-sigh. Sometimes only part of what you say, and the intent of your convo with a journalist, comes through. This was that.

"‘Could be 10 cases, could be 100’: Alarming sign virus still in Qld
One of the state’s top virologists has warned Queenslanders"

...in a local paper.
I'm disappointed the worst scenario came out here instead of the other aspects - notably the uncertainty attached to sewage testing results - which we'd discussed. I got the impression this would not be an alarmist piece. My gut feeling was wrong.
So Queeanalders, to set the record straight, I also said that wastewater positive results could be from a boat, that it's publicly unclear how long sewage sits at a station before being treated. Also,
...a positive wastewater result could simply be from a known case in an isolation hotel which empties wastewater into the sampled catchment.
This piece has potential to induce fear. That can cause emotional harm. I try hard not to do that. I apologise to anyone who read the piece and got freaked out. You don't need to from these results.
And I simply won't comment to this reporter in the future.

To make it clear - @tibmolbiol, the company, did not "heavily cooperate" with me to write a 2002 review of real-time PCR. Katherine Arden and Andreas Nitsche leveraged their skillsets to create that lit review with me. Dr Nitsche was & is a scientist in his own right.
You can see some of Dr Nitsche's impressive research output here
The question of whether Dr Nitsche is still affiliated with TiB is strange but it's not one I can answer. I see nothing nefarious with him being, or not being, affiliated. TiB is a huge provider of fee-for-service oligos * kits around the world

Hey solar power Twitter...
Our household got a new inverter which shows us input/output via wifi (so yeah, I'm staring at it constantly)
When we turn everything off (still wifi & maybe 3 small standby devices) there still seems to be a ~500W from somewhere.
Where, how?
Thanks for the many answers. Will try a number of things tomorrow. There is also a 10min or so lag between action and the change showing up on the readout-perhaps I didn't wait long enough.
Okay, got it down to about 100-200W from small individual items; a list of small things, some of which we will get better at turning off at the wall 🙄
Water heater wasn't off in previous testing + there was a lag in the App's reporting. Isolation at fusebox to happen next.

The new version as promised (ver2).
It adds vaccines (at the end because gen1 won't simply fix everything) & tracing has been combined with the fast & sensitive testing slice.
I've combined hand & surface cleaning.
Constructive feedback welcome.
Version 2 also adds a slice for isolation & quarantine. The new Government Comms (includes education) & support slice reflect how essential these are to all of these interventions (especially if you're going into Iso & your livelihood is at risk) succeeding
I haven't added a "lockdown" slice although I don't see any other way to put the brakes on widespread & exponential rises in cases & hospitalizations without acknowledging that no intervention will lead to more deaths than lockdowns (unless there are studies that show otherwise?)

An interesting comparison between comments about Madrid on "herd immunity" in an article in June...& numbers today... ImageImageImage
I don't mean to belittle the suffering & harm occurring in Spain here - this is solely to point out how misleading it can be to read "most affected regions like Madrid may be close to reaching herd immunity" (quantamagazine.org/the-tricky-mat…)
There is clearly a new wave ripping through Madrid; which is in a state of emergenecy. And while deaths are not (yet) near the levels they were in Peak1 (great news), that may or may not change with time. Nonetheless, Madrid has more illness now than it had during Peak1 ImageImageImage

A little early in the year, nonetheless, there are fewer flu(+) samples around in the US than there were this time (Wk40) in 2019

Antiviral activity of an alcoholic hand disinfectant. Comparison of the in vitro suspension test with in vivo experiments on hands, and on individual fingertips.
[from 1983] sciencedirect.com/science/articl…
"The significance of 'spontaneous decay', in our view, is that it marks a qualitative difference between the 'reality' of hand disinfection and its model, the suspension test.
It also underlines the difference between enveloped and naked viruses in...
..the hand disinfection situation"

"As to the cause of 'spontaneous decay', one may speculate that the chemical milieu of the skin surface, e.g., pH or fatty acids, contributed to inactivating virions, predominantly those with a lipid-containing envelope.
In addition,..
