Key messages from today’s Data Snapshot

• Cases were stable from 12/19-1/1 and then decreased over the past two weeks. We currently have a 14-day average of 60 confirmed cases per day. Inpatient hospitalizations have been stable over the past month, and we currently have a 14-day average of 60 people hospitalized with COVID in Dane County hospitals each day. Percent positivity decreased from 8.9% two weeks ago to 6.5% for the past two weeks. We’re currently averaging 924 PCR tests per day over the past two weeks.
• For the most recent sampling period (1/6-1/12), Madison has a moderate COVID wastewater concentration with no significant increase (but is trending upwards). For the most recent sampling period (12/15-1/10), Sun Prairie is at a very low COVID concentration with no significant increase. Note that the Madison sewershed is sampled at a higher frequency than the Sun Prairie sewershed; because of this, it is likely that the Madison wastewater data is more precise in comparison to Sun Prairie.
• The current 7 day average of people hospitalized with COVID in Dane County hospitals is 71% lower than the same date last year, and 39% lower than the same date in 2021. The current 7 day average of people in the ICU with COVID is 91% lower than the same date last year, and 85% lower than the same date in 2021.
• Statewide, influenza (specifically Influenza A) is the predominant circulating non-COVID respiratory virus. The prevalence of all respiratory viruses appears to be stable or declining, but it’s possible there could be future surges yet this winter.
