Very stable proportion of cases and hospitalizations the past few weeks. Deaths fluctuating more. Boosters could be having an impact on hospitalizations and deaths in the elderly. Thanks to Dave Dixon and here are his notes:
Notes, Sources, and Methods:
1. The table and chart are updated for new data released by MDH on 12/06/2021, adding week starting 10/31/2021. The source is the data file https://www.health.state.mn.us/diseases/coronavirus/stats/vbtcounts.xlsx found on MDH web page https://www.health.state.mn.us/diseases/coronavirus/stats/vbt.html. Other than adding data for the week of 10/31/2021 there are no changes to data for the prior weeks.
2. The data provided in the data file vbtcounts.xlsx is used without modification, other than to sum the weekly events and compute the breakthrough proportion. Vbtcounts.xlsx provides breakthrough and non-breakthrough cases, hospital admissions, and deaths for each week listed.
3. MDH defines a breakthrough event as a Covid case, hospital admission, or death that occurs 14 or more days after completing the vaccination shots (not including boosters).
4. The data published by MDH in this data file contains cases for those 12 and over only. Including cases for those under 12 would tend to decrease the breakthrough proportions somewhat for cases, but almost not at all for hospital admissions (because there are so few admissions for those under 12), and even less for deaths.
The proportion of breakthrough cases for the week starting 10/31/2021 was 44.4%, a new high. The breakthrough proportion of hospital admissions was lower than the week before at 33.0%, and deaths also lower at 36.1%.
