On day 6. Yesterday I felt good (under the circumstances that is), muscles just don't recover like they should and the regular energy still isn't there but I still haven't had coughs, breathing is more like normal and lungs feel fine. Today I lost most of my taste, smell and when I tried to answer the phone I realized my voice is almost gone. I will try do stuff that makes my pulse go up a bit so i can tell how I really feel.

Get tested? They don't do test on people that are outside vulnerable groups, don't need hospital help or handle vulnerable people. Besides, I lack a car so can't get there on my own. The rule for people like me is, stay isolated and if you start feeling bad, call for phone support, if it urgent, call 112. For statistics they check for people needing hospital help and intensive care.

Articles are a week old, I'm getting these from another forum I read, but thought they were interesting nonetheless. https://talkingpointsmemo.com/news/iceland-testing-coronavirus-success Iceland has confirmed 1,799 cases of the virus, but just 10 people have died. The number of new COVID-19 cases each day has fallen from 106 at the peak of the outbreak to single digits — even, on some days, zero.
“I didn’t expect the recovery to be this fast,” said Iceland’s chief epidemiologist, Thorolfur Gudnason.
Iceland’s success is partly testament to its tiny population — just 360,000 people. But it also reflects decisive action by authorities, who used a rigorous policy of testing and tracking to find and isolate infected people, even when they had no symptoms. Associated Press: US to rein in flood of virus blood tests after lax oversightWASHINGTON (AP) — U.S. regulators Monday pulled back a decision that allowed scores of coronavirus blood tests to hit the market without first providing proof that they worked. The Food and Drug Administration said it took the action because some sellers have made false claims about the tests and their accuracy. Under pressure to increase testing options, the FDA in March essentially allowed companies to begin selling tests as long as they notified the agency of their plans and provided disclaimers, including that they were not FDA approved. The policy was intended to allow “flexibility” needed to quickly ramp up production, officials said. “However, flexibility never meant we would allow fraud,” Dr. Anand Shah, an FDA deputy commissioner, said in a statement. “We unfortunately see unscrupulous actors marketing fraudulent test kits and using the pandemic as an opportunity to take advantage of Americans.”

Who would have thought that an agency created to make sure people weren't selling literal poison to consumers as miracle cures would then be needed to regulate companies selling utter lies to people in desperate need?

Another randomized double-blind placebo-controlled trial of remdesivir, this time at ten hospitals in Wuhan, China, published in The Lancet: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)31022-9/fulltextUnfortunately the results of this trial did not show any statistically significant differences in the primary outcomes measured: Our trial found that intravenous remdesivir did not significantly improve the time to clinical improvement, mortality, or time to clearance of virus in patients with serious COVID-19 compared with placebo.

Day 7. So I suppose that was the mild version, lungs stayed intact, no crazy inflammation or anything, no horror story about lacking oxygen or other severe illness. Its weird feeling ill and you can't really point at something that is really wrong with you, regular flu or cold is really obvious but this one felt out of place. I don't want to know how it feels like when this shit hits the lungs.

Glad to hear that you are better. It's too bad they are not interested in testing you for purposes of contract tracing.

A pre-print (non-peer reviewed) paper was uploaded today that claims that if you take into account individual variations in susceptibility or exposure to SARS-CoV-2, the percentage of people that needs to be infected (and recover or die) before the virus stops spreading is smaller than if you assume everybody has the same susceptibility and exposure chances. Individual variation in susceptibility or exposure to SARS-CoV-2 lowers the herd immunity thresholdI'm still trying to understand their argument but I believe what they are claiming conceptually is that: 1. People who are susceptible to being infected will get it sooner rather than later 2. People who are "connected" will get it sooner rather than later 3. Once the above two populations have been infected and recovered (or dead) those that remain are either less likely to be infected or are essentially hiding so there's not enough less "fuel" around for the virus to keep spreading, thereby lowering the percentage of population that needs to be infected before herd immunity kicks in.

On it's face, it's bullshit, by their own assumptions the population of "susceptible" needs to quickly die or recover without infecting the "vulnerable". It's the "herd immunity" argument with extra pixie dust.

Another pre-print paper that also claims that for COVID-19 we won't need to reach the classical, vaccine-based herd immunity percentages to reach herd immunity. The disease-induced herd immunity level for Covid-19 is substantially lower than the classical herd immunity levelTheir model is different than the previous one but it's also based on the assumption that the disease is spreading through a heterogeneous population rather than a homogeneous one. In this paper they group people by age and then assume each age group has a different amount of "activity"/contact. So the younger more active population is infected sooner than the younger or older less active populations which again means the herd immunity % doesn't need to be as high. Interview with one of the authors, Tom Britton, about the paper: Ny kalkyl: Stockholm kan nå flockimmunitet i juni (New calculation: Stockholm can reach herd immunity in June) It's in Swedish but Google Translate seems to do a good job translating.

Need a proper antibodies tests so that they can do proper testing to see who had it in stockholm, until then any calculation is just throwing darts at random.

Yeah - when part of the assumptions are that people are hiding from the virus, it doesn't pan out.

