Hospitalizations Are The Only Accurate Gauge
Hospitalizations historically appear to be little affected by weekends or holidays. The hospitalization growth rate trend continues to improve.
source: https://gis.cdc.gov/grasp/covidnet/COVID19_3.html
Historically, hospitalization growth follows new case growth by one to two weeks.
As an analyst, I use the rate of growth to determine the trend. But, the size of the pandemic is growing in terms of real numbers – and if the rate of growth does not become negative – the pandemic will overwhelm all resources.
The graph below shows the rate of growth relative to the growth a week earlier updated through today [note that negative numbers mean the rolling averages are LOWER than the rolling averages one week ago]. As one can see, the rate of growth for new cases peaked in early December 2020 for Thanksgiving, and early January 2021 for end-of-year holidays – and it now shows that the coronavirus effect is improving.
In the scheme of things, new cases decline first, followed by hospitalizations, and then deaths. The potential fourth wave did not materialize likely due to immunizations.
Coronavirus and Recovery News You May Have Missed
We Were Told Our Lives Would Get Back To Normal With The Vaccines. Now The Reality Is They Do Not Work As Well As Advertised – Econintersect
[1] Today’s vaccines provide only a fraction of the true level of protection required. Their actions are in many ways similar to applying weed killer at half the strength needed to kill the weeds or providing antibiotics at half the dose required to stop the spread of bacteria. [2] In a way, getting sick from a virus is helpful. It tells us to stay at home, away from others. It is the fact that humans experience symptoms from viruses that tends to limit their spread. [3] It is becoming clear that people immunized with today’s vaccines can both catch the delta variant and spread it to others. [4] With nearly all of the current vaccines, the immune system is trained to look for the spike protein from the original Wuhan virus. This narrow focus makes it relatively easy for the virus to mutate in ways that outsmart the vaccine. [5] Given the likelihood of mutations away from the narrow target, it seems strange that the governments have set very high expectations for the new vaccines. [6] Leaky vaccines, if widely used, can encourage the virus to mutate toward more virulent (severe) forms. Ultimately, the problem becomes viruses that mutate to more virulent forms faster than the vaccine system can keep up. [7] Another potential problem with COVID-19 vaccines is Antibody Dependent Enhancement (ADE). When this occurs, it worsens later infections by different variants. [8] Another problem with the current vaccines against COVID-19 is that immunity may not last very long. [9] The public has been led to believe that vaccines are the only solution to COVID-19 when, in fact, they are at best a very poor and temporary band-aid. [10] The pharmaceutical industry has been telling the world that inexpensive drugs can’t fix our problem. However, there are several low-cost drugs that appear helpful. [11] Conclusion. Governments, businesses, and citizens need to understand that today’s vaccines are not really solutions to our COVID-19 problem. At the same time, they need better solutions.

Recovered COVID Patients Suffering ‘Significant Cognitive Deficits’ According To Large-Scale UK Study – ZeroHedge
Over 190 million people have officially contracted SARS-CoV-2, the virus which causes Covid-19. Of that, the vast majority have recovered – while up to one-third reportedly suffer from lingering symptoms of varying severity, known as ‘long covid.’
Common complaints include a lack of smell and taste, as well as “brain fog” – in which sufferers often complain of ongoing confusion, lack of focus, and migraines – well after they’ve ‘recovered’ from the disease.
Last week, The Independent reported that Covid-19 may accelerate the onset of Alzheimer’s disease in patients suffering from neurological symptoms, while another study noted in the report found that coronavirus patients “are more susceptible to long-term memory and thinking problems.”
Last September, a study offered the first clear evidence that Covid-19 ‘hijacks’ brain cells to make copies of itself – starving nearby cells of oxygen. The same researchers found last July that some Covid-19 patients have developed serious neurological complications, including nerve damage.
Now, a large-scale study in the UK of more than 80,000 participants “offers convincing evidence that COVID-19 may indeed result in long-term cognitive deficits – even in those who suffer the mildest form of the disease,” according to Dr. Rhonda Patrick.
