Across many parts of the world “the flu” disappeared in 2020, not to return until late 2021, the question is why?

“The flu” includes all respiratory viruses that cause flu-like symptoms, not just influenza, yet influenza has been the target virus, said to be “associated” with the burden of deaths. Not just influenza, but all influenza-like illness (ILI) disappeared shortly after the pandemic was declared March 11, 2020. What caused the dramatic exit? Was there in fact no incidence of ILI or were and flu-like cases redirected to COVID-19? Was it the “power of the pen” coupled with a not-fit-for-purpose “diagnostic” test that make everyone statistically ill with COVID-19? And what would be the purpose of that!!!?

Did PCR testing “diagnose” COVID-19 in place of other flu’s?

A Recap:

On January 13, 2020 the World Health Organisation (WHO) publishes the protocol for RT-PCR assay designed by a WHO partner laboratory to diagnose infection of the novel coronavirus. Then on January 30, 2020 they declare a Public Health Emergency of International Concern (PHEIC), which sets in motion the production of PCR test kits for the “novel coronavirus” under emergency use legislation. By the next week the “super spreader” narrative was born, a phenomenon where healthy people, showing no symptoms (asymptomatic), were allegedly spreading the virus.

COVID-19 was declared by the WHO as a “pandemic” on March 11, 2020 after which PCR testing for “COVID-19” was ramping up all over the world (note they never called it SARS-CoV-2 testing!). As an example, on that very same day in my state of South Australia, the first drive-through testing clinic opened south of Adelaide, of which anyone could get PCR tested for “COVID-19”, no matter if they had flu symptoms or not.

Public Health and the media had promoted the super-spreader narrative hard, images of people dying were constantly reported and the people had become super fearful of catching the “deadly” virus, especially from their healthy neighbour! On March 16, 2020 the WHO Director-General declared all countries mush “test, test, test” on the premise that in doing so is “the only way to really understand how much the coronavirus is spreading” – because too many DIDN’T become seriously ill!

Greater than 33 cycles not viable virus

On March 31, 2020 French doctor and researcher Dr Didier Raoult and colleagues, published a paper on a pre-print server where their data showed that any “positive” RT-PCR test cycled greater than 33-34 cycles does not have viable virus, meaning the person is not contagious. Tests cycled greater than 33 would return a false positive 80% of the time, meaning any genetic material detected was NOT viable virus, meaning the virus can not replicate, for all intents it is “dead”. Infecting another person was not probable.

PCR testing labs use 40-45 cycles

By mid-March 2020 everything was in place for escalating the COVID-19 “case” statistics. A case being anyone with a positive (or false positive) PCR result – with or without symptoms of illness. The PCR test kit production was in full swing, public health and the media had instilled the fear, the countries had established their drive-through testing sites and the testing labs were instructed to cranked up the PCR cycles to an unprecedented threshold of 40-45 cycles – a sure way to return a “positive” result.

To understand this, the labs doing the PCR testing could keep churning the machines over and over and over right up to a set cut-off point, in the case of COVID-19 tests this was set high, at 40 or 45 cycles, depending on the country – instead of stopping at 33 cycles. The machine would stop when a fluorescence was indicated. If the machine was set to keep going through 40 cycles a fluorescence was likely to occur, and as such a “positive” result was likely. A meaningless result clinically, but great for the “COVID-19 case” toll.

But add to this, the testing labs did not report the cycle threshold (Ct) for ANY test. Reporting the Ct value for any PCR test, under normal circumstances is necessary for a doctor to confirm a diagnosis, if the Ct was really high then the diagnosis may be incorrect. PCR tests have a history of causing fake or “pseudo-epidemics“.

If someone had flu-like symptoms from mid-2020 and a COVID-19 PCR test was undertaken, there was a strong chance of a positive result and so their ILI would be diagnosed as COVID-19 where true or not. That person could have had any number of the respiratory illnesses, but because the PCR tests were dialled up so high, they became a COVID-19 case.

Dr Tyson state [@47min] back in August 2021, that on death certificates of those who died of/with COVID-19 around early March/April 2020, many also had Influenza A or B listed too, meaning they had multiple infections. Once the influenza tests kits ran out, I guess they could no longer determine the existence of other pathogens.

What could explain where the flu went?

So where exactly did flu go in 2020? Was it PCR testing, the excellent selective filtering of cloth masks (SARS-CoV-2 still got through!), or was it because of lockdowns!? Was it the mass flu-vaccine campaign in early 2020 that worked on all viruses? Did COVID-19 out-compete ALL other respiratory viruses? Was it all of the above, more, or was it simply just re-categorised and never disappeared?

This page will capture information pertaining to respiratory viruses categorised as flu, influenza and influenza-like illness in relation to helping discover what happened to “the flu” in 2020-21, and why it returned in late 2021. I will include some historical data for more context.

Any non-influenza flu disappeared in the 1918 pandemic too!

Did you know that during the 1918 pandemic, as reported in US vital statistics, all respiratory viruses besides influenza, disappeared! Death certificates were influenza or pneumonia. [see 1918 below]


Two popular competing explanations for why ‘flu’ vanished from the globe in 2020/21 only to return 2021/22 and in some counties not until 2022/23 – according to PANDA:

  1. The first is that viral interference between SARS-CoV-2 and flu, where flu was outcompeted by SARS-CoV-2, lead to a collapse in flu rates. i.e. competition
  2. The second is that human interference caused reported flu rates to drop. Changes in flu testing, testing protocols and sequencing, and the partial demolition of national flu surveillance systems, may each have contributed to a reduction in reported flu rates, meaning that a form of observation bias may have hidden flu.” i.e. power of the pen and accessibility to testing

Lack of “flu” broke CDC’s computer model!

The 2020-2021 computer model estimates for Influenza Burden and how much Influenza was “prevented” by vaccination are not available due to minimal influenza activity” according to the CDC. I wonder how much respiratory virus testing was actually done over the entire period? I can’t find that data.

But the fact that they have to detect influenza in order to determine if the vaccine works is strange. This means someone has to have positive test for influenza when the are vaccinated, to determine the vaccine is “preventative” for symptomatic illness and averting medical visits. That doesn’t make sense to me.

1918-1919

As reported by the CDC’s own mortality statistics, all other respiratory viruses effectively disappeared during the 1918-19 pandemic. Everything was categorised as either influenza or pneumonia.

  • CDC Official mortality statistics – ALL, 1918 – PDF, ARCHIVE, 1919 – PDF, ARCHIVE

In studying the effects of the pandemic of influenza is is not believed to be best to study separately influenza and the various forms of pneumonia, bronchitis, and the respiratory diseases, for doubtless many cases were returned as influenza when the deaths were caused by pneumonia, and vice versa.

The best method therefore seems to be to study as one group deaths from influenza and pneumonia (all forms), disregarding deaths from the other respiratory diseases, which were comparatively few. In fact it is very remarkable how little difference it makes whether the pandemic mortality is measured by the excess mortality from influenza and pneumonia (all forms) or by the excess mortality from influenza and diseases of the respiratory system.

As stated in CDC mortality statistics report 1918 & 1919
