KERRYN PHELPS: Deliberate COVID infections present extreme dangers

I have a message for the people I am hearing lately who say they just want to catch COVID-19 to “get it over and done with”.

Some people are going as far as having “community immunity parties” like the chickenpox parties of the 1970s before a vaccine was developed. Back in the day, most children had mild chickenpox infections, but some suffered complications such as pneumonia or encephalitis and many went on to develop excruciating outbreaks of shingles in adulthood.

Trying to get COVID-19 “over and done with” is a Very. Bad. Idea. And here is why.

Firstly, don’t believe the line that Omicron is “mild”. Both Omicron and Delta variants are circulating currently and while you might be lucky to get a “mild” case, you might be one of the people who gets severe disease. We also know that COVID-19 can infiltrate your major organs, including your brain and heart and connective tissues, setting up long term inflammatory processes.

Even after a mild case of COVID-19, you can get long COVID, a persistent debilitating state with fatigue, brain fog, painful joints and muscles, heart problems and more.

Research is showing children have a higher risk of developing diabetes after COVID-19 infection. There is still so much we do not know, particularly the potential for long term effects on the brain or the heart or other organs ten or 20 years from now.

Think your vaccine will help you? Yes, it is now well-established that three doses of vaccine substantially reduce your risk of severe disease, hospitalisation and death. But “reduced risk” does not mean “no risk” and the converse of half of ICU admissions being for unvaccinated people is that half of ICU admissions are currently for vaccinated people.

And if you think being young and fit and healthy is an impenetrable shield of protection, think again. Even though it is “less likely” that you can become seriously ill, it happens — even if you are otherwise well and vaccinated.

“Getting it over and done with” also doesn’t get it over and done with. Data from the United Kingdom are now showing that people are getting the Omicron infection a second or third time. If your first encounter wasn’t too bad, there’s nothing to say the second or subsequent bouts will go easy on you.

Every new infection is an opportunity for the virus to infect more people. Even if your illness is “mild” and self-limiting, the Omicron variant is highly transmissible and the other people you infect may not be so fortunate. They may be unvaccinated children or people who are medically vulnerable who have not made the choice to become infected.

The people you infect may be emergency workers, first responders or the ones responsible for transporting foods or medicines and stocking the supermarket shelves, and we are seeing the first signs of what it means when large numbers of essential workers are not able to go to work.

Australia has seen over a million people infected with COVID-19, half of those on the past two months as safeguards were removed. 

We don’t really know the true numbers of infections because of the debacle with overloaded PCR testing and the poor planning for the availability of rapid antigen tests.

More infections in the community means more likelihood of a new variant emerging.

It also means more likelihood of our health system collapsing under the strain. This is not just about treating you if you have severe COVID illness, it also means you might have trouble getting an ambulance if you have an accident or a heart attack or a stroke, or the date of your necessary but elective surgery procedure is pushed out into the Never-Never. It also means difficulty having your routine preventive health checks done, or getting to see a dentist.

Healthcare workers are restrained from speaking out, but the messages we are hearing tell a story of a system on the brink. Healthcare workers need everyone to be doing their bit to reduce the load, not increase it.

And if you think “getting it over and done with” will give you an infinite free pass to an infection-free future, think again. We now know that immunity is likely to last a matter of months, not years. Immunity from vaccination or natural infection wanes over time, and will not prevent you from getting the infection again.

Be aware also that talk of the disease becoming “endemic” is not realistic. This is an epidemic infection which will continue to come in waves as new variants emerge.

Infection is not inevitable and it is not necessary, but there are no quick fixes. We need to use the tools we have to prevent transmission from one person to the next. Wear an N95 mask when you are not at home, get tested if you are a close contact, get a test and isolate if you are symptomatic, stay in isolation if your test is positive, avoid groups and crowds, work from home if you can, improve building ventilation, improve air quality, and install CO2 monitors. 

Taking the longer view means buying time for the medical researchers to develop safe and effective treatments and improved vaccines.

So how about instead of “getting it over and done with”, you take the longer view about protecting yourself, your family and friends, your community, healthcare workers, the health system and the economy.

Catching COVID

Here’s where (and how) you are most likely to catch COVID – new study

Two years into the pandemic, most of us are fed up. COVID case rates are higher than they’ve ever been and hospitalisation rates are once again rising rapidly in many countries.

Against this bleak picture, we yearn to get back to normal. We’d like to meet friends in a pub or have them over for dinner. We’d like our struggling business to thrive like it did before the pandemic. We’d like our children to return to their once-familiar routine of in-person schooling and after-school activities. We’d like to ride on a bus, sing in a choir, get back to the gym, or dance in a nightclub without fear of catching COVID.

Which of these activities is safe? And how safe exactly? These were the questions we sought to answer in our latest research.

SARS-CoV-2, the virus that causes COVID, spreads mainly by airborne transmission. So the key to preventing transmission is to understand how airborne particles behave, which requires knowledge from physics and chemistry.

