Contact tracing is not needed - identify the people at high risk and protect them from the virus. People at low risk should be expected to circulate the virus and develop immunity. Contract tracing among low risk defeats the purpose.

If we're ever going to get our lives back, and not be on indefinite timeline of "maybe there will be a highly effective vaccine" we actually need the virus to circulate among people who can safely get it, get over it, make antibodies which historically - before the advent of highly effective vaccines - is how pandemics ended.

Total isolation policies prevent broad population immunity. We know from decades of medical science that the population develops immunity while acquiring antibodies.

Well, sure. That is what has been happening anyway. But it's hard to keep the low risk people away from the high risk people all of the time. Or are you really not going to ever visit grandma again, potentially for years?

So, even if you're low risk, it helps to know if you've been exposed so you can isolate yourself and protect the high risk people.

As someone in a low risk group (I’m 30 without co-morbidities), the risk of surviving but having an awful time is highly underrated. That’s part of why I stay at home now, I’d prefer to not experience that.

General pontifications aside, I’m sorry that you’re sick, and hope that you recover quickly and cleanly.

I think I have it. Going on 4th week with mild symptoms (severely itchy hands/arms, constant headache, muscle fatigue recently) that don't match published ones. I was probably infected going to grocer 6 weeks ago and took 2 weeks to manifest. The itch/red spots move around like every 8 hours ( I don't scratch it). What happened to you? Did it get in your lungs? What does a relapse behave like? I'm just trying to figure out what might happen.

There's no evidence of that. There are some very occasional skin conditions associated with COVID but they don't don't sound much like this.

This absolutely does not work.

In Australia we tried to keep aged care homes isolated, and it was catastrophic - something like 25% of deaths were from a couple of cases that were undetected and made it into aged care homes.

In Sweden this was explicitly their plan and here's what happened:

“It’s very difficult to keep the disease away from there,” he said. “Even if we are doing our best, it’s obviously not enough.”

But he said: “We are not putting anybody’s lives above everybody else’s lives – that’s not the way we’re working.”

Tegnell said in late April that at least half of the country’s deaths had been in nursing homes.

“We really thought our elderly homes would be much better at keeping this disease outside of them then they have actually been,” he told Noah

As someone working with large health non profits on COVID tools, whose head is deep into the reporting and news around it, and who has 3 school age kids in NYC, I am of the opinion that there is no low risk population, no "safe to get it" group.

There are groups where symptomatic incidence is lower. Sure. But JFC some of those symptomatic cases are awful, with lifelong impact.

Someone used the Russian Roulette metaphor early on and it continues to resonate with me. We see over and over again surprising case histories all across the demographic, age, and health history map. Too many that are completely unexpected and for which there are presently no predictive metrics.

We are slowly learning more about what this virus can do, and we have a sense of what it will do when presented with a known vulnerable population. It is remorseless.

But even for "low risk" populations it is exactly like Russian Roulette. You and 9 others might be at the peak of known clinical health measurements and it may leave those others unscathed- that we know of- while it will destroy your lungs or your liver or cause you to have a stroke.

With all respect to the goal of broad population immunity, for my family- we stay carefully isolated and adopt all defensive protocols, we wait for a vaccine, and we advocate for govt entities to provide the liquidity to keep safely running the various life sustaining machines that our interdependent world depends on.

> we advocate for govt entities to provide the liquidity to keep safely running the various life sustaining machines that our interdependent world depends on.

There is a very real risk that won't work. If it worked, why would we only do it in emergencies? Government may as well provide funding for essential services all the time.

The government would simply be handing out money to the people working in essential services who are doing real (and quite risky, apparently) work while. You would be receiving the benefits without doing anything. That is almost the 'paid in exposure' meme that artists have to put up with.

The economic system is crafty, it will figure out that there is dead weight somewhere and start to optimise around it. This might be unprecedented so the failure modes are beyond me - but it won't be pretty if it goes on like that. Gluts would probably not be the end of the world but severe shortages are possible.

In Australia we had an official government inquiry into why the price of milk was so persistently low. No other problems. Just low milk prices. That is what happens when a free markets run the food delivery system. That won't happen if the government steps in and starts making decisions about what is fair and who needs which items.

Russian roulette has a much higher risk than a coronavirus infection.

If you're ignoring the rates then you might as well say that driving to work is like Russian roulette.

Do you have any figures (graphs ideal) for the lung damage (or other long term health effects) distributions?

Food is essential. Water and electricity are essential. Going to the movies or eating out is nice but certainly not essential. There's nothing clueless about wanting to keep the essentials running while limiting the non-essentials.

I don't pretend to know where the correct balance lies between injecting liquidity and reopening things but there's certainly nothing clueless about doing so in a calculated manner.

There absolutely is essential work, and at this time, until we know more, until we have both some predictive power and some reliable treatments at the individual level, this work is hazardous, barely indistinguishable from war. Those doing that work should have all of the support and benefits that come from choosing that sacrifice, putting themselves in harm's way. That we are not treating those roles that way is barbaric.

This is a ridiculous comment, totally disconnected from reality. The risk of a seriously bad outcome from SARS-CoV-2 infection are far less than 1/6 (Russian Roulette) for most people. Hiding in our homes until a vaccine appears at some unknown point in the future is obviously not a viable strategy.

If we drive the economy into another Great Depression that will kill many people as well. Federal government liquidity injections are not a solution. At some point if people aren't out working to create value then society will disintegrate.