COVID Vax Doubled Protection for the Previously Infected – MedPage
Unvaccinated adults who were previously infected with COVID-19 were twice as likely to be reinfected as those previously infected but also fully vaccinated, researchers found.
A case-control study in Kentucky found a more than two times higher risk of COVID-19 cases among unvaccinated adults with prior infection compared with their fully vaccinated counterparts (OR 2.34, 95% CI 1.58-3.47), reported Alyson Cavanaugh, PhD, of the CDC, and colleagues, writing in an early edition of the Morbidity and Mortality Weekly Report.
Notably, the data were from May to June 2021, prior to reports of the Delta variant becoming the predominant strain in the U.S.
“This study shows you are twice as likely to get infected again if you are unvaccinated,” CDC Director Rochelle Walensky, MD, said in a statement. “Getting the vaccine is the best way to protect yourself and others around you, especially as the more contagious Delta variant spreads around the country.”
Cavanaugh’s group added that not only does the study suggest that being unvaccinated is associated with a higher likelihood of being reinfected, but “full vaccination is associated with reduced likelihood of reinfection” among those previously infected.
Potential military vaccine mandate brings distrust, support – AP
Since President Joe Biden asked the Pentagon last week to look at adding the COVID-19 vaccine to the military’s mandatory shots, former Army lawyer Greg T. Rinckey has fielded a deluge of calls.
His firm, Tully Rinckey, has heard from hundreds of soldiers, Marines and sailors wanting to know their rights and whether they could take any legal action if ordered to get inoculated for the coronavirus.
“A lot of U.S. troops have reached out to us saying, ‘I don’t want a vaccine that’s untested, I’m not sure it’s safe, and I don’t trust the government’s vaccine. What are my rights?'” Rinckey said.
Generally, their rights are limited since vaccines are widely seen as essential for the military to carry out its missions, given that service members often eat, sleep and work in close quarters.
Defense Secretary Lloyd Austin has said he is working expeditiously to make the COVID-19 vaccine mandatory for military personnel and is expected to ask Biden to waive a federal law that requires individuals be given a choice if the vaccine is not fully licensed. Biden has also directed that all federal workers be vaccinated or face frequent testing and travel restrictions.
Lawyers say the waiver will put the military on firmer legal ground so it can avoid the court battles it faced when it mandated the anthrax vaccine for troops in the 1990s when it was not fully approved by the federal Food and Drug administration.
The distrust among some service members is not only a reflection of the broader public’s feelings about the COVID-19 vaccines, which were quickly authorized for emergency use, but stems in part from the anthrax program’s troubles.
Scores of troops refused to take that vaccine. Some left the service. Others were disciplined. Some were court martialed and kicked out of the military with other-than-honorable discharges.

‘Breakthroughs’ in Highly Vaxxed Bay Area Spur Interest in Boosters – MedPage
As breakthrough COVID infections among staff at Bay Area hospitals garner attention as the latest Cape Cod-like cluster, one of these facilities has started offering booster shots for some.
Zuckerberg San Francisco General Hospital (ZSFG), a public hospital that is part of the San Francisco Department of Public Health, said it will accommodate special requests for a supplemental dose of COVID-19 vaccine — using either Pfizer or Moderna’s mRNA shot — from people who have previously received the Johnson & Johnson viral vector vaccine.
However, the Department of Public Health has been emphatic in stating that the move doesn’t represent a change in policy, and that in many cases of such requests, individuals have consulted with their doctor about receiving the supplemental dose.
The department said it continues to align with CDC guidance and is not currently recommending booster shots. “We will continue to review any new data and adjust our guidance, if necessary,” they noted. ZSFG declined to make a member of its leadership team available for an interview on the availability of supplemental vaccine doses.
Out of 7,000 staff members at ZSFG, 55 are currently COVID-positive, the hospital said in a statement. To its knowledge, none of the infected employees have been hospitalized.
