Tests, Cases, and Hospitalizations Keep Dropping: This Week in COVID-19 Data, Aug 13

Testing continues to fall, especially in the South, one of the areas where the country needs it the most. Cases, too, are falling, which remains hard to interpret, given the testing decline—but fewer people are now in the hospital with COVID-19 than last week. This is the second week in a row that hospitalizations seem to have dropped, which suggests that infections may be declining independently of testing reductions.

Hospitalization Data Reported by the HHS vs. the States: Jumps, Drops, and Other Unexplained Phenomena

Is There a Right Way to Chart COVID-19 Deaths Over Time?

To analyze how the pandemic is trending across the country, understanding the relationship between these two data points is crucial. Here's what we've learned from investigating both methods in three of our largest hotspots: Arizona, Florida, and Texas.

Florida’s Per-Capita COVID-19 Cases Just Surpassed New York’s, but Are the Two Outbreaks Comparable? Yes and No.

Florida has reported over 461,000 total COVID-19 cases, surpassing New York for the highest per-capita caseload in the United States—but a simple comparison doesn’t represent the critical differences in the data we have for the two outbreaks.

Cases Declining, Deaths Rising, Hospital Data Remains a Question Mark: This Week in COVID-19 Data, July 30

This week’s data brings the first good news in several weeks: new cases of COVID-19 are declining nationally, thanks to substantial declines in reported cases by states with major outbreaks. Deaths, which lag cases, continue to rise. And hospital data is still unreliable for the second week in a row.
