Our COVID Mortality Rate Is Down 85%?

Posted on by

That’s a statistic in the news, but what does it mean? CNN reported this on Friday:

Friday’s case count of at least 80,005 surpasses the country’s previous one-day high of 77,362, reported July 16, according to Johns Hopkins University.
 
US Surgeon General Dr. Jerome Adams cautioned earlier Friday that hospitalizations are starting to go up in 75% of the jurisdictions across the country, and officials are concerned that in a few weeks, deaths will also start to increase.
 
The good news, Adams said, is that the country’s Covid-19 mortality rate has decreased by about 85% thanks to multiple factors, including the use of remdesivir, steroids and better management of patients.
 
According to CNN, the Surgeon General  made these remarks during an online discussion of global health policy at Meridian Global Leadership Summit. Meridian is a “non-profit, non-partisan diplomacy center” in Washington. I couldn’t find exactly what he said, either from Meridian’s site, the Surgeon General’s site or the Surgeon General’s Twitter account. The Center for Disease Control doesn’t seem to report a mortality rate.
 
Looking at statistics from The New York Times, however, indicates what the Surgeon General was talking about. Back in mid-April, the US was reporting around 2,200 deaths for every 32,000 confirmed cases. Now 800 deaths are being reported for around 68,000 cases. That translates into 6.9% of cases ending in death in April vs. 1.2% now, a decline of 83%. So it’s true that the mortality rate has dropped quite a lot.
 
This is confirmed by two studies reported by National Public Radio:
 
Two new peer-reviewed studies are showing a sharp drop in mortality among hospitalized COVID-19 patients. The drop is seen in all groups, including older patients and those with underlying conditions, suggesting that physicians are getting better at helping patients survive their illness.
 
The article mentions other reasons the mortality rate may be dropping:
 
[Researchers] say that factors outside of doctors’ control are also playing a role in driving down mortality. . . . Mask-wearing may be helping by reducing the initial dose of virus a person receives, thereby lessening the overall severity of illness for many patients. . . . Keeping hospitals below their maximum capacity also helps to increase survival rates. When cases surge and hospitals fill up, “staff are stretched, mistakes are made, it’s no one’s fault — it’s that the system isn’t built to operate near 100%”. . . 
 
This hardly means we’ve turned the corner on COVID-19, as one of the presidential candidates claims. A mortality rate of 7% is still high relative to other diseases. Serious illness is never a joy and even patients who survive COVID-19 sometimes suffer long-term effects.
 
In addition, two other numbers recently reported aren’t encouraging. The pandemic is causing significantly more deaths, either directly or indirectly, than are being reported:
 
In the most updated count to date, researchers at the Centers for Disease Control and Prevention have found that nearly 300,000 more people in the United States died from late January to early October this year compared to the average number of people who died in recent years. Just two-thirds of those deaths were counted as Covid-19 fatalities, highlighting how the official U.S. death count — now standing at about 220,000 [or 225,000] — is not fully inclusive [Stat].
 
One model predicts that the next four months will be especially bad in the US:
 
More than 511,000 lives could be lost by 28 February next year, modeling led by scientists from the University of Washington found.

This means that with cases surging in many states, particularly the upper Midwest, what appears to be a third major peak of coronavirus infections in the US could lead to nearly 300,000 people dying in just the next four months.

In fact the University of Washington warned that the situation will be even more disastrous if states continue to ease off on measures designed to restrict the spread of the virus, such as the shuttering of certain businesses and social distancing edicts. If states wind down such protections, the death toll could top 1 million people in America by 28 February, the UW study found [The Guardian].

Finally, the presidential candidate who doesn’t think we’ve turned the corner offered this timely reminder:

President Txxxx’s plan to beat COVID-19. 

Nine days.