Air is a fluid made up of invisible, rapidly and randomly moving molecules, so airborne particles disperse over time indoors, such as in a room or on a bus. An infected person may exhale particles containing the virus, and the closer you are to them, the more likely you are to inhale some virus-containing particles. But the longer the period you both spend in the room, the more spread out the virus will become. If you are outdoors, the space is almost infinite, so the virus doesn’t build up in the same way. However, someone can still transmit the virus if you’re close to them.

Viral particles can be emitted every time an infected person breathes, but especially if their breathing is deep (such as when exercising) or involves vocalisation (such as speaking or singing). While wearing a well-fitting mask reduces transmission because the mask blocks the release of virus, the unmasked infected person who sits quietly in a corner is much less likely to infect you than one who approaches you and starts a heated argument.

All variants of SARS-CoV-2 are equally airborne, but the chance of catching COVID depends on the transmissibility (or contagiousness) of the variant (delta was more contagious than previous variants, but omicron is more contagious still) and on how many people are currently infected (the prevalence of the disease). At the time of writing, more than 97% of COVID infections in the UK are omicron and one person in 15 is currently infected (prevalence 6.7%). While omicron appears more transmissible, it also seems to produce less severe illness, especially in vaccinated people.

Likelihood of becoming infected

In our study, we have quantified how the different influences on transmission change your risk of getting sick: viral factors (transmissibility/prevalence), people factors (masked/unmasked, exercising/sitting, vocalising/quiet) and air-quality factors (indoors/outdoors, big room/small room, crowded/uncrowded, ventilated/unventilated).

We did this by carefully studying empirical data on how many people became infected in superspreader events where key parameters, such as the room size, room occupancy and ventilation levels, were well-documented and by representing how transmission happens with a mathematical model.

The new chart, adapted from our paper and shown below, gives a percentage likelihood of becoming infected in different situations (you can make it bigger by clicking on it).

A surefire way to catch COVID is to do a combination of things that get you into the dark red cells in the table. For example:

  • Gather together with lots of people in an enclosed space with poor air quality, such as an under-ventilated gym, nightclub or school classroom
  • Do something strenuous or rowdy such as exercising, singing or shouting
  • Leave off your masks
  • Stay there for a long time.

To avoid catching COVID, try keeping in the green or amber spaces in the table. For example:

  • If you must meet other people, do so outdoors or in a space that’s well-ventilated or meet in a space where the ventilation is good and air quality is known
  • Keep the number of people to a minimum
  • Spend the minimum possible amount of time together
  • Don’t shout, sing or do heavy exercise
  • Wear high-quality, well-fitting masks from the time you enter the building to the time you leave.

While the chart gives an estimated figure for each situation, the actual risk will depend on the specific parameters, such as exactly how many people are in a room of what size. If you fancy putting in your own data for a particular setting and activity, you can try our COVID-19 Aerosol Transmission Estimator.

The RBA cannot target level and growth of income (Wonkish)

John Quiggin recently wrote:

The first step should be a re-ordering of the Reserve Bank’s objectives to focus primarily on full employment rather than price stability. One way to implement this would be to target the level and growth rate of nominal income

April 1, 2020

APRIL FOOLS?! That’s what I first thought.

The following is a remix of a comment Tom Hickey made at The Economist in 2012.

MMT proponents argue is that there is a difference between money created by fiscal deficits and money created by bank lending. When the government issues currency into non-government it does so through the Treasury directing its bank, RBA, to credit non-government deposit accounts, e. g., to pay for submarines  or to pay the jobseeker payment or age or disability pension. The transmission from reserves to bank deposits is direct and does not depend on bank lending. Moreover, since there is no liability corresponding to the assets created in non-government in crediting these bank accounts, deficit disbursements inject net financial assets into non-government. Conversely, bank lending nets to zero since each asset has a corresponding liability, so non-government net financial assets remain unchanged no matter how much banks lend.

The reason that Nominal GDP targeting (NGDP) will not work is the flawed notion of the transmission mechanism from reserves to spendable bank deposits. When the RBA buys financial assets of whatever type, it simply increases bank reserves. The erroneous presumption about transmission is that that banks lend against reserves or lend out reserves. Neither is the case, as MMT points out. Rather, bank lend against capital based on demand from creditworthy borrowers willing to pay a rate that is profitable enough for the bank to risk it’s capital against. Increasing bank reserves does not spur banking lending and it does not affect the factors banks take into consideration in lending.

From this is simple to see why NGDP through increasing bank reserves, e.g., via quantitative easing (QE), will not increase effective demand and spur increased investment to meet it. The transmission mechanism is bank lending, which is in abeyance, and increasing reserves will not increase it as the failure of QE has shown. Unless the RBA would buy real assets like houses instead of financial assets like mortgage backed securities (MBS), it cannot not inject net financial assets into non-government, and there is no reason to expect an increase in effective demand due to increased bank reserves.

Australia is now in-effect at ZIRP (the support rate), as is the UK, Canada and the US and Japan have been for some time as have many others. This has done nothing either. MMT predicted the failure of these monetary policies around the world. It is time for fiscal policy to step up to the crease.