Yes I don’t understand the math but I assume both models are assuming people are mixing more freely than they are in stay at home conditions though it’s not clear if Sweden matches that or if they are mixing enough for either model to apply. But without enough mixing you end in a situation like South Korea right now where some “super spreaders” have been isolating and once you let them mingle again you start back up the spread of infections. So you need to get those people infected early for the overall herd immunity threshold to drop if I understand these models correctly.

To simplify, they are saying the potential super-spreaders will catch it early, so the potential R0 will drop and the herd immunity threshold will be lower.
There may be something to that, but they are not really understanding the underlying graph theory as applied to social spaces (this is very definitely in my wheelhouse), and as a result are overstating the effect by an order of magnitude. They're saying it reduces the threshold from 80% to 30%, the reality is more like 80% to 75%.
tldr: Hyperconnected nodes are generally on the shortest arbitrary paths across a graph, but real social graphs are highly redundant. Taking out the shortest paths to infection does not remove all paths to infection.

Uh, their model, using their default values. seems to disprove their thesis. So I'm not sure what the point of including that was.
Fortunately for us non-Swedes, Sweden continues to test whether or not you can develop herd immunity to COVID-19 on a real life population (sadly for Swedes, their own), so we should know by the end of Summer whether or not that's possible, unless they give up and lock down.
Edit: clarification

It has some problems with how it is written, but the default is meant to show how herd immunity works. As you play with the sliders as they discuss through it, you see the problems.

Yeah still don't see the problem. Increasing R0 decreases the number of days to reach herd immunity (obviously that may overwhelm hospitals but they don't model that). Shortening immunity duration by *a lot* does drag things out, potentially indefinitely, and while that is still an unknown given what we know from other coronaviruses it's probably not *that* short.

Shortening immunity duration by *a lot* does drag things out, potentially indefinitely, and while that is still an unknown given what we know from other coronaviruses it's probably not *that* short.
Their fictitious disease, labeled as Fictitious, using the default sliders hits herd immunity threshold in about 50 days. It is not a simulation of COVID 19. They then explain herd immunity, etc.... Then they say, why is herd immunity not a good solution for COVID 19? 1.) This is a highly contagious disease. That pushed to a higher percentage of the population needing to get it before there is a chance of herd immunity - and that chance is contingent (see below). 2.) We don't know the extent to which antibodies help us. So far, the reports of reinfection seem to be situations in which the original infection has not left the body and the positive tests down the road after being free of symptoms may be evidence of resurgence, not reinfection. However, we do not know how quickly this RNA virus will mutate. We do not know if our bodies complete kill off the virus in our bodies. And we do not know if the virus is being killed off enough to keep us from getting symptoms again, but is leaving us capable of transmission (or, at least, leaving a percentage of the population). The scariest version of this concern would be for our immunity to wear off before we reach herd immunity. That is unlikely in this case given the rate this thing spreads... unless we're prolonging the spread by flattening the curve. A lot is unknown here, although there is reason to be positive that this is going to be something where getting it once gives you protection for a while from being sick again. 3.) Finally - due to the highly contagious nature of this bug, the amount of people needed to reach herd immunity is high. Assuming we get there before people lose their protection from transmission / getting symptoms, we'll have essentially the entire population have it. As there is little we can do for the people that get it and get very sick, that could mean millions die in the US over a few cycles. And when you factor in that the high estimate for percentage of population infected based upon studies in NY, a hotspot, is 21% and the herd immunity requirement is likely between 70 and 90%... We are going to have more rounds until an effective vaccine is distributed enough to push us across the herd immunity threshold. If you play with the sliders, their model says that we'd only be in a danger of perpetual infection (where we lose immunity before the virus disappears) if we lost immunity over a 3 or 4 month period. However, this does not factor in the nuances of the virus resurfacing. For example, if we lose immunity after a year, and there are people that sneezed on a frozen package and open it a year later, and get just enough virus and bad luck combined, we could have a new patient zero and no immunity in the general population. So herd immunity is unlikely to help us much because most people will get sick before the virus burns itself out - and there is a chance it could fail to eradicate the virus entirely for several reasons and that we could lose immunity before it resurfaces. The final lines: So let’s go back to that 70 percent herd immunity threshold. If the fatality rate is around 0.5 percent and 70 percent of Americans have to get sick before their immunity starts protecting others, that means more than 1.1 million people would die. In New York, even having 21 percent of the population exposed, if that serological survey is accurate, has overrun hospitals and led to the death of one in every 400 New Yorkers, while the vast majority of the population remains susceptible.
“That’s the cost of getting to 20 percent,” said Emma Hodcroft, a postdoctoral epidemiology researcher at the University of Basel in Switzerland. “It really illustrates the price you’re going to pay if you want to get up to the 60 percent or 70 percent that you’ll need for herd immunity, and I hope it really illustrates why that just isn’t a feasible plan.”

I was just waiting for my body to go back to normal and thought of things I normally do after being hit by a regular flu or common cold and make sure to not do that stupid shit this time. My voice, sense of taste and smell is slowly recovering.
