Data Notes 

Case data: Lab-confirmed cases are displayed based on the date the case is reported to Davis County Health Department.  The actual number of cases in Davis County is higher than what is reported due to mild cases not feeling ill enough to seek care, clinician judgement for testing, and expanding laboratory capacity.

Cases by Week: Weeks since the first reported lab-confirmed case in Davis County.   

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 community acquired when no travel is reported and the case is not aware of having contact with another lab-confirmed case.  

Age Data: The ages of patients displayed in the dashboard are based on the age of the patient at the time of diagnosis. Less than five total cases within a specific age group will not be reported at this time.

Hospitalization Data: Hospitalizations represent the cumulative number of lab-confirmed COVID-19 cases that have been admitted to a hospital. 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.

Laboratory Testing: As of March 19, 2020, all major private and public laboratories in Utah are reporting positive and negative COVID-19 (SARS-CoV-2) results. Positive cases are reported immediately, while negative results may have up to a delay before being reported. Due to reporting differences, testing numbers and results prior to March 19 may be under-reported. Laboratory results are presented by the date a sample was collected. 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. Any tests conducted before March 1, 2020 are not displayed on this graph. 

Percent Testing Positive: The number of Davis County lab-confirmed COVID-19 cases divided by all Davis County lab tests.

Hospitalization Rates: The number of Davis County lab-confirmed COVID-19 cases ever hospitalized divided by all Davis County lab-confirmed COVID-19 cases.

Percent Recovered: The number of people that have been released from isolation protocols according to the Centers for Disease Control and Prevention’s discontinuation of isolation guidelines: https://www.cdc.gov/coronavirus/2019-ncov/hcp/disposition-in-home-patients.html, divided by the total number of lab-confirmed COVID-19 cases in Davis County. 

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.
