‘Tis The Season To…..Mask Up Again??

"It's a bug hunt!"

-Private Hudson, in “Aliens”

"Influenza-like illnesses" are increasing at an alarming rate across the country. Yup, ‘tis the season for respiratory diseases and we have more than one to worry about. In years past we mostly worried only about the flu and, sometimes as an afterthought, colds, which aren’t of much concern. But in late 2019, a brand new and very weird bug appeared on the scene, SARS-CoV-2 that caused COVID. It seems that the bug and disease will be an annual guest from now on. This year, we also see a surge of a third bad bug, respiratory syncytial virus, or RSV. All these viruses cause what have been collectively labeled “flu-like illnesses” and together they seem to be worse this year than recent years. The CDC reports that hospitalizations for flu-like illnesses have been steadily rising and that the peak is still to come.

As a result, we are beginning to see increasing reports of a return to local mask mandates. In my own community of Madison, Wisconsin, two major health networks just announced their return, like a bad TV rerun. This includes the University of Wisconsin Health network, where I receive health care. Glad I kept a few masks on hand. What’s in your glove compartment?

I also have read where some grocery stores are now requiring masks. Some stores only require masks on certain days of the week so that customers can select to shop on mask-required vs mask-optional days. Some colleges and large companies reportedly also are beginning to require masks again. So far these mandates are very local and are not a national phenomenon. It is feasible that mask mandates in public spaces and especially for travel could increase if infections and hospitalizations get more serious.

As I often say in these blog posts, “we will see.”

Why is the flu and RSV, which have been around almost forever now causing more than their usual problems? A hint was presented in a blog post I published about a year-and-a-half ago, “What Happened To The Flu And Other Respiratory Diseases?”  In that apparently prescient post, I reported that the world had seen a huge reduction of all infectious respiratory diseases due to the protective non-pharmaceutical interventions (masking, sanitation, isolation, quarantines, closings, etc.) designed to physically protect people from the new coronavirus. They were so effective that some strains of other common infectious viruses are thought to have gone extinct!

That is great news! But, it also means that the world also missed its regular natural booster of common bugs and our herd immunity to them waned. Our youngest were never exposed to those bugs and the rest of us became less resistant to future exposure and that future is now. We are now paying the piper for that lapse in a “bug boost.” Hence, flu and RSV temporarily are having their way with us and enjoying it. At least they are not nearly as nasty as the coronavirus initially was and still could be with a couple of insouciant genetic tweaks.

“Influenza-like illness,” is a catch-all term coined by the CDC to corral COVID and the other two viral diseases. Together, the three have reached an epidemic point in the US and other places across much of the world. The Figure below shows that the US epidemic is currently hitting Southern States the hardest, but expect it to migrate Northward in the next few weeks.

What do the different colors in the Figure mean on a practical level? I can offer one anecdotal example. According to the map, New Jersey, while not a Southern State, still is being hit hard. A family doc wrote about a week ago that all the hospitals in his health system are at capacity. He was unable to send a patient to the preferred ER because its hospital was full due COVID, flu and RSV cases. And the patients with these flu-like respiratory infections who were filling the beds were not necessarily elderly. Most are in their 40’s-50’s. Unsurprisingly, the hospitals and clinics in his health system again require masks. Their staffing is becoming a critical issue as providers also become ill and turn into patients. This is becoming too reminiscent of the early stages of the COVID onslaught when hospitals where overwhelmed and medical personnel were dropping like flies. So far, this experience is sporadic across the US. But, it is becoming concerning.

Outpatient Respiratory Illness Activity Map Determined by Data Reported to ILINet

This system monitors visits for respiratory illness that includes fever plus a cough or sore throat, also referred to as ILI, not laboratory confirmed influenza and may capture patient visits due to other respiratory pathogens that cause similar symptoms. From the CDC.

The incidence of RSV is high. RSV hospitalizations have increased 60% nationwide over the past four weeks. A couple of deaths in children have been reported in my state. The vaccine for RSV is brand new this year and recommended for people over 65 and for kids; i.e., those at highest risk for severe disease. It definitely is worth it.

Flu is moderate right now, but expect it to soon blossom. Hospitalizations among all age groups increased by 200% for influenza in the past four weeks but still remain below Covid-19 and RSV hospitalizations. For now. They are expected to increase as the peak flu season has yet to arrive.

And then there is our relatively new friend, COVID. On a national level, COVID virus transmission is “very high.” After the post-Thanksgiving surge, as determined by monitoring viral loads in wastewater samples (“take-your-kids-to-work” days in that profession must be fun!), virus levels plateaued. But expect another sharp rise after the Christmas/New Year’s holidays. We have consistently seen this pattern in previous years.