“Breakthrough cases were and still are expected,” they said. “We know vaccines won’t completely prevent infections, but they are very effective at making hospitalizations and death preventable.”
Climate crisis: Scientists spot warning signs of Gulf Stream collapse – Guardian
Climate scientists have detected warning signs of the collapse of the Gulf Stream, one of the planet’s main potential tipping points.
The research found “an almost complete loss of stability over the last century” of the currents that researchers call the Atlantic meridional overturning circulation (AMOC). The currents are already at their slowest point in at least 1,600 years, but the new analysis shows they may be nearing a shutdown.
Such an event would have catastrophic consequences around the world, severely disrupting the rains that billions of people depend on for food in India, South America and West Africa; increasing storms and lowering temperatures in Europe; and pushing up the sea level off eastern North America. It would also further endanger the Amazon rainforest and Antarctic ice sheets.
Moderna recommends third shot of vaccine to defend against new coronavirus strains – Yahoo
Moderna said Thursday that people will likely need a COVID-19 vaccine booster dose to protect against future mutations of the coronavirus, touting the “robust” antibody response generated by the additional shot.
Vaccine developers at Moderna “are looking forward towards our vision of a single dose annual booster that provides protection against COVID-19, flu and [respiratory syncytial virus] for adults. … We believe this is just the beginning,” CEO Stephane Bancel said.
The company has conducted studies to determine the benefits of administering a third “booster” shot of its two-dose vaccine to protect against the highly contagious delta variant that accounts for a majority of COVID-19 cases, as well as any future strains of the virus that develop.
Moderna’s Phase 2 trial of a 50-microgram booster dose generated a strong immune response against the delta, gamma, and beta variants — all of which seem to spread more easily and quickly than other variants, which could lead to more COVID-19 outbreaks. The third dose produced an antibody response nearly as strong as the response generated in previously unvaccinated people who received the first two doses of the vaccine.
The company also reported that its two-dose vaccine created lasting immunity months after receiving the second shot. The vaccine was still 93% effective after six months, compared to an efficacy rate of about 94% two weeks after received the second shot.
Pfizer has manufactured the first batch of Delta variant vaccines – FreeThink
Pharma giant Pfizer has already developed and manufactured ingredients for a COVID-19 vaccine targeting the highly contagious Delta variant.
The Delta variant: As the coronavirus spreads, its genetic code can undergo mutations. Versions of the virus with a unique set of mutations are called a new variant or strain.
New strains are common and usually fizzle out on their own.
But the coronavirus’s Delta variant, however, has taken off across the world since its discovery — it’s now behind more than 90% of new coronavirus cases in the U.S.
The challenge: Data suggests that the Delta variant is possibly twice as transmissible as the original strain, and there’s some early evidence that it might lead to more severe cases.
Even for vaccinated people, now is the time for masks and testing, public health experts say – NBC
As the highly transmissible delta variant sweeps across every state in the country as the dominant strain of Covid-19, public health experts warn now is not the time to ditch masks or forgo testing.
If anything, the United States, particularly in areas where vaccination rates have stalled and coronavirus cases are rising, is at an urgent juncture in the pandemic, in which continued mask-wearing and testing are pivotal because of how quickly the variant has been spreading, the experts say.
“I think it’s critical to be masking indoors no matter where you live,” Susan Hassig, an epidemiologist at the Tulane University School of Public Health and Tropical Medicine, said Wednesday as her home state of Louisiana was poised to exceed the peak of hospitalized Covid patients since the pandemic began.
Lambda COVID Variant ‘a Potential Threat to Human Society,’ Researchers Say – Newsweek
There is concern over the threat posed by the Lambda variant of COVID-19 which may be more resistant to vaccines than the original version of the virus.
Research by a team from the University of Tokyo, which has not yet been peer-reviewed, found that three mutations in Lambda’s spike protein help it resist neutralization by vaccine-induced antibodies.
