A lovely day in Minnesota, which I will ruin by providing you with more CV-19 research summaries.

Health care spending is highly concentrated in a few Americans, and that spending is somewhat persistent.

The year-over-year charts reveal several items which require explanation and more data from DOH.

Active cases appear to be rising, but that is likely an artifact of excessive school testing levels.

Looking at the age groups the item that really stands out is the unnecessary and damaging rise in testing among school-aged groups.

Hospital capacity has dropped substantially in the last few weeks. You know why.

Looking at the proportion of child-age testing and cases shows how school opening leads to bad testing policy.

Another dreary week in CV-19 land, starting with the usual vaccine-heavy research summaries.

Almost all the interesting research seems focussed on vaccines and variants, but I start with a couple of CDC studies with little pearls of useful data.

Two pretty interesting studies on vax versus unvaxed cases and infection protection versus that from vax, and some other summaries.

The epidemic trend in Minnesota appears pretty flat as we headed toward the middle of September, based on the week-over-week change analysis.

Finally, sort of caught up on the research, with more on variants, vaccines, modeling, endemicity and other fascinating topics.

Trying to catch up on actual research, lot of vaccine and some miscellaneous studies.

The latest breakthru data reveals a rapid uptrend in proportion of events among the vaxed.

The CDC continues to work on cementing its reputation as the worst producer of research in the world.