Cov-2 is one of the most mutable viruses that the world has inflicted on us. That means we are constantly seen new variants arising. Surprise, the Omicron subvariant JN.1 is coming onto the scene. It’s the spawn of variant BA.2.86, which was discovered over the summer and was concerning because it came out of nowhere with a whopping 35 mutations in the spike protein (the more mutations, the greater the chance for another very nasty bug). While BA.2.86 caused a comparatively mild disease, it quickly mutated to JN.1 with just an additional single change in the spike protein that made it much more infectious, but it still remains fairly mild. With just one mutation, it became the fastest-spreading CoV-2 variant in the past two years. With all its changes, JN.1 is so different from its Omicron grandparent that there is considerable scientific debate about whether JN.1 should be given its own Greek letter designation, Pi. A weighty debate indeed.

But, a bigger question is whether COVID hospitalizations will follow wastewater sampling trends that show JN.1 (or Pi) viral levels surging through the world, especially in the US where vaccination rates are low. It is concerning that the UK and Singapore, which have high vaccination rates, are now seeing a steep increase in hospitalizations due to JN.1 (or Pi). So why not expect the same or even worse in the undervaxed US? Last week, the CDC warned about such a potentially huge impact due to the wretched combination of low US vax rates and the highly infectious JN.1 (or Pi) virus. As Private Hudson (aka Bill Paxton) in the movie Aliens might say, thanks to the antivaxers, “Game over, man! Game over!”

Also of new concern is that some scientists are now beginning to believe that COVID infection could be damaging our immune systems. If true, that could make infected people even more vulnerable to the other bugs out there such as flu, RSV, and others including bacteria and fungi. COVID could also cause immune dysregulation leading to new-onset autoimmune diseases. So get your COVID vaccines! They can protect you against illness beyond COVID!!

Finally, another concern is that the rapid home tests for COVID are proving to be only 30% reliable very early after infection before symptoms start. In other words, if you believe you have been exposed to COVID, but your home test comes up negative, don’t necessarily believe it. Retest yourself 24, or preferably 48 hours later or when you show symptoms like a fever, cough, etc. If that second test also is negative, you have pretty good confidence you are COVID free and have some other bug.

The pragmatic bottom line. There is a lot of coughing, sneezing and other respiratory distress going around, and it will increase in coming cold weeks as we bundle up and crowd around others indoors. To improve your odds of staying healthy, remember these things:

• Limit your time around indoor crowds.
• If you have indoor gatherings, crack your windows and bring out the fans to increase air circulation and air exchange with the outdoors. There is very good evidence that good ventilation really matters and that the amount of viruses we breathe in makes a big difference in terms of whether we get sick and how sick we get. It is worth a few extra dollars on the heating or electricity bill to avoid nasty illness.
• Room air filters are also a good idea.
• Get vaccinated!
• Wash your hands often.
• If you do get sick, STAY HOME! I have always hated the “brave” soul who came to work with a cough and sneeze. Don’t share your agony!!
• And there are the good old fashioned masks for use in crowded places, especially in auditoriums, on planes, and other packed indoor situations. I don’t care what the naysayers say about masks, they are flat wrong. They don’t think twice when a store sign requires shoes and shirts to enter. So why do masks bother them so much? They WORK as I have written here before, over and over. Empirical evidence proves masks work. That is why the entire medical profession continues to use them.

Finally, as I have repeatedly admonished, please get vaccinated. Vaccine and booster uptake for all three viruses has been dismal this year. Failure to vax is a major driver in the surge of the flu-like respiratory diseases we are seeing. If you have not gotten vaccinated for all three circulating viruses, why the heck not?? It is way better to prevent disease than to treat disease. A sore arm is much less of an inconvenience than suffering the flu, RSV or lying in a specialized hospital bed turned on your stomach breathing with a ventilator because of COVID.

As I have written in these pages, having COVID can be worse than any flu you ever had. It also puts adults at risk for dealing with weeks of long COVID and getting new-onset diabetes and immune dysfunction. COVID also is much worse than the flu for many kids and puts them at risk for multi-system inflammatory syndrome (MIS).

Why risk what can be prevented by a simple vaccination?

What We Learned From Sweden’s Response To COVID

“Sometimes I wonder whether the world is being run by smart people who are putting us on or by imbeciles who really mean it.”
― Laurence J. Peter, The Peter Principle

Many people have asked why we didn't let the virus hit us like a big wave and get it over with. The Great Barrington Declaration (GBD), a letter penned by three physicians, favored such an approach and called it “focused protection.” It recommended quarantining the highly vulnerable, i.e., the elderly and those with high risk factors like diabetes, heart and lung disease, etc., and letting the virus run amok through the rest of the population to quickly build natural herd immunity across the country. They said we should do away with non-pharmaceutical interventions that prevent infections, such as masks, sanitation, personal distancing, quarantines, closings, etc. The recommendation was published as a letter on October 5, 2020 because no medical journal would accept it as an article. Vaccines were still considered to be months away at that time, but actually began to roll out in mid-December of that year. Admittedly, the letter’s authors did not have a crystal ball.

