ICD-10 is really the heart of the matter. Earlier recommendations have asked doctors to encode corona death information using Pneumonia (J12.89) or Bronchitis (J20.8, J40) if positive test results are available, suffixed by B97.29 if authorized by the CDC to do so. We now appear to finally have the pneumonia encoded info thanks to NCHS. Hopefully govt will open source the bronchitis encoded reports too.

The good news from the recent report (https://data.cdc.gov/NCHS/Provisional-Death-Counts-for-Coron...) is that overall mortality in America these past few months, has actually been lower than previous years. The bad news is that we should prepare for the possibilty that mortality for the new coronavirus specifically could turn out to be much worse than many non-official sources online have speculated, and that what's happening in NYC is happening in a lot more places too. Correcting for software workarounds and verifying good accurate data takes time.
Did I understand correctly that there was two diagnostic codes for cause of death related to the coronavirus? One for "potentially related" to COVID-19, and one for "definitively caused by" COVID-19?
If so, how would this skew actual numbers reported by the WHO or CDC for cause of death?

Check out Table 4.
I guess it's an arms game in part.
I wonder whether sampling from sewage pumping units could be done. That might produce higher resolution data. But getting representative samples would be harder. You'd probably need to take large samples, mix, and subsample.

this is the second sewage testing paper I’ve read today. Why are these so incredibly interesting and fun to read when compared to the other testing documents I’ve read haha.
It was interesting because some organizations didn’t want to know that level of detail, which drugs were being used when, how many students came to school drunk etc. and all by sampling the sewage system regularly
> Of all the flavors trickling downstream, artificial vanilla dominates the sound, Keil said. For instance, the team found an average of about six milligrams of artificial vanilla per liter of water sampled.
> The region's sewage runoff contains more than 14 milligrams of vanilla per liter. This would be like spiking an Olympic-size swimming pool with approximately ten 4-ounce (113.4-gram) bottles of artificial vanilla.

It was meant as a prank, not an instruction manual.
> Studies have also shown that SARS-CoV-2 can appear in faeces within three days of infection, which is much sooner than the time taken for people to develop symptoms severe enough for them to seek hospital care—up to two weeks—and get an official diagnosis, says Tamar Kohn, an environmental virologist at the Swiss Federal Institute of Technology in Lausanne.
Still, that'd be a lot of samples to test.
The decomposition of wood creates vanillin, which I assume makes up most of what these folks found.
I see that some artificial vanillin is made from lignin, but I don't know whether natural wood decomposition creates vanillin. Do you have a reference for that?
Or... They test everyone's sewage independently and privacy-advocate groups cry foul because sewage (and garbage) are personal information and the city can't use it to discriminate or punish people!
Really the sewage issue is just proof that the system is broken on multiple layers. First off is sticking with the war on drugs when it is clear that fighting abstract concepts or inanimate objects is like getting drunk and boxing with a lamppost - you just look stupid and hurt yourself. Second the precedents and doctrines of 'in plain view' of discards including what is essentially legally required. They were done in an era where the data would be useless to the police even if they could process it. Third, for all of their new data the process isn't actually improving things on any level. Fourth they are running on tautologies enforcing because they must enforce not because they have any vision for an outcome or a connection between their actions and results beyond 'because it is their job'.
"Smart" toilet/sink/pipe + sewage testing = data

> vanillin was also detectèd as a product of wood degradation by some other wood destroying fungi.
The levels of vanillin in waterways (14mg per liter) are ridiculously high for human urine to be the sole source.
