Another week, another of Dave Dixon's sterling set of age group charts.

The title for this series seems apt as the epidemic and resulting research just won't let go.

A couple of quick health care research notes, including the latest on national health care spending.

Still keeping up with the research Joneses.

The vast majority of cases are not being reported, but the hospitalization and case rate is extremely low.

The age group version of breakthrough event analysis.

Repeat after me: ITS AN EPIDEMIC OF THE VAXED!!

Another long-term look at the epidemic, variation in reported testing makes case comparisons hard and seasonal effects are not completely clear.

A few more studies trickled out in the last couple of days.

We may be near the peak in cases in Minnesota's most recent wave, according to the week-over-week analysis.

Another week of looking at events by age group, with a general increase in events.

Our look at wastewater data for tracking the epidemic.

Once more into the research breach.

The age structure charts for breakthrough events pictorially indicate declining and low vaccine effectiveness in several age groups, particularly against cases.
