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.

Exposure Type: Travel exposures include anyone that has traveled outside of Utah 14 days prior to symptom onset. Known contact includes contact with a lab-confirmed case, such as a family member, household member, co-worker, friend, etc.. Cases are categorized as unknown when no travel is reported and the case is not aware of having contact with another lab-confirmed case or if the case is never reached. 

Age Data: The ages of patients displayed in the dashboard are based on the age of the patient at the time of diagnosis. 

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. 

Percent Recovered: The number of cases where more than 14 days have passed since symptom onset or test date for asymptomatic individuals who have not died, divided by the total number of lab-confirmed COVID-19 cases in Davis County. 

Laboratory Testing: Positive cases are reported immediately, while negative results may have a delay before being reported. Laboratory results are presented by the date a sample was collected. Only test results that have the person's residency listed as Davis County are counted. Case counts are presented by the date the case was reported to Davis County Health Department. As a result, the dates reported for positive cases will differ on the two charts. Only results from diagnostic tests are included. 

Testing Numbers and Percent Positivity Calculation: CDC proposes three methods for calculating percent positivity. We are using two of those methods: (1) the number of all positive tests over the number of all tests in a day (the test/test method) and (2) the number of people tested positive over the number of people tested (the person/person method). For the first method, one test per day per person is counted. If a person was tested multiple times in a single day, a true positive test will be counted over a negative. For the second method, one test result per person is counted every 90 days. If there is no positive result for that person, then their first negative result is counted. If a person is tested again more than 90 days after their first test, a new record will be created for the person and their most recent test result will be counted in the percent positivity calculations. If a person has two positive tests with more than 90 days between tests, the case will be investigated as a possible reinfection. The second method is what is used to determine “Tested” numbers on the dashboard. 

Transmission Thresholds: Based on The State of Utah’s Transmission Index, high levels of transmission would be indicated by test/test past 7 day percent positive averages at or above 10%. Moderate transmission would be between 5% and 10% and low transmission would be at or below 5%. 

Small Area Map: The small area map displays rate per 100,000 population. Rate per 100,000 population is calculated by taking the total number of cases in an area and dividing it by the area’s population then multiplying it by 100,000. This allows for an accurate comparison of disease burden to be conducted between small areas with differing population sizes. As of March 15th, 2021, the population data used for calculating these rates are based on 2019 population estimates. 

Total Doses Administered by Other Providers: The total number of vaccines administered, regardless of dose number, to Davis County residents by providers that are not associated with Davis County Health Department as reported by UDOH.

Percent Fully Vaccinated: The number of Davis County residents who completed their COVID-19 vaccine dosing series as reported by UDOH divided by the total county population. Note that those receiving the Johnson & Johnson vaccine will be counted as both having received at least one dose and as fully vaccinated since only one dose is required for that type of vaccine. Total Davis County population was updated to the 2020 population on 11/22/2021. 

Vaccine Clinic Data: The number of COVID-19 vaccine doses administered by Davis County Health Department (DCHD) to persons residing in any county. The performance graph is updated weekly on Mondays. Data is sourced from the DCHD appointment scheduling system. For more information on vaccine distribution, visit https://coronavirus.utah.gov/vaccine-distribution/.

Vaccine Coverage: First dose data from the DCHD clinic scheduling system was combined with first dose data reported to UDOH from other vaccine providers and aggregated by patient age and week they were vaccinated. Counts were then divided by 2019 population estimates for each age group and converted to percentages. This data reflects how many county residents have received at least one dose, meaning many still need an additional dose to be fully vaccinated. Notice the trendlines reflect phased prioritization by Utah Unified Command of older age groups first for vaccine eligibility. Due to change in population size since 2019 and occasional miscategorization of booster doses, some age groups may eventually exceed 100%. The graph is updated weekly on Mondays.