We didn’t accept that recommendation, but Sweden did something very similar on their own and kept their country open and had considerably less morbidity and mortality than the US. Armchair health experts who learned their subjects at Google and Facebook Universities have been clucking their tongues and scolding the CDC and public health professionals ever since. Should we have responded like Sweden did? Would it have been better if we had followed the recommendations made in the GBD?

When the declaration came out, it was widely panned as being ridiculous by health experts and organizations around the world. A Yale epidemiologist pointed out that almost half the US population would be considered to have an underlying risk factor for COVID meaning that half the population would have to be quarantined from the other half, not much different from the protective measures already underway at that point. It also would have meant that people at less risk would be exposed to a rather nasty virus. They essentially would be sacrificed to a disease more lethal than any flu we have encountered since 1918. And then there is the problem with long COVID and other morbidities such as an uptick in new onset diabetes in many COVID survivors. Even though kids have a very low level of mortality from COVID, the disease was still much worse than any flu for them and too many of them were hospitalized in serious shape with a malady called multisystem inflammatory syndrome or MIS. This was the sacrifice the folks who proposed the GBD were willing to impose on half the population.

Anyway, this post is supposed to be about Sweden, not the US. Did Sweden’s experiment turn out as positive as many people believe? It depends on which countries you compare it to. Comparing the Swedish experience to that of the US, it seems they did pretty well. They did not shut down and had much less mortality than we did. But is that an accurate apples-to-apples comparison? Sweden is a country of just over 10 million people. Its demographic is much more homogenous than that in the US and it has much less poverty. In the US, COVID hit impoverished and minority populations especially hard. They have fewer medical resources to deal with the disease. In contrast, Sweden does not have such a large minority or poor population and it has cradle to grave social welfare for everyone, including medical care. It does not at all resemble the US.

It is more accurate to compare Sweden to its neighboring Nordic countries with similar populations, demographics, and social welfare, but that also enacted more stringent social controls in response to the pandemic like the US did.

It turns out that compared to other Nordic countries, Sweden fared quite poorly with the highest mortality rate. Sweden had four times the number of COVID deaths compared to many of its neighbors. In particular, it had ten times the COVID death rate of Norway.

What about the economy? Of course the Nordic countries that enforced public and commercial shutdowns suffered significant economic hits like the rest of the world. Importantly, so did Sweden, which kept its economy open. Nevertheless, the country suffered as much economic downturn as its neighboring countries that enforced stricter shutdowns. In fact, the Organization for Economic Cooperation and Development and Development (OECD), of which Sweden is a member, reported that the country actually did markedly worse than Denmark, Norway and Finland. It seems that economic health is not only related to open commerce, but also to the public health of the country. Sick people do not work or venture out to buy things. It seems that public health affects economic health. That was not considered in the GBD, which was concerned about the economic impact of closing down commerce via fiat. They did not consider the economic impact of closing down commerce by hospitalizing so many people.

As these effects of its open policies became clear, Sweden eventually began to enforce greater social restrictions later in the pandemic, but the damage had already been done. The architect behind its initial open policies eventually admitted that things did not work out as planned. And in December 2020, Sweden’s King Gustav publically declared that the government’s approach had failed.

The real lesson from Sweden is that if you keep things open and people get sick, the economy still suffers in a pandemic. As far as the economy goes, it is a case of “damned if you do and damned if you don’t” enforce public restrictions.

And if you don’t, people still get sick and die and dead people stop buying things.

US Life Expectancy Finally Bounces Back Up

“Game over, man! Game over!” --Bill Paxton as Private Hudson in Aliens

As I wrote in these pages a couple of years ago, the US suddenly lost a whopping 1.3 years of average life expectancy due to COVID. It had that big of an impact on the country in excess deaths. And before some moron starts saying it was due to vaccine deaths, the down turn in life expectancy, or the increase in excess deaths (i.e., deaths more than expected based on actuarial predictions) began before the vaccines rolled out and just after the virus appeared. Furthermore, the upturn in life expectancy occurred after the vaccines were delivered, as well as after the virus evolved from Delta to a less lethal variant. In the early days of COVID vaccination before vaccines were widely distributed, data showed that unvaccinated people were 11 times more likely to die from the virus than vaccinated people. At one point, 95% of hospitalizations and 99% of deaths were in unvaccinated people. The vaccines clearly prevent death, they do not cause death (unless you listen to Robert F. Kennedy, Jr. or Marjorie Taylor Greene, more on her later).

The graph below shows the dramatic drop in life expectancy beginning in 2019 and reversing about 2021. If vaccines were killing rather than saving people, you would think the curve would continue downward.
