- U.S. cases pass 15 million. Last week was the deadliest yet as latest 25,000 fatalities added in shortest interval (12 days)
On Thursday (December 10) the U.S. passed 15 million lab-confirmed COVID-19 cases, making it the only nation with more than 10 million. Last week, the daily numbers were grim: nearly 1.4 million new cases were reported, an average of just under 200,000 a day and the trend lines continuing to rise (Figure B).
The numbers were even worse in terms of deaths as Thanksgiving-related illnesses continue to drive daily fatalities to new heights. Last week was brutal with 15,885 COVID-19 deaths, a 12 percent rise over the previous week after four consecutive days of greater than 2,500 deaths (Figure C). Weekly deaths rose in 11 of 12 Northeast states with the biggest gains in Delaware (+76%), and Rhode Island (+43%). Substantial jumps were also seen in the South (Arkansas (+42%) and Virginia (+79%)) and West (Alaska (+50%), California (+50%), and Wyoming (+52%). The Midwest was mixed with 5 states declining in weekly deaths and two states spiking hard: Iowa (+78%) and North Dakota (+58%).
Is the pace of COVID-19 deaths as bad as it was in the worst weeks of April and May? On a number of fronts, the answer is a clear yes. One way is to check the rate at which deaths are occurring nationally. Figure D is my version, counting how many days it takes to add each 25,000 deaths. We went from 25,000 to 50,000 deaths in 13 days starting April 14; until now that was the fastest interval. The jump from 250,000 to 275,000 took just 12 days. We will get to 300,000 faster than that. More hospitals in more parts of the nation are now filled to capacity compared and more state leaders were taking drastic action to stem the tide than is the case now.
Bottom line: Daily cases continue to spiral with no end in sight. The vaccine will not stop this surge in transmission intensity and the resulting carnage. This last week was one of the worst weeks in U.S. history with more deaths recorded in one day than on D-Day or 9/11.
- Maryland update: how to tell if a state is doing better or worse
A couple of days ago, a good friend asked me a good question: the test positivity rate in our state (Maryland) is up to 8 percent, but it was way higher (23 percent) in March. Are we faring better or worse and why do we need to go back into lock down? It’s a good question for my state but also for how to know if things are better or worse in yours. It also shows that people have gotten more sophisticated as disease detectives. Did anyone even know what test positivity rate was a year ago and why that number is so important? The first response I had was that it is not possible to adequately characterize the state of the pandemic in any place by looking at any single number at any single moment. Even if you could say that test positivity is the best number (it’a a candidate for sure), the how-well-is-it-going question requires looking at several key indicators in concert and in a larger temporal context. It’s a bit like baseball. In judging one pitcher over another, we can’t just look at wins, or pitch velocity or any single stat by itself. We need to look at a package of stats to make valid comparisons and we need to see that player in the context of a particular team and season. Let’s go through the top 5 numbers and how they are trending to see if we can hit a home run answer.
We can start with the most basic number – trends in daily cases (Figure F) compiled from the same data source I use for everything else. The Maryland Fall surge started October 23 (715 daily cases) and has soared to now over 3,500 a day (a nearly 5-fold increase). Like every other state, we see two earlier peaks in May and July, and we see a big but temporary dip in cases due to the Thanksgiving reporting hiatus. As smart disease detectives, we know that we can’t compare this peak to the early ones because we were in a completely different testing regime then. We’ll get to that, but we can look at the relative slopes across peaks: the rate of rise is clearly faster now than in spring or summer. One point for things being worse. Next, let’s go to the Maryland Department of Health official numbers for testing volume and test positivity (Figure G). On Friday, the state logged the highest volume of testing (over 66,000); that is 10-times higher than the daily testing totals in April, but it’s also just one day. At its peak, the test positivity rate topped out at 26 percent on April 17. Only 3,800 tests were logged that day. Back then the lion’s share of testing resources were being spent in hospitals verifying the infection status of patients who were already very sick. Almost no testing in the community was yet being done. For lots of reasons, those numbers are apples-oranges compared to now. Maryland increased its testing volume dramatically about mid-July and stayed pretty steady until Mid-November. Comparing test positivity while holding total testing constant is much closer to apples-to-apples. During that time, test positivity trended downward steadily from 5 percent to 3 percent until October 22. We were really doing better. Then (as Figure F shows) the Fall surge started in Maryland. Over the next 6 weeks TPR doubled from 3 percent to a peak of 6.7 percent on December 5. Did testing increases explain that? No. TPR doubled, but testing rose only 20 percent. What about hospitalizations (Figure H)? Compared to the Spring, more acute care beds are full but fewer ICU beds are occupied. That’s because improved treatments are keeping more patients out of the ICU. The overall hospital burden though is higher. Another point for worse. How about deaths (Figure I)? Average daily deaths now are about 6.5 per million, middle of the pack in terms of U.S. states. That’s a 5-fold rise from 1.3 on November 5. It is however 30 percent lower than the 9.7 deaths per million on April 30. It’s apples to oranges again though because case fatality rates have dropped sharply since then as doctors have improved therapies and kept more severely ill patients alive. Remember all the stories about how we were running out of ventilators? Had those advances not occurred, the daily deaths would be roughly double what they are now.
Bottom Line: Are we doing better than the Spring in Maryland? Some yes (lower daily deaths and ICU beds full), some no (cases and test positivity rising faster than the spring, overall hospital beds more occupied, fewer municipalities in lock down). If we add in the bigger context of what is going on in neighboring states, the bottom line is that we are worse off than the Spring, things continue to worsen and the next 4-6 weeks will be the worst yet in Maryland. Comparing the 26 percent TPR in March to where we are now is like comparing a pitcher’s ERA in high school to his numbers in the big leagues. Having said that, if my state’s Republican Governor acted like his colleagues in Iowa and North Dakota, the situation would be MUCH worse. The case for the strongest possible intervention is, for the next month or two, open and shut. It won’t be forever though, the vaccine will bring us the fresh start we crave in late spring and early summer.
- Quirky Qorner: Pandemic weary New Yorkers shell out $100 each for alcohol-soaked hot-tub party in boats on the Hudson river
The Daily Mail carried a story today that made me just say really? This story may say more about the Daily Mail than it does about the Big Apple. The British news organ has published a dozen stories on the coronavirus-hot-tub nexus from an earlier report about a hot tub party bus in Nashville, to the latest Hollywood craze, hot tubs in tents. Someone’s mind is in the gutter.
