Jon, Gary

 

Gary, the “White Van Approach” is not googlable because I invented it to tease 
the libertarians on the list.  The idea is that every contact of every case is 
scooped up on the street by a white van and popped into to a comfortable motel 
room at government expense until she/he can prove non-infection.  If they are a 
breadwinner or caregiver, their responsibilities are taken over by others.  
Such a policy would permit normal life to continue and would minimize cases 
Because it minimizes cases,  I don’t think Jon’s objection applies to it, 
right?  

 

The herd immunity approach is where we are headed now, although in a stumbling, 
bumbling way.   

 

If you read down in the article that Jon sends, it appears that the lung damage 
is reversible, although not fun to live through.  As an 82-year old, offered 
the choice (we 82 year olds are always offered the choice) I’ld probably opt 
for rehab.  

 

By the way, I am copying in below an extraordinary article from England about a 
doctor who claims that the epidemic was self limiting and about to be over.  I 
am copying it in because the original was behind a paywall.  I think this was 
the original Boris Johnson approach which I think is being tried out in Sweden 
and perhaps Brazil?  Havn’t looked at the numbers recently.

Sunetra Gupta: Covid-19 is on the way out


The author of the Oxford model defends her view that the virus has passed 
through the UK's population

It’s the biggest question in the world right now: is Covid-19 a deadly disease 
that only a small fraction of our populations have so far been exposed to? Or 
is it a much milder pandemic that a large percentage of people have already 
encountered and is already on its way out?

If Professor Neil Ferguson of Imperial College is the figurehead for the first 
opinion, then Sunetra Gupta, Professor of Theoretical Epidemiology at the 
University of Oxford, is the representative of the second. Her group at Oxford 
produced a  <https://www.ft.com/content/5ff6469a-6dd8-11ea-89df-41bea055720b> 
rival model to Ferguson’s back in March which speculated that as much as 50% of 
the population may already have been infected and the true Infection Fatality 
Rate may be as low as 0.1%.

Since then, we have seen various antibody studies around the world indicating a 
disappointingly small percentage of seroprevalence — the percentage of the 
population has the anti-Covid-19 antibody. It was starting to seem like 
Ferguson’s view was the one closer to the truth.

But, in her first major interview since the Oxford study was published in 
March, Professor Gupta is only more convinced that her original opinion was 
correct.

 
As she sees it, the antibody studies, although useful, do not indicate the true 
level of exposure or level of immunity. First, many of the antibody tests are 
“extremely unreliable” and rely on hard-to-achieve representative groups. But 
more important, many people who have been exposed to the virus will have other 
kinds of immunity that don’t show up on antibody tests — either for genetic 
reasons or the result of pre-existing immunities to related coronaviruses such 
as the common cold.

The implications of this are profound – it means that when we hear results from 
antibody tests (such as a forthcoming official UK Government study) the 
percentage who test positive for antibodies is not necessarily equal to the 
percentage who have immunity or resistance to the virus. The true number could 
be much higher.

Observing the very similar patterns of the epidemic across countries around the 
world has convinced Professor Gupta that it is this hidden immunity, more than 
lockdowns or government interventions, that offers the best explanation of the 
Covid-19 progression:

“In almost every context we’ve seen the epidemic grow, turn around and die away 
— almost like clockwork. Different countries have had different lockdown 
policies, and yet what we’ve observed is almost a uniform pattern of behaviour 
which is highly consistent with the SIR model. To me that suggests that much of 
the driving force here was due to the build-up of immunity. I think that’s a 
more parsimonious explanation than one which requires in every country for 
lockdown (or various degrees of lockdown, including no lockdown) to have had 
the same effect.”

Asked what her updated estimate for the Infection Fatality Rate is, Professor 
Gupta says, “I think that the epidemic has largely come and is on its way out 
in this country so I think it would be definitely less than 1 in 1000 and 
probably closer to 1 in 10,000.” That would be somewhere between 0.1% and 0.01%.

Professor Gupta also remains openly critical of the Government lockdown policy:

“The Government’s defence is that this [the Imperial College model] was a 
plausible worst case scenario. I agree it was a plausible — or at least a 
possible — worst case scenario. The question is, should we act on a possible 
worst case scenario, given the costs of lockdown? It seems to me that given 
that the costs of lockdown are mounting, that case is becoming more and more 
fragile.”

She recommends “a more rapid exit from lockdown based more on certain 
heuristics, like who is dying and what is happening to the death rates”. She 
does not believe that the R rate is a useful tool in making decisions about 
government policies, as an R rate is “principally dependent on how many people 
are immune” and we don’t have that information.

She believes that deaths are the only reliable measure, and that the number of 
cases should not even be presented as it is so reliant on the amount of testing 
being done.

She explains the flare-ups in places like New York, where the IFR seems to have 
been higher than 0.1%, through a combination of circumstances leading to 
unusually bad outbreaks, including the infection load and the layout of the 
population:

“When you have pockets of vulnerable people it might rip through those pockets 
in a way that it wouldn’t if the vulnerable people were more scattered within 
the general population.”

She believes that longer-term lockdown-style social distancing makes us more 
vulnerable, not less vulnerable, to infectious diseases, because it keeps 
people unprotected from pathogens:

“Remaining in a state of lockdown is extremely dangerous from the point of view 
of the vulnerability of the entire population to new pathogens. Effectively we 
used to live in a state approximating lockdown 100 years ago, and that was what 
created the conditions for the Spanish Flu to come in and kill 50m people.”

Commenting on the Government response to the virus, she suggests it erred on 
the side of over-reaction not under-reaction:

“I think there’s a chance we might have done better by doing nothing at all, or 
at least by doing something different, which would have been to pay attention 
to protecting the vulnerable, to have thought about protecting the vulnerable 
30 or 40 years ago when we started cutting hospital beds. The roots of this go 
a long, long way back.”

And she believes it is a “strong possibility” that if we return to full normal 
tomorrow — pubs, nightclubs, festivals — we would be fine, but accepts that is 
hard to prove with the current evidence:

“So what do we do? I think we weigh that strong possibility against the costs 
of lockdown. I think it is very dangerous to talk about lockdown without 
recognising the enormous costs that it has on other vulnerable sectors in the 
population.”

On the politics of the question, Professor Gupta is clear that she believes 
that lockdowns are an affront to progressive values:

“So I know there is a sort of libertarian argument for the release of lockdown, 
and I think it is unfortunate that those of us who feel we should think 
differently about lockdown have had our voices added to that libertarian 
harangue. But the truth is that lockdown is a luxury, and it’s a luxury that 
the middle classes are enjoying and higher income countries are enjoying at the 
expense of the poor, the vulnerable and less developed countries. It’s a very 
serious crisis.”

Cody, Nick, et al.

Part of my concern with a white van or relying on herd immunity approach
is the side-effect health risks associated with Covid-19. From a Johns
Hopkins article 
<https://www.hopkinsmedicine.org/health/conditions-and-diseases/coronavirus/what-coronavirus-does-to-the-lungs>
 :

"People who survive ARDS and recover from COVID-19 may have lasting pulmonary 
scarring."

In analogy with some arguments made about an individual's right to control
their personal data, individuals should have the right to control their own
health. When we volunteer to risk our future health, there is room for a
compensatory argument. Even if Covid-19 is like data in that it wants to be
free, we ought to recognize that such a sacrifice should be rewarded and with
full disclosure as to the potentially lifelong health risks.
