399 New COVID-19 Cases Reported

The Wisconsin Department of Health Services reported 399 new COVID-19 cases Sunday from 4,071 processed tests.

The seven-day case total stands at 4,224, below November 18th’s record report of 45,946. The seven-day testing total stands at 31,936, below November 18th’s record rolling total of 133,019 tests.

The testing total is filtered to only include individuals who were tested for the first time or have been tested previously but are receiving their first positive diagnosis.

The seven-day positive case rate, the percentage of tests that confirm a new case of the disease and proxy for if the disease’s spread is growing or slowing, stands at 13.23%, below the record high of 38.12% set December 4th. The 14-day average is 14.55%. The 14-day average set a low of 2.69% on June 19th.

Officials have looked for the positive case rate to trend downward to indicate a slowing spread of disease and sufficient testing.

The Wisconsin Hospital Association reported that 350 people were actively hospitalized with a confirmed case of the disease, an increase of 1 from the day prior and an increase of 32 from a week ago. Thirty days ago the total was 226.

The state reported 42 people were newly hospitalized in the past 24 hours in its daily data release. A total of 28,969 people have required hospitalization since the outbreak began, 412 in the past week.

DHS reported -1 COVID-19 deaths. A total of 6,756 Wisconsin residents have died as a result of the virus, including 1,293 in Milwaukee County. The DHS website includes this note regarding the potential for reporting negative values:

Our goal is to provide the highest quality COVID-19 data with full transparency. In recent weeks, DHS has been able to ramp up data quality assurance efforts in the Wisconsin Electronic Disease Surveillance System (WEDSS), which includes correcting case status from “confirmed” or “probable” where appropriate, ensuring completeness of data fields, and reducing unknowns. Due to these efforts, data displayed on the website may change over time. In particular, dashboards and data tables that track cumulative cases or deaths, as well as those showing newly reported numbers each day may appear lower than expected – in some counties, substantially lower or even negative. For more information on this effort, and details on why the cases and deaths might go up or down from one day to the next, visit our Data 101 webpage.

The 30-day average daily death total now stands at 5.30, below the December 23rd reported record of 53.43. Thirty days ago the rolling average was 8.50.

Since September, Milwaukee County has gone from having the worst per-capita outbreak to the 18th worst in the state. The county fell as low as 26th in early November.

Menominee County has recorded 18,073.9 cases per 100,000 residents (adjusted down). Dodge County has recorded 13,142.8 cases per 100,000 residents (up from 13,140.5). Jackson, Barron, Brown, Trempealeau, Sheboygan, Fond du Lac, Oconto, Juneau, Pepin, Chipewa, Shawano,  Kewaunee, Calumet, Eau Claire and Outagamie are the remaining counties leading Milwaukee.

According to DHS data, 11,039.3 out of every 100,000 Milwaukee County residents (up from 11,027.2) have tested positive for COVID-19 since the outbreak began.

The statewide average of cases per 100,000 residents rose to 10,286.7 (up from 10,279.8).

The City of Milwaukee revised its gating criteria on March 18th in accordance with its new health order. The three criteria are intended to guide what phase of the health order the city should progress to, either loosening or tightening restrictions.

The five-level scale measures range from blue (good, low transmission) to purple (bad, extreme transmission).

The data, last updated April 16th and excluding the four days prior, indicates the city has a high transmission level (110.5) with regards to new cases per 100,000 residents in the past seven days (100-149 is high transmission).

The city has moderate transmission based on the positive test rate (5.6%). Moderate transmission is defined as between 5% and 7.9%.

The adult vaccination rate (which the city defines as any individual over the age of 15 completing the dose course for any COVID-19 vaccine) stands at 20.2%. The low transmission target is 80% and the city has not defined the lower benchmark thresholds.

The city is no longer using hospital bed usage, contact tracing or personal protective equipment supply to guide its COVID-19 health order.

The city is currently in phase six of its health order. According to a chart produced by the health department, the city would enter phase 7 when all three criteria reach the low transmission benchmarks.
