DHS Releases New Data on COVID-19 Cases, Hospitalizations, and Deaths by Vaccination Status
The Wisconsin Department of Health Services (DHS) has launched a new data webpage, COVID-19 Illness After Vaccination, which includes a visualization showing the rate of COVID-19 cases, hospitalizations, and deaths per 100,000 among individuals who are fully vaccinated versus individuals who are not fully vaccinated. These data are also presented by month, beginning in February 2021. The new visualizations show the rate of confirmed and probable COVID-19 cases per 100,000 amongst the two groups.
Vaccine breakthrough cases are expected and increase as a proportion of total cases as vaccine coverage increases. COVID-19 cases amongst individuals who are fully vaccinated continue to represent a very small percentage of total cases since the beginning of the year. Breakthrough infections shown in the data only include those that meet the CDC vaccine breakthrough infection definition. The not fully vaccinated population includes all Wisconsin residents with no COVID-19 vaccine doses reported in the Wisconsin Immunization Registry (WIR), an incomplete COVID-19 vaccine series, and those who have not completed the two weeks following vaccination to build full immunity. The COVID-19 vaccines are still doing their job by preventing severe illness, hospitalization, and death.
The COVID-19 vaccines remain the best way to protect yourself, your family, and your community from COVID-19 and the highly infectious Delta variant. Unvaccinated people should get vaccinated and following local public health guidance. With the Delta variant, it is more urgent than ever. High vaccination coverage will not only reduce the spread of the virus, but also help prevent new, and possibly more concerning, variants from emerging. To find a vaccination location near you visit vaccines.gov (https://vacunas.gov/) or call 211.
DHS has also made two other data updates this week. The COVID-19 cases and deaths by county and census tract, municipality, school district, and zip code have been updated to align with the color scheme used by the Centers for Disease Control and Prevention (CDC) case-rate definitions used to determine level of community transmission on the CDC COVID Data Tracker. This alignment with CDC’s tracker is important for local decision makers to elect on layering COVID-19 prevention measures within the community based on levels of community transmission and vaccination coverage. DHS has also updated the New confirmed COVID-19 cases by date confirmed, and 7-day average graph to include a date slider. The new function allows users to zoom in on a particular segment of the graph.
