":"pone.0319263.ref008","doi-asserted-by":"crossref","first-page":"e37846","DOI":"10.2196\/37846","article-title":"Public health information seeking, trust, and COVID-19 prevention behaviors: cross-sectional study","volume":"24","author":"EK Tetteh","year":"2022","journal-title":"J Med Internet Res"},{"key":"pone.0319263.ref009","author":"U.S. Department of Health and Human Services.","year":"2017"},{"issue":"5","key":"pone.0319263.ref010","doi-asserted-by":"crossref","first-page":"5170","DOI":"10.3390\/ijerph110505170","article-title":"A review of data quality assessment methods for public health information systems","volume":"11","author":"H Chen","year":"2014","journal-title":"Int J Environ Res Public Health"},{"key":"pone.0319263.ref011","first-page":"1","article-title":"Quality assessment methodologies for linked open data","volume":"1","author":"A Zaveri","year":"2013","journal-title":"Submitted Seman Web J"},{"key":"pone.0319263.ref012","author":"R Core Team","year":"2020"},{"key":"pone.0319263.ref013","unstructured":"Di Lorenzo P. usmap: US Maps Including Alaska and Hawaii. 2024.