Ed: Thankfully that is what we are seeing in these Coronavirus time.

Coronavirus (COVID-19), GetUp and the Job Guarantee

According to a new GetUp! campaign release:

COVID-19 has hit us hard – thousands of people have lost their jobs, millions more could follow.

But while private industries are forced to close, and many jobs will be unsafe for the foreseeable future – we need every pair of hands to help recover, rebuild and take care of each other.

The Government must institute a Federal Job Guarantee to coordinate the national recovery and connect unemployed people with meaningful, safe, and decently-paid work.

You may ask what jobs can we do with all the physical distancing we are doing?  Note my use of the word physical, not social.  Social distancing is what leads to extraordinary losses of support of all shapes and sizes and leads to a great deal of harm.

The GetUp release continues:

Everywhere you look there are opportunities to connect the untapped potential of people with the unmet needs of our communities.

We need more people than ever on our farms and in our warehouses. We need people on the other side of the phone when people seek health or Centrelink support. We need people who can prepare meals, and deliver them to those in self isolation.

The Victorian Government has just announced “Working for Victoria” – a proposal that could be replicated across all states and territories with immediate effect.

But we rapidly need the Federal Government to follow suit.

Bill Mitchell offers many suggestions of what type of MMT Job Guarantee jobs could be done whilst we fight the COVID-19 pandemic.  Bill writes:

Australia has just been ravaged by drought, bushfire and then flood – before the coronavirus hit.

There is so much depleted land, infrastructure and personal care services that are required arising not only from these natural disasters but also from years of austerity and outsources of public services.

There are tens of thousands of jobs that the Federal government could fund across the regional and urban space to help improve our society.

There will probably be a shortage of medical support staff. Thousands of jobs could be created to ease the load in the short-term on the depleted health care ranks.

The food harvest is facilitated in so small way by visiting ‘backpackers’.

For those workers in regional areas who are now unable to work because of the closures enforced by the government or by consumer boycotts (not going out anymore), the Government could help shift workers into the food harvesting sector for the time being while border controls prevent people from visiting and working.

And if we are to protect our aged members of the population, then we could ensure they are secure in their homes with adequate food and other supplies, are able to maintain their gardens (if they have them), and attend to other needs.

Thousands of jobs could serve this function for the time being. There would be no reason for such a person to take the risk of venturing to the supermarket, for example.

And what about the claims that these shifts cannot be facilitated quickly enough to avoid mass unemployment?

Well, I think I could retrain as a hospital orderly, for example, in a matter of hours or a few days at most, if I was required to.

The women who entered the factories in 1939 had no prior background. But productivity rose quickly.

So I advocate major public sector job creation to help workers adjust to the loss of their current jobs (while the crisis persists) and to provide a productive workforce to enhance our social offerings in terms of infrastructure and services.

The number of jobs that could be created to absorb those losing their jobs elsewhere, which would add social value, is limited only by our imaginations.

GetUp finishes their release by asking you to sign their petition and demand a Job Guarantee to give people dignified work and strengthen our society?

Australian Real Progressives endorses this petition and it can be found here: We Need a Job Guarantee!

There are no free-market capitalists in a foxhole

There is a famous saying that means something to the extent that there are ‘no atheists in a foxhole.’ Foxholes are the burrows used during wartime. Well, in the face of a potential global economic collapse, there are no free-market capitalists who suggest responding to the crisis by doing nothing.

None of the measures considered by the Australian government are anything like the free-market rhetoric we were hearing some months ago, particularly the desire to have a budget surplus. So the desire for their previous agenda never had substance to it. It was a smokescreen and an excuse for why they did not want to pursue what would be popular economic policies. But given a crisis lurks on the horizon, their hand is forced.

Why exactly do they do it? Why have a go at the unemployed etc?

We used to let markets keep to themselves for quite sometime when the West first embraced capitalism. Sure, there was protectionism in the form of Mercantilism as countries sought to accumulate gold against one another (keep in mind this was the old gold standard system), domestic economies were comparatively ‘free’ compared to what we have had since the Great Depression. The whirlwind of casino capitalism and stock market speculation in the ‘roaring twenties’ ultimately lead to the 1929 crash that would create the Great Depression, allow for the rise of Hitler, and ultimately WW2.

Since WW2 allowed for full employment as many countries embraced Keynes’ ideas, full employment policies would set the stage for the ‘golden age‘ that culminated in the stagflation of the 1970s. Since with full employment, labour was relatively more powerful than they were before, they could bid up wages in a way that Kalecki foresaw in his article ‘The Political Aspects of Full Employment’.

Unemployment became a policy tool to discipline labour and to avoid stagflation. That is why they do it. So the unemployed are the cost of ‘price stability.’ Keep people unemployed, avoid the economy booming too much, keep workers afraid and encourage them to demonise anyone who is lower than them on the economic ladder, and there’s your answer. That’s why they do it.

But during a time of crisis, the emperor has no clothes.
