Monitoring Incidence of COVID-19 Cases, Hospitalizations, and Deaths, by Vaccination Status — 13 U.S. Jurisdictions, April 4–July 17, 2021
Open accessAbstract
North Carolina, Seattle/King County (Washington), and Utah.Portions of the population in Colorado (49%), Minnesota (55%), New Mexico (61%), and Utah (35%) and the whole population of Maryland are included as part of the COVID-19-Associated Hospitalization Surveillance Network (COVID-NET).https://www.cdc.gov/coronavirus/2019-ncov/covid-data/ covid-net/purpose-methods.html † A COVID-19 case (confirmed or probable) was defined as the detection of SARS-CoV-2 RNA or antigen in a respiratory specimen collected from a person aged ≥18 years per the Council of State and Territorial Epidemiologists' update to the standardized surveillance case definition and national notification for 2019 novel coronavirus disease (COVID-19) (21-ID-01): https://cdn. ymaws.com/www.cste.org/resource/resmgr/ps/ps2021/21-ID-01_COVID-19.pdf.Known cases of SARS-CoV-2 reinfection were excluded.Week ending July 17 (Delta ≥50%) June 20-July 10 (Delta ≥50%) April 4-June 10 (Delta <50%) Abbreviations: PVC = percentage of vaccinated persons occurring among outcomes; PPV = proportion of the population that is vaccinated; VE = vaccine effectiveness.* Vaccination coverage was estimated using the sum of fully vaccinated persons (submitted by the jurisdictions) divided by the combined 2019 U.S. intercensal population estimates by age group.† The expected PVC, represented by the light gray lines, was assessed using the formula: PVC = [PPV-(PPV*VE)]/1-(PPV*VE), where benchmarks are added at different VE values (80%, 90%, and 95%).Observed values that approach or go above the 80% VE line indicate decreased VE. § Two analysis periods, April 4-June 19 and June 20-July 17, were designated based on the threshold week when the weighted percentage of lineages from wholegenome sequencing results submitted to or performed by CDC reached 50% for the SARS-CoV-2 B.1.617.2 (Delta) variant across the 13 jurisdictions.Weekly values are plotted, with the two analysis periods and most recent week for the analysis period shown.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
