Swmbo's aunt's partner died yesterday of cv. She got infected at hospital where she works and transmitted to her family.
She's utterly distraught. :unsure:

Can anyone explain how air pollution can be singled out as an aggravating factor in covid deaths when population density will also be high - and thus a higher viral load - in ''dirty'' areas?

(the quote below is from the Guardian Live)

12:44

Higher air pollution could be linked to increased deaths and cases of coronavirus in England, a preliminary study suggests.
An analysis by the Medical Research Council Toxicology Unit at Cambridge University compared regional data on total Covid-19 cases and deaths, against levels of three major air pollutants.

It is a respiratory disease, it's not that controversial, if hard to demonstrate. we also know air pollution hurts parts of the immune system. If it didn't matter we wouldn't have the 1.5 million letters or various people on here quite worried.

The viral load won't be the same everywhere in cities and ever changing whereas long term exposure to pollution will be more constant. The pollution maps of Italy which don't always correlate with population density are um interesting to say the least.

So sorry to hear about your loss.
It should't be happening at another time the current rate of workplace deaths and everyone would be up in arms.
But too many appear to be happy to turn a blind eye at this. Putting yourself at risk though cutting conners is one thing. But having to put yourself at risk though other peoples balls up is quite another.

New Zealand, by contrast, has been highly effective and has a prepared level of alerts which can be expected to be stepped through.

There are several reasons why NZ may have coped with this better than many countries.
One might be the fact that they have a robust Civil Defence organisation, primarily to deal with earthquakes and volcanic eruptions, but which probably was able to adapt quickly to the current situation.

Air pollution and population density don't correlate perfectly, so a statistical process like a Principal Components Analysis will be able to determine if the two are "aliases" in explaining covid mortality - in other words, if you could ignore air pollution and only include population density in a predictive model without the model being less accurate. So in terms of this video, it would be like finding that some PC was exactly population density and that adding a PC for air pollution didn't change the plot at all, that it accounts for zero variation:

It's actually like a situation shown in Tip 3 in this follow-up video where maths scores perfectly predict reading scores, but I'm not sure if it makes sense without its precursor:

That probably (hopefully!) won't be exactly what they're doing, but PCA is probably the best-known similar technique and so has better explanations available than some others.

Is this the strongest indication yet that airborne propagation is very significant? (article in French, but graphic in English) https://www.rtbf.be/info/societe/de...l-exemple-d-un-restaurant-chinois?id=10485461

Amazon France extends its sulk over not being allowed to sell non-essential items (and thereby poach even more sales from French businesses that are obeying the law), while it continues to circumvent the law by shipping French orders from its UK warehouses: https://www.cnet.com/news/amazon-fr...avirus-safety-dispute-workers-home-wednesday/ following from https://www.bnnbloomberg.ca/amazon-face-off-in-france-serves-as-worker-rights-test-case-1.1422791

Sure.

They had a plan, and executed it.

Rather than deciding Brexit ideology is more important than breathing.

PPE update...I've spent the day calling Trusts and filling in Central Procurement forms

Really calling the Trusts is hopeless. I'm always put through to someone in charge of the pencil budget by reception. Zero response from Central Purchasing.

It's frustrating because in addition to a v good surgical mask supplier who can do 50k per day, we've now got an N95 mask supplier who can do gazillions

I've registered with the four biggest care home companies but, guess what, no reply. It's an automated system, you can't talk to their Head of Purchasing or whoever

I can see how people get frustrated and give up
