Dane County Snapshot release shows increase of overall rate of new cases at 71 per 10,000


Public Health of Madison and Dane County released their new Data Snapshot for October 20 – November 2 which showed the spread of COVID-19 Dane County continues to shift outside of Madison as the rate of new cases continues to increase.

Over the past two weeks, Dane County has seen an overall rate of 71 new cases per 10,000 per the update – up from last week’s 55 new cases per 10,000. According to the chart below, Cambridge, Brooklyn and Town of Dane along with six other areas saw a significant higher rate of cases than the County overall. These numbers only include case and population for Dane County residents.

As noted previously, in September, only 28 percent of cases resided outside of Madison, but current data from October reveal that it is now at 56 percent. This morning, Madison365 has updated our weekly map to showcase the increase in the number of cases in the county by census tract for the weeks of October 22 – November 5. We’ve also noted the top 15 Dane County tracts with the largest increases during this time.

From October 20 – November 5, there were 3,879 total cases. Of those cases, 2,525 were fully interviewed and the following was found:

  • 33 percent of cases had household contact with another COVID-19 case
  • 33 percent of cases had non-household contact with another COVID-19 case
  • 24 percent of cases attended a gathering or party in the past two weeks
  • 9 percent of cases were from UW – 297 were UW students and 51 were college staff

Also provided from the data, the following associated cases from unique clusters and facility investigations with non-clusters:

  • Workplaces not, public facing – 27 unique clusters in workplaces that are not public-facing, with 58 associated cases while there 8 facility investigations with 11 associated clusters
  • Public facing workplaces – 12 unique clusters in public-facing business/services with 25 associated cases and 5 facility investigations with 8 associated cases
  • Bar/Restaurants – 12 unique clusters with 22 associated and 1 facility investigation with 2 associated cases
  • Childcare facilities – 10 unique with 27 associated cases (12 children and 15 adults) and 8 facility investigations of non-clusters with 9 associated cases
  • Skilled Nursing – 7 unique clusters with 38 associated cases and 1 facility investigations with 1
  • Health Care facility – 7 unique clusters with 36 associated cases and 7 facility investigations with 12 associated cases
  • Schools – 5 unique clusters with 26 associated cases (14 children and 12 adults) and 39 facility investigations with 39 associated cases (16 children and 23 adults)

For October 20 – November 2, Dane County has averaged 277 cases per day, an increase from last week’s 214 – which keeps this metric in the red according to PHMDC’s reopening plan. As of Wednesday, November 4, PHMDC announced Dane County increased that average to 300 cases per day. The data also shows, for this two week period, the percentage of positive tests for the most recent 14 days has increased from last week’s update of 5.0 percent to 6.0 percent – keeping that metric yellow.

The percentage of cases contacted within 48 hours dropped to an all time low to 19 percent from last week’s 26 percent. The proportion of new cases from October 20 – November 2 who did not know where they had contracted COVID-19 decreased to 30 percent. Both of these metrics remain in the red.

The snapshot included a look at hospitalizations, which have continued to grow in Dane County as well as across the state. Though only 68 people were hospitalized in that two-week period, those who identify as Hispanic or Latinx continue to be over represented in the data for both cases and hospitalizations along with those who are American Indian/Alaska Native. The Hispanic or Latinx community make up six percent of the population in Dane County and for those two weeks, were seven percent of testing. However, Hispanic or Latinx residents were 18 percent of cases and 13 percent of hospitalizations for October 20 through November 2. Those who are American Indian/Alaskan, however, are .3 percent of the population but .4 percent of cases and 1 percent in hospitalizations. Black people in Dane County though at their population for both cases and hospitalizations according to the data this week, but were under represented in testing. Asian people in Dane County were reportedly under represented in cases, hospitalizations but testing as well in comparison to their population.

Hospitalizations among age groups continue to increase in the County as 2 percent of cases from October 20 through November 5 were hospitalized. Those who were in their 70s, 80s and 90s each made up 14 percent of all those hospitalized.

Once again, all age groups continue to increase their cases as compared to last week with those 80 and older experiencing the largest increase as compared to last week’s update.


Madison365 will have an update numbers for the state later this afternoon.
