Key messages from today’s Data Snapshot

• Cases have been stable for the past four weeks. We currently have a 14-day average of 45 confirmed and probable cases per day. Inpatient hospitalizations increased from 3/20 to 4/2 but have been stable for the past two weeks, and we currently have a 14-day average of 58 people hospitalized with COVID in Dane County hospitals each day.
• Percent positivity is at 7.9% for the past two weeks, and we’re currently averaging 490 PCR tests per day over the past two weeks.
• For the most recent sampling period (4/13-4/18), Madison has a very low COVID wastewater concentration with no significant increase. The Oregon sewershed resumed data collection for COVID wastewater monitoring in January 2023 after a hiatus since June 2022. For the most recent sampling period (3/30-4/13), Oregon has a high COVID wastewater concentration with no significant increase.
• Next month will be the final COVID Data Snapshot. With the ending of the Public Health Emergency on May 11 and the end of the influenza season, we will end the data snapshots and pare down our COVID Dashboard to just hospitalization and death data, updated once per week. We will resume more comprehensive reporting in the fall, inclusive of all respiratory viruses, without a singular focus on COVID.
