COVID-19 update: Over 200 new cases reported in Walworth County portion of the city in past two weeks; It appears only about half were UW-W related

  • It’s not possible to precisely differentiate new cases at UW-W from those in the larger community, but in a recent two week period there were 202 new positive results in the Walworth County portion of the city, and during that period UW-W “only” reported 112. Presumably some of UW-W’s cases would have been reported in Jefferson County. Out of the tests reported in the Walworth County portion of the city in the past week, an alarming 55% were positive. Mandi Kolb, a 911 dispatcher, stated at the virtual WUSD board meeting on Monday evening that she is “taking call after call related to COVID-19.”
  • With a 7-day case incidence as of November 24 of 86.3, Walworth County’s positive cases have moderated slightly, from 92.4 in the past week. The county is still very deeply into the “very high risk” category (which begins at 25) under the Jefferson County model that Whitewater Unified School District (WUSD) is no longer using as guidance. Whitewater’s case incidence, 121, is even higher than Walworth County’s, and continues to climb. Meanwhile, Jefferson County is currently reporting a 7-day case incidence as of November 14 of 85, down somewhat from last week’s 95. The statewide case incidence is reported to be 108.5. (Case incidence = daily average new cases per 100,000 people.)
  • Informed by new guidance from Walworth and Rock Counties, the WUSD board voted on November 23 to pause in-person instruction beginning Nov. 30. With rapidly rising cases in the area, the health departments reverted to Phase I in their COVID-19 guidance and expressed concern regarding the potential for additional spikes related to the upcoming holidays. The school district has now had four school closings since the gradual return to in-person school, with classes going virtual at Lakeview for 11/5-6, at the High School on 11/9, at Lincoln for 11/10-12, and at the High School for 11/20. Though the District Administrator indicated on November 23 that there is only evidence of one student having been infected at school, cases among students have risen considerably. The 29 new staff/student cases (including 6 staff) continued an upward trend, compared with 24 new cases in the previous week. WUSD’s current data indicates that since September 1 there have been 57 positive cases among students and 17 staff members. In-person classes resumed fulltime for 4K – 5th grade on September 28; grades 6-12 began a hybrid model on October 12, and fulltime in-person classes resumed on November 2.
  • UWWs current data shows that last week there were 47 students and 2 staff/others with positive PCR tests, a decline from the 57 students in the previous week. In the initial four weeks of the semester there had been a total of 371 students and 15 others. In the past seven weeks there have been 246 students and 23 others with positive PCR tests. Positive results from the rapid antigen tests that are administered to asymptomatic and random volunteers increased from 1.1% six weeks ago to 1.9% five weeks ago, 3.35% four weeks ago, to 8.15% three weeks ago. With an increase in testing, those results dropped two weeks ago to 5.85% positive, and this past week to 3.6%.
  • Two weeks ago the state introduced a new “critically high” COVID activity level. Per this state website, the state as a whole and all counties except Green now have “critically high” COVID activity levels. Per the state, “COVID-19 remains very contagious and most people in Wisconsin are still at risk of getting sick from the virus.”

Note: On May 12, 2020 the World Health Organization (WHO) advised governments that before reopening, rates of positivity in testing (ie, out of all tests conducted, how many came back positive for COVID-19) should remain at 5% or lower for at least 14 days. If a positivity rate is too high, that may indicate that the state is only testing the sickest patients who seek medical attention, and is not casting a wide enough net to know how much of the virus is spreading within its communities. Wisconsin’s current positivity rate is 36.5%.

WUSD is providing the following “COVID Tracking Data” on its website at this link.

COVID TRACKING DATA

On September 23, 2020 the WUSD School Board voted to suspend the utilization of a community level metric.

UWW has established the following dashboard which provides useful information. It is found at this link.

COVID-19 Dashboard

The COVID-19 pandemic is an ever-changing situation and the University of Wisconsin-Whitewater actively monitors and reviews a series of health, safety, and resource metrics to guide decision-making with regard to university operations. These metrics are considered in combination and consultation with recommendations and orders from the state and county health departments before any changes in operations are made.

Dashboard is updated on business days with available data. Numbers include cases reported through university-coordinated testing, as well as those reported through the COVID-19 Hotline, which may include testing that occurred off-campus through other health clinics/providers. Student employees are counted in the student numbers. The “Other” category is defined as any positive cases reported to UW-Whitewater who are neither students nor employees and may include visitors to the university, contractors or vendors, or others who have been to the university in person.  These numbers represent individuals who have had direct contact with the campuses.  Individuals who are working or attending solely in a remote manner and not living in University Housing are not included.