Re:Nearly 40% of Icelanders are using a Covid app, but it ha... by jonahbenton on Saturday May 16, 2020 @08:13PM (#23208289)
Appreciate your opinion, and agree the ratio isn't 1/6, but it's not de minimus and there is no safe population.

There is essential work, those jobs are wartime/highly hazardous jobs, and deserve all of the support and gear that actual war fighters get. That isn't happening.

Finally, Fed liquidity is a tool with far greater power than we are utilizing. To not exercise that power, and to not equip hazard roles- is simply barbaric.

Good luck and good health to you.

Re:Nearly 40% of Icelanders are using a Covid app, but it ha... by jonahbenton on Sunday May 17, 2020 @08:44PM (#23216995)
No. In NYC, in the teen and pre-teen set, we have thousands of confirmed/symptomatic infections, hundreds of hospitalizations, dozens of deaths, and dozens of strange case histories. That's what's reported. I speculate based on anecdotal conversations with other parents there is much still unknown/unreported.

We don't have a model for how to understand exposure and immunity dynamics for this population. My personal sense/estimate is that between 10% and 20% of the child population has been sufficiently "exposed" to now be considered "safe" but I would not bet my children's lives on that measure. I am eagerly awaiting the day I can get my kids tested for antibodies, but even if they test positive I can't consider them or us to be "safe" until we know a whole lot more.

At any rate, given just the reported numbers, a conservative back of the envelope risk-of-significant-impact from "exposure" in the teen/pre-teen set is somewhere between 1 in 1,000 and 1 in 10,000.

Re:Nearly 40% of Icelanders are using a Covid app, but it ha... by concordDance on Monday May 18, 2020 @02:52AM (#23219168)
Your statement is contradicted by this page here: https://www.worldometers.info/coronavirus/coronavirus-age-se...

Which says there been three coronavirus related teen+preteen deaths with no underlying conditions (all of which were teens IIRC) in NYC and another 6 with underlying conditions.

Do you have a more reliable source?

Also, 1 in 1000 is close to the estimated infection fatality rate for the general population (estimated between 0.1% and 0.5% normally) and kids are supposed to be a couple of orders of magnitude less at risk than the population average. So your numbers all seem utter nonesense to me.

I've never even heard of a preteen death of covid.

We don't have evidence due to disease being so new, but there's enough reason to suspect we'll develop at least short term neutralizing immunity.

But yes, caution is necessary. We don't have enough evidence to push forward a national strategy that's based on people developing immunity without a vaccine.

Here's WHO's statement on this matter:

https://www.who.int/news-room/commentaries/detail/immunity-p...

"Herd immunity" without a vaccine, as a strategy, is equivalent with doing nothing and let the virus wreak havoc on the population.

What's worrisome is that some people are testing positive again, after being diagnosed as positive. Crew on the CVN-71 Roosevelt have tested positive, been quarantined for 14 days, then tested negative twice (two days apart), but then still testing positive a few days later.[1]

The possible scenarios for this I can come up with are:

1. No immunity after initial infection

2. Bad test methodology (contamination etc)

3. Bad tests. The article doesn't mention the test type, so perhaps they were initially misdiagnosed (false positive), then infected upon return to the ship. The implication from this would be that the virus is still prevalent in the crew on board the Roosevelt...

In South Korea, they discovered that all of the many potential reinfections they had detected were due to faulty (overly sensitive) tests. There are no confirmed cases of reinfection and many thousands of people on 'front line' jobs who have recovered form the disease, returned to work and never been reinfected. In a study done on monkeys, scientists were unable to achieve reinfection.

Risk vs reward. If there is immunity, then developing herd immunity sooner rather than later is important (even more so if there's immunity but it's only short-term). If there's no immunity, we're, excuse the expression, fucked anyhow.

Can vaccines even be developed if there's no natural immunity?

If there is short term immunity yes (diphteria, tetanos is an example, polio too).

Being exposed to the same antigen while you have an immunity should reactivate this immunity, that's a reason why a "herd immunity" tactic could work, at least for a time

However if the natural immunity w/o reactivation only last a year or less, you will end up with a new outbreak at the end of the period. And if the immunity period is shorter than the recuperation one, you will have a virus that will be a lot more lethal.

Look at the bigger picture. In today's immensely innovative world there will almost certainly be a vaccine or anti-viral or some effective treatment within a year or two.

The goal for those of us who are lucky enough (in normal times it can be a curse) to live on an island is not to hide out forever - it's to hide out until that treatment is available.

How clever. Yes, we have high confidence that hydroxychloroquine, azithromycin and zinc are very helpful at treating it.

My intention wasn't to demean but rather to provide a clear and understandable message for other readers who might lack the scientific background to critically evaluate your claims. I was also hoping that you'd take the hint that perhaps you lack the requisite background knowledge to commentate usefully on the topic.

The first two links are the ones with unexplainable results (to put it charitably) by the now infamous Dr. Raoult. The third one is a review which identifies previous successes in vitro and argues for further clinical trials to take place. In vitro studies are useful for identifying drug candidates to test but say absolutely nothing about whether something will work in practice.

Meanwhile, the link I provided in my previous comment neatly summarizes the current clinical data on the topic. In a nutshell, hydroxychloroquine does not appear to be particularly useful for treating hospitalized patients. It might or might not have some mild beneficial effects and it definitely has serious safety concerns; the arrival of additional clinical trial data in the near future should hopefully give us a more complete picture.

I stress again that there are currently no known effective treatments.
