Talk of a connection between 5G and COVID-19 has been met with denouncements and ridicule in the media. As far as they are concerned, it's not possible. There is no evidence to even consider this possible. Well, the media is wrong.

This started out with a viral audio/video of someone claiming to be a former exec of a British telecom giant. He claimed that there was no virus, and that all the deaths are because of 5G. David Icke then espoused a similar narrative shortly after. Talking about the link between 5G and COVID-19 is what ultimately got him banned from YouTube, and then from Facebook.
In fact, this allegation of 5G and COVID-19 deaths is what started the initial YouTube censorship around COVID-19. Then it progressed to encapsulate anything that wasn't supported by the WHO. That is, anything that contradicted the position of the WHO about COVID-19 was in breach of YouTube's new rules and would be banned/censored from the platform.
Why did they freak out so much about these claims? One thing is that people were starting to attack and destroy the 5G towers. I suspect they have ties with the telecom giants who are rolling this out and don't want the rollout disrupted or for the damage to cost the telecom industry money.
It's odd that the 5G rollout was considered "essential work" while other businesses were shutdown during the draconian tyrannical government lockdown. Very suspect. Since hadly any devices use 5G. It's clearly not essential even for communication. But it is essential to hurry and bring in an IoT future of everything connected into a big data world, with smart cities and surveillance tracking.
Study correlating 5G and COVID-19
A study was published in Spain last month by Bartomeu Payeras i Cifre. He set out to see if there was any correlation between cases of COVID-19 and 5G, since there was such fervor to denounce these claims as untrue. It turns out there is a correlation between 5G setups and operation, and the emergence of COVID-19 cases. There is a translation of the study here and here.
The study compared many different areas with and without 5G:
The method used was to compare the incidence (no. of cases per 1000 inhabitants) between countries with and without 5G technology. Between regions of the same country with and without 5G technology. Between cities of the same state with and without 5G technology. Between different neighbourhoods of the same city with the 5G network map of that city. Comparing states with common borders with and without 5G technology.
Portugal, Spain, Italy and Greece
One of the first comparisons was 4 countries at roughly the same latitude: Portugal, Spain, Italy and Greece. Spain and Italy are the two which have 5G.
The average infections of 5G Spain and Italy were 220% more than non-5G Portugal and Greece.
San Marino, first European state to get 5G
This is interesting. It was the first state to get 5G in Europe. It also had the highest number of cases per 1000 people. Looking at Italy overall, which surrounds San Marino, San Marino has 4.07 times more cases than Italy, and 27 times more cases than Croatia which does not have 5G.
New York
This correlation is visually evident as well. You can see the dark red cases of COVID-19 correlate well with the darker spots of 5G coverage:
South Africa
South Africa is the only place with 5G in Africa, and it has the highest number of cases.
Probability of random phenomenon
Here is a summary of the probability findings. You can go look more closely at the links above if you want to see the calculations.
The probability calculation is obtained by dividing the number of favourable cases by the number of possible cases. If the result shows that it is not a random phenomenon, it shows sufficient causal reason to analyze the causes.
(a) Probability that the 9 most contagious countries on the planet are countries with 5G networks.
The probability is 1 in 680,000,000.
If we include Japan, which also has 5G and rates of infection similar to those of South Korea …the probability is 1 in 8,500,000,000.
(b) Probability that the 5 most contagious countries in Europe have 5G networks.
The probability is 1 in 637.
The case of San Marino is highly significant.
It is located within the Italian territory, with a similar culture, economy, and social level, but presents much higher rates of infection. The only difference is the time of exposure of its citizens to 5G radiation, because it was the first state in the world to implement such technology on 4 September 2018, while in Italy it was 5 June 2019. This opens the door to debate about the likely influence of 5G on the increase in the rates of infection.
The probability is 1 in 37,636.
Conclusion
The analysis concludes that the is a " clear and close relationship between the rate of coronavirus infections and 5G antenna location."
It notes that it doesn't analyze any benefit or harm to human health from 5G electromagnetic radiation, but it does indicate a possible cause-effect from the COVID-19 pandemic.
These data and results have the value of being taken “in vivo”, not based on prospective or laboratory studies. Never before have we had so much epidemiological information about a disease in humans to be able to produce scientific studies. A means of answering the question of cause and effect would be to disconnect the 5G networks, at least as a preventive measure, and see the results of the evolution of cases of coronavirus. So would studying the rate of infection in a state that declared a 5G moratorium after the pandemic started and studying if the statistics change.
Given the evidence presented here, the data and conclusions of this study urgently need to be given due consideration. Given the current gravity of the pandemic, the media and political and health authorities have a responsibility to take urgent action. A failure to act in the face of the findings of this study could be considered negligent at the very least and very possibly criminal.
It could be that there is a virus causing illness in a small percentage of the population who becomes infected, and that the number of infected or severity of symptoms could be exacerbated by the presence of 5G frequencies.
As the study suggests, disabling 5G networks would be prudent. Especially if there is a "second wave" as have been predicted. I doubt this will happen. But it would show if 5G is indeed increasing the number of cases or severity of the illness.
There isn't proof that 5G kills, or 5G causes the illness, or 5G makes people sicker from COVID-19. Contrary to the media denouncing any relation whatsoever, there is a correlation between 5G and COVID-19 cases, and potentially severity as well when I look at NYC.