Meanwhile, two mutations in the Lambda variant—T76I and L452Q—make it more infectious than the COVID variant that swept through the world in 2020.
The conclusions of the study posted on BiorXiv on July 28 matched findings—also not yet peer-reviewed—by a team in Chile that found the variant might also evade vaccine antibodies, Infection Control reported.
FDA Reportedly Planning For COVID Vaccine Booster Shot Approval By September – ZeroHedge
Confirming what we have all suspected (and The White House, France, and Germany all confirmed), The FDA has tonight confirmed, according to people familiar with discussions within the agency, expects to have a strategy on Covid-19 vaccine boosters by early September that would lay out when and which vaccinated individuals should get the follow-up shots.
The Wall Street Journal reports that the Biden administration is pushing for the swift release of a booster strategy because some populations – people age 65 or older and people who are immunocompromised, as well as those who got the shots in December or January shortly after they were rolled out – could need boosters as soon as this month, two of the people said.
So we have gone from double-masking to triple-jabbing… one wonders when it will end?
Will the obese, old, or immunocompromised be expected to take bi-annual booster shots for the rest of their lives… and what do they think this will do to the masses of unvaccinated people?
And what happens when the ‘Delta’ variant runs it’s course?
Perhaps it’s time to switch from ‘Greek’ identifiers for variants to Cambodian (the Khmer alphabet has 74 letters).

Intel agencies scour reams of genetic data from Wuhan lab in Covid origins hunt – CNN
US intelligence agencies are digging through a treasure trove of genetic data that could be key to uncovering the origins of the coronavirus — as soon as they can decipher it.
This giant catalog of information contains genetic blueprints drawn from virus samples studied at the lab in Wuhan, China which some officials believe may have been the source of the Covid-19 outbreak, multiple people familiar with the matter tell CNN.
It’s unclear exactly how or when US intelligence agencies gained access to the information, but the machines involved in creating and processing this kind of genetic data from viruses are typically connected to external cloud-based servers — leaving open the possibility they were hacked, sources said.
Still, translating this mountain of raw data into usable information — which is only one part of the intelligence community’s 90-day push to uncover the pandemic’s origins — presents a range of challenges, including harnessing enough computing power to process it all. To do that, intelligence agencies are relying on supercomputers at the Department of Energy’s National Labs, a collection of 17 elite government research institutions.
Pfizer/BioNTech COVID-19 vaccine offers decreased protection six months after second dose, suggests Israeli study – News-Medical
… The median time between when the participants had received the second dose of the COVID-19 vaccine and received an RT-PCR test was 146 days. However, over 50% of the participants had received an RT-PCR test over 146 days since their second dose.
Using 146 days as their cut-off, the researchers found that within the 60 and over age group, 2.19% of vaccinated individuals tested positive for SARS-CoV-2. Comparably, the positivity rate in the 40-59 and 18-39 age groups was 1.93% and 1.39%, respectively. Taken together, the increase in SARS-CoV-2 infection rates across all patient populations was significant.
Notably, at the time when the study was conducted, the dominant circulating variant was the SARS-CoV-2 Delta variant B.1.617.2. Of the 113 isolates that were sent for sequencing in this study, 93% tested positive for the Delta variant.
Conclusion
While the incidence of breakthrough SARS-CoV-2 infections was significant across all age groups, the strongest increase was observed for patients aged 60 and older. These results therefore support the concept that the immune response to vaccines is influenced by age-related changes of the immune system.
Since Israel was one of the first nations to initiate a large-scale national vaccination campaign, most of the participants in this study received their second dose of the BNT162b2 vaccine at least six months before the study was conducted. The results described here therefore demonstrate the diminishing protection offered by COVID-19 vaccines over time from when the individual received their second dose. This study also provides information on the protection offered by the BNT162b2 vaccine against the SARS-CoV-2 Delta strain that is now dominant worldwide.

15 states are keeping COVID breakthrough cases under wraps – The Hill
State health departments across the country are taking various approaches to how they keep records on COVID-19 breakthrough cases, with 15 states deciding not to publish any data on the rare incidents.
