Data Notes 

Case data: Lab-confirmed cases are displayed based on the date the case is reported to Davis County Health Department. At this time, the state of Utah is considering both SARS-CoV2 PCR and antigen tests as confirmatory testing for COVID-19 infection.

Death Counts: Deaths reported by UDOH include confirmed and probable cases as defined by the Council of State and Territorial Epidemiologists (CSTE) case definition. This includes: 1) confirmed cases with a positive COVID-19 PCR result and no alternative cause of death noted on the death certificate or reported by the Office of the Medical Examiner (OME), 2) probable cases where the death certificate lists COVID-19 disease or SARS-CoV-2 as a cause of death or a significant condition contributing to death and no alternative cause of death reported by the OME, and 3) probable cases with COVID-19 symptoms and close contact to a laboratory confirmed case and no alternative cause of death reported by the OME or the death certificate. Death counts are provisional and subject to change as investigations are completed.

Hospitalization Data: Hospitalizations represent the cumulative number of lab-confirmed COVID-19 cases that have been admitted to a hospital due to COVID-19. This count does not represent the number of COVID-19 cases currently in the hospital. The data captures hospitalizations reported by cases and providers. Some hospitalizations may not be included in this count due to reporting gaps. 

Variant Data: The Utah Public Health Laboratory (UPHL) and other laboratories in Utah are performing Whole Genome Sequencing (WGS) on a subset of PCR samples as a surveillance tool to monitor for variants. Shown are the percent of variants of concern (VOCs) and variants being monitored (VBMs) by week in Davis County residents. Due to the time is takes to conduct WGS, there will be a delay in reporting. 

Vaccine Data: Overall vaccination rates (i.e. percents, per 100 population) are calculated by dividing the number of Davis County residents vaccinated, as reported by UDOH, divided by the total county population. For the graph, fully vaccinated is defined as the number of Davis County residents of a certain age who completed their COVID-19 vaccine dosing series divided by the county population for that age group. A completed series is defined as two doses of Pfizer or Moderna, or one dose of Johnson & Johnson vaccine. Notice the trendlines reflect phased prioritization by Utah Unified Command of older age groups for vaccine eligibility. Population totals were updated to 2020 counts on 11/22/2021.
