Even though the credit card chip reader is good we are all still contronting the touchscreen.
I was at the DMV here in the ba area (still open even though we are in "lock down") and they kept everyone 6' apart (good) but overlooked the touch screens and the fingerprint scanners as vectors. These thinks are all a difficult learning curve no matter how obvious.
Lots to learn and lots of opportunities for infection control for the ingenious. And opportunities for the less than scrupulous.
It drives me nuts when the POS terminal takes NFC (Apple Pay, Google Pay, etc.) but you still have to touch it to sign or press "Credit" or whatever. I hate touching those things when there isn't a pandemic.
I know that some materials are supposed to be bacteriostatic like linoleum and copper. Are there viral-static materials? can they be used as screen covers etc? it would make life easier (and could make someone a lot of money right now).

I believe copper does a good job on most viruses but it's not instantaneous. SARS-CoV-2 can survive for 4 hours on copper.
I just went to the supermarket at around 10:45AM this morning. Almost all vegetables gone. Almost all of the meat gone (a couple of trays of sliced chicken breast). Still some fruit.
I didn't think I'd see perishables in this state. What I'm not sure about is this due to stockpiling (some stuff you can freeze) or is it simply that people are staying home and need to cook themselves and the "normal" supply levels are not enough.

I know for the butcher at the market Wednesday is kill day so Thursday he has the best selection. I'm not sure when the grocery store gets its produce trucked in but you could always ask. There's always more coming in.
The vendor who sells eggs told me she was asked by a customer if there would be eggs next week? She replied that as far as she knew the chickens were still laying eggs! 😉
Amazon have announced 100k new jobs in USA as people hunker down and order everything in. Does make me wonder if Amazon will end up being a major vector in the spread...
Here is a summation of the report from the Imperal College in London. There was a link to the full report from one of the moderators a few posts ago. This sums up the report in a few short pages. Hopefully Dr. Ferguson recovers and continues his important work....

Modelling available data, the team found that depending on the intensity of the interventions, combinations would result in one of two scenarios.
In the first scenario, they show that interventions could slow down the spread of the infection but would not completely interrupt its spread. They found this would reduce the demand on the healthcare system while protecting those most at risk of severe disease. Such epidemics are predicted to peak over a three to four-month period during the spring/summer.
In the second scenario, more intensive interventions could interrupt transmission and reduce case numbers to low levels. However, once these interventions are relaxed, case numbers are predicted to rise. This gives rise to lower case numbers, but the risk of a later epidemic in the winter months unless the interventions can be sustained.
The report details that for the first scenario (slowing the spread), the optimal policy would combine home isolation of cases, home quarantine and social distancing of those over 70 years. This could reduce the peak healthcare demand by two-thirds and reduce deaths by half. However, the resulting epidemic would still likely result in an estimated 250,000 deaths (UK #'s) and therefore overwhelm the health system (most notably intensive care units).
In the second scenario (suppressing the outbreak), the researchers show this is likely to require a combination of social distancing of the entire population, home isolation of cases and household quarantine of their family members (and possible school and university closure). The researchers explain that by closely monitoring disease trends it may be possible for these measures to be relaxed temporarily as things progress, but they will need to be rapidly re-introduced if/when case numbers rise. They add that the situation in China and South Korea in the coming weeks will help to inform this strategy further.

I was led to believe that the truck to restock came yesterday, but that may not have been true. I went back this evening to see if anything had changed during the day, nope. The lady at the deli said that they were closing two hours early to give enough time to do restocking of shelves for tomorrow, so maybe it is partially a manpower issue due to unprecedented demand. If the worst comes to the worst I can don a face mask and go to the local markets. I never like going there because of the crowds. At this point in time it's probably not a good place to go.
We aren't going to go hungry, but fresh meat and veggies was not something I was expecting to see sold out!
Tony.
They radiatate the vegetables but they should do the same now maybe for food packaging if not stocked at home from 10 days to stay prudent ?
So people should observe prudence when unpacking food when coocking for the meal ? I mean supply chain handing could be a vector?
As there is plastic packaging everywhere in the industry food from supermarkets, letters, little card box, etc I know spray the packagings before fridge them or stock them as I shop food every two weeks.
Maybe I' m just a paranoid fool more, but lacking of exact datas but the ones I gave above in a post I prefer to be prudent ... Dear prudence may kill less and hapyness is a warm gun said 4 young britanic guys in a same LP...

I read the first couple of pages, and, out of sheer morbid curiosity, ran a word check to check the frequency of usage of certain words and their forms.
Results:
fact - 0
evidence - 2
assume - 23
model - 11
predict - 21
And your point, w5jag?
It's not like we can run experiments on populations that we isolate and infect to build evidence-based descriptions. I would hope such egregiously unethical (to understate by a light year) tests as the Tuskegee Syphilis experiment would be clear enough that any such analyses of an emergent disease are going to be models.
Everything being run is based on the early numbers coming from anywhere epidemiologists can get their hands on, which are undersampled and imperfect. Then they're using models trained from the data built up from most every disease breakout they have good data from. You modulate the infection rate and this is what you get. How you modulate infection rate is a sociological question, and an experiment in how human populations behave. Similarly, looking at data from prior epidemics and pandemics for clues about what does/doesn't work gives clear directions on how we should move forward.

I regret looking that up now!
Is there any test for susceptibility to Sepsis? From my ignorance this appears to be triggered by the infection in some cases and is the primary cause of death?
Bill--let me give a crack at the sepsis question.
Biologically, sepsis is an infection of the blood/tissue by foreign organisms (we don't use sepsis for viral infections) which leads to, more or less, multi-organ failure/dysfunction. Co-infection is a huge risk and makes bad things worse. Simplistic mechanism is:
1.) You are CONSTANTLY fighting infectious diseases of some sort or another.
2.) Fortunately, most of us are quite adept at managing these invaders without even knowing it's happening. Yay immune system!
3.) One disease breaks through, and your immune system's resources essentially respond to the threat according to its prevalence in the body (this is a HUGE simplification, and I'm sure Sean/others will be able to describe it better/more correctly)
4.) With the immune system tied up, other infections have a chance to take root. Almost a flanking maneuver in the great battle to keep us dying from a litany of diseases. This process is heavily modulated by treatment plans as well.
5.) These other infections may ultimately prove fatal, so a primary cause of death would be whole shebang, even if it's recorded as something like "COVID-19 with ____ co-infection"

Ah ok. I've read a couple of articles that suggest that the body is overeacting in some cases to COVID-19 and killing itself, but in journalistic style seems to have coflated that with sepsis.
I do find it fascinating how many of our symbiotes are actually joining in the fight in some cases. We are after all just a giant walking food source for the population that lives on and in us.

Cytokine storms from an immune overreaction to an infectious agent are extremely dangerous, and seem to be one major, fatal, trajectory COVID-19 takes. They aren't necessarily uncommon, either, but I don't believe are mechanistically tied to sepsis? Provide additional opportunities for another foreign body to take hold, sure.
Caveat--reserve every right to be dead wrong about this. I am still a (not so) humble EE at the end of the day. 🙂

Well, every cloud has a silver lining; The Eurovision song contest has been cancelled.
not a big loss if you ask me 😀

So death comminh from autoimun behavior ???

This is an old joke; to paraphrase Chris Rock, only the best rappers get shot.