An analysis by The Hill found that 35 states have disclosed some data on fully vaccinated people who later contracted COVID-19. The information ranged from a one-time percentage of residents who experienced a breakthrough infection to weekly detailed overviews broken down by demographics such as age, sex and race.
Figures on breakthrough cases are not available on the health department websites, social media or other publicly accessible sites for the other 15 states: Florida, Iowa, Kansas, Kentucky, Minnesota, Missouri, Nevada, New Hampshire, New York, North Dakota, Ohio, Pennsylvania, South Dakota, Texas and Wisconsin.
The Hill reached out to the health departments of all 15 states for comment. A handful of states, including New York, Texas and Wisconsin, provided the numbers upon request.
Alicia Shoults, a spokesperson for the Ohio Department of Health, told The Hill that the agency plans to publish a dashboard with breakthrough hospitalizations and deaths Friday.
Of the states already reporting data, Utah topped the list, with 0.36 percent or 5,265 breakthrough cases in its 1,462,313 fully vaccinated residents from Jan. 16 until this week. In that period, the state reported approximately 115,000 coronavirus cases.
The Centers for Disease Control and Prevention (CDC) stopped monitoring nonsevere breakthrough cases in May.

Warning to Readers
The amount of politically biased articles on the internet continues. And studies and opinions of the experts continue to contradict other studies and expert opinions. Honestly, it is difficult to believe anything anymore.

I assemble this update daily – sifting through the posts on the internet. I try to avoid politically slanted posts. This daily blog is not an echo chamber for any party line – and will publish controversial topics unless there are clear reasons why the topic is false. And I usually publish conflicting topics. It is my job to provide information so that you have the facts necessary – and then it is up to readers to draw conclusions. It is not my job to sell any point of view.
Analyst Opinion of Coronavirus Data
There are several takeaways that need to be understood when viewing coronavirus statistical data:
- The global counts are suspect for a variety of reasons including political. Even the U.S. count has issues as it is possible that as much as half the population has had coronavirus and was asymptomatic. It would be a far better metric using a random sampling of the population weekly. In short, we do not understand the size of the error in the tracking numbers.
- Just because some of the methodology used in aggregating the data in the U.S. is flawed – as long as the flaw is uniformly applied – you establish a baseline. This is why it is dangerous to compare two countries as they likely use different methodologies to determine who has (and who died) from coronavirus.
- Older population countries will have a significantly higher death rate as there is relatively few hospitalizations and deaths in younger age groups..
What we do or do not know about the coronavirus [actually there is little scientifically proven information]. Most of our knowledge is anecdotal, from studies with limited subjects, or from studies without peer review.
- How many people have been infected as many do not show symptoms?
- Masks do work. Unfortunately, early in the pandemic, many health experts — in the U.S. and around the world — decided that the public could not be trusted to hear the truth about masks. Instead, the experts spread a misleading message, discouraging the use of masks.
- Current thinking is that we develop at least 12 months of immunity from further COVID infection.
- The Moderna and Pfizer vaccines have an effectiveness rate of about 95 percent after two doses. That is on par with the vaccines for chickenpox and measles. The 95 percent number understates the effectiveness as it counts anyone who came down with a mild case of Covid-19 as a failure.
- To what degree do people who never develop symptoms contribute to transmission? Research early in the pandemic suggested that the rate of asymptomatic infections could be as high as 81%. But a meta-analysis, which included 13 studies involving 21,708 people, calculated the rate of asymptomatic presentation to be 17%.
- The accuracy of rapid testing is questioned – and the more accurate test results are not being given in a timely manner.
- Can children widely spread coronavirus? [current thinking remains that they are a minor source of the pandemic spread]
- Why have some places avoided big coronavirus outbreaks – and others hit hard?
- Air conditioning contributes to the pandemic spread.
- It appears that there is increased risk of infection and mortality for those living in larger occupancy households.
