Query Builder for Utah COVID-19 Test - Percent Positivity (Test/Test Method)

Getting Started

CDC proposes three methods for calculating percent positivity. The UDOH uses the third method of number of people tested positive over the number of people tested. The analysis is restricted to PCR and Antigen tests. For a person that has a positive test, their first positive test is used. If there is no positive result for that individual, then their first negative result is used. To calculate the reported 7-day rolling average percent positivity rate, the UDOH tallies the number of people who tested positive in 7 days, divided by the total number of people tested in the same 7 day.

The total number of people who tested positive will not total the total number of cases reported in the state. This discrepancy is due to ongoing investigations and confirmatory testing.

Case and lab data are updated weekly on Thursdays using reported case data

Not all labs are reported with complete demographic and geographic data, tests with incomplete variables will be reported with "unknown". These data may be subsequently reported and updated retroactively.

All data are preliminary and subject to change.

  • Enter start lab collection date (mm/dd/yyyy)


  • Enter end case lab collection date (mm/dd/yyyy)


  • Select one or more subgroups to limit results. Default is all characteristics.

    • First choose a coding scheme to use for age groups. Default is age adjustment age groups, all ages.

    • How to Specify Age Groups

      Enter whole numbers from 0 to 999.

      Use a hyphen to indicate a range of ages (e.g., "5-8" will includes ages 5, 6, 7, and 8).

      You may use greater than (>) and less than(<) symbols. An entry of (<1) yields all infants age 0 through 364 days.

      You may use a plus sign (+) to indicate all ages equal to or greater than (e.g.,"85+" yields all those aged 85 and over).







    • Select ethnicity. Default is all ethnicities.

    • Select one or more subgroups to limit results. Default is all characteristics.

    • Select Sex. Default is all


  • First choose a geography type. Default is all Utah residents, regardless of place of hospitalization.

To display a map, you must select Geographic Area in Display By (category) and None in Group By (series)

Primary group by field

Defines the data's primary grouping dimension. The primary grouping is required and also controls the ordering of the result's data rows. In MS-Excel and other graphing packages this is typically referred to as the the "dataset's category". If viewing in a 2-d table layout then this value/dimension is associated with table's "row" values. Others will refer to this value as the first "cross by" or the first dimension.

Optional secondary group by field

Defines the 2nd field (or dimension) to be used to group and aggregate values by. MS-Excel chart users will commonly refer to this as the dataset's "series" field. If viewing in a 2-d table layout then this field is associated with data table's value columns. Series group bys are optional. Maps and some charts, like the "Pie" chart, are currently not programmed to handle datasets that have more than one group by e.g. they only work with the primary category type group by being specified.

Optional chart graph

Defines the optional chart graphic to display.

NOTE: Maps and some charts, like the "Pie" chart, are currently not programmed to handle datasets that have more than one group by e.g. they only work with the primary category type group by being specified. All other charts will only work with a maximum of 2 group bys e.g. if the fixed group by exists then the series group by can NOT be used with charting or maps.

Optional map graph

Defines the optional map graphic to display.

NOTE: Maps are only available when the category is set to a geographical area and does not have a series defined.

Available Measures

Defines the primary measure value to display in the map and graph.
