Data note

Disclaimer: Big Lake Data LLC does not provide any representations, assurances, or guarantees regarding the accuracy or completeness of Wisconsin DHS data.

The data presented in these reports is retrieved directly from the daily reports created by the Wisconsin Department of Health Services (WI DHS). Detailed descriptions of their data may be downloaded here.

DHS states:

All data are laboratory-confirmed cases of COVID-19 that we freeze once a day to verify and ensure that we are reporting accurate information. These numbers are the official state numbers, though counties may report their own totals independent of DHS. Combining the DHS and local totals may result in inaccurate totals. Data included in these tables are subject to change. As individual cases are investigated by public health, there may be corrections to the status and details of cases that result in changes to this information. Deaths must be reported by health care providers, medical examiners/coroners, and recorded by local health departments in order to be counted.

Big Lake Data includes the following DHS variables in these reports.

  • POS_NEW_CP - Number of people who had confirmed or probable cases of COVID-19 newly reported since the previous day. Each person can only be reported as a confirmed case once. Although very rare, a person may be reported as a probable case more than once, depending on how they met the case definition (e.g., if they were a symptomatic close contact of a confirmed or probable COVID-19 case but were never tested during their illness).
  • POS_7DAYAVG_CP - Rolling 7-day average of POS_NEW_CP, the number of people who had confirmed or probable cases of COVID-19 newly reported since the previous day.
  • TESTS_7DAYAVG - Rolling 7-day average of TESTS_NEW, the number of diagnostic, confirmatory test results for COVID-19 (molecular, PCR or NAAT test to detect SARS-CoV-2 RNA) newly reported since the previous day. Because the number of people with test results includes only Wisconsin residents who had test results reported electronically to DHS, TEST_NEW underestimates the total number of Wisconsin residents tested. If a person has a diagnostic, confirmatory test more than once, they are included and counted in this measure each time they are tested.
  • DTH_7DAYAVG_CP - Rolling 7-day average of DTH_NEW_CP, the number of people who had confirmed or probable cases of COVID-19 and died from COVID-19 related causes newly reported since the previous day, and if date of death occurred within 30 days of being reported.
  • HOSP_YES_CP - Cumulative number of people with confirmed or probable cases of COVID-19 who were ever hospitalized for COVID-19.
  • POS_0_9_CP - Cumulative number of confirmed or probable cases, ages 0–9 years.
  • POS_10_19_CP - Cumulative number of confirmed or probable cases, ages 10–19 years.

Big Lake Data derives the following variables from the DHS data in the manner described.

7-day average of new hospitalizations

Daily new hospitalizations are calculated by subtracting yesterday’s cumulative hospitalization figure (HOSP_YES_CP) from today’s. Then, BLD calculates right-aligned rolling 7-day average of daily new hospitalizations. Please note: There are many cases with unknown hospitalization status due to limited resources for individual case follow-up and documentation. This figure is likely an undercount.

7-day average of new cases among the population 0-9 and 10-19

For both these variables, the daily new number of cases is calculated by subtracting the previous day’s cumulative total from today’s cumulative total. Then, a rolling 7-day average is calculated.

Burden Rate

The burden rate is the cumulative number of cases over a period of time, expressed as a rate per 100,000 people.

Due to idiosyncracies in daily data reporting, it is necessary to define the burden rate period as a multiple of 7. BLD calculates both 14 and 7-day burden rates. The 14-day burden rate is the figure used by WI DHS to classify COVID-19 disease activity. The 7-day burden rate may also be helpful, as it responds more swiftly to new events.

BLD finds the burden rate by calculating a rolling 14 (or 7) day cumulative number of cases (POS_NEW_CP). This rolling sum is then divided by the geographic area’s population and multiplied by 100,000. A 14-day burden rate of 1,000 means that 1% of that area’s population tested positive for COVID-19 in the previous 2 weeks. A 7-day burden rate of 1,000 means that 1% of the population tested positive in just the previous week.

A note on population

2020 population totals are used for the State of Wisconsin and Milwaukee County. WI DHS provides tract-level data using 2019 tract boundaries. For this reason, tract-derived burden rates are calculated using 2015-19 American Community Survey population estimates.
