The question 'can 5G cause Corona Virus or Covid-19' begs for answers that are based on facts and scientific proves overtime and not religious sentiments or for economic gains as believed by many in the world today. The most painful part is that fear has been induced in the world today via these unrealistic assertions that 5G can cause Coronavirus.

Lending my voice to scientists who have addressed this topic before now. Thanks to MrPhysics, a graduate of Nuclear Engineering  for his article "5G Network: Can It Cause Cancer or COVID-19". In his actual words:

Classifications of Radiations
They are two basic classification of radiations, they include:
1 Particle radiation: This contains charged and neutral particles

2. Electromagnetic radiation: (Photon flow. 5G belongs to this group.)
We can classify radiations according to their biological effects on matter, here, we have two types of radiations: Ionizing and non ionizing radiations.
You must have heard these two in recent times, so what is ionizing and non ionizing radiations?

a. Ionizing radiations: This means radiation have enough energy to eject one electron from the atom of the crossed material.

b. Non ionizing radiation: Particle energy is not enough to eject one electron from the atom, therefore it is said to have lower ionizing potential.

Having quoted MrPhysics. Here are my thoughts:

Covid 19 is a disease which is caused by a virus something completely different from to a mobile phone.

Viruses are tiny particles made up of genetic material, wrapped in a layer of proteins and fats.  They have no metabolism and can’t reproduce without causing an infection.  In the case of this coronavirus, it infects cells in human lungs in order to replicate, damaging them and also causing a harmful immune reaction in the process.  5G radio signals are electromagnetic waves, very similar to those already used by mobile phones (2G, 3G and 4G).  Electromagnetic waves are one thing, viruses are another, and you can’t get a virus on a Base Station (Mast).

There is no sensible link between the use of 5G frequencies and COVID-19 or any other virus or bacteria.  This sort of conjecture only contributes to the risk to individuals who are prepared to believe such non-science as opposed to the considerable efforts being made by medical science to enable the population to protect themselves in an informed manner.

The energy of the 5G wave is insufficient to break bonds and hence it is called ‘non-ionising’ as opposed to ‘ionising’ radiation such as X-rays.

Furthermore, the intensity transmitted from the masts is extremely low.  The risk from jeopardising a means of communication at the current time is of concern and is entirely unwarranted.

The supposed correlation between 5G and its development in China reveals a complete lack of understanding of the difference between cause and coincidence.  In the simplest terms there might have been a train leaving Wuhan station during 5G development, but the train departure was not caused by 5G.

The idea that COVID19 is caused by 5G mobile phone signals is complete rubbish. This is a disease which numerous doctors and scientists around the world have said is caused by a virus, something completely different to a mobile phone signal.

“The present epidemic is caused by a virus that is passed from one infected person to another. We know this is true. We even have the virus growing in our lab, obtained from a person with the illness. Viruses and electromagnetic waves that make mobile phones and internet connections work are different things. As different as chalk and cheese. The internet connections these networks give us are one of the most important tools we are using to coordinate our response to the epidemic and efforts to do research to overcome it. Damaging phone masts is like knocking holes in your lifeboats while your ship sinks." (Prof Adam Finn, Professor of Paediatrics, University of Bristol)

I am a graduate of Electrical Engineering who studied Electomagnetism and Electromagnetic Field theories at different levels. There is no scientifically credible evidence to link the introduction of 5G masts with the COVID-19 outbreak. This would be both a physical and biological impossibility.

Also your immune system can be dipped by all sorts of thing - by being tired one day, or not having a good diet. Those fluctuations aren't huge but can make you more susceptible to catching viruses.
While very strong radio waves can cause heating, 5G is nowhere near strong enough to heat people up enough to have any meaningful effect.

Radio waves can disrupt your physiology as they heat you up, meaning your immune system can't function. But [the energy levels from] 5G radio waves are tiny and they are nowhere near strong enough to affect the immune system. There have been lots of studies on this.

The radio waves involved in 5G and other mobile phone technology sit on the low frequency end of the electromagnetic spectrum. Less powerful than visible light, they are not strong enough to damage cells thereby making it impossible to transmit virus.

It's also important to note another major flaw with the conspiracy theories - Coronavirus is spreading in Nigeria cities such as Lagos, Abuja, Benin, etc and  UK cities where 5G has yet to be deployed, so, what is causing and spreading the virus over there? 5G network I guess!

On a final note, Viruses invades human or animal cells and use them to reproduce, which is what causes infection. Viruses cannot live very long outside a living thing, so they have to find a way in - usually via droplets of liquid from coughs or sneezes.
Genome sequencing of this coronavirus suggests it jumped from animals to humans - and then began to pass from human to human. This is not a characteristics of an Electromagnetic radiation, in this case 5G radio waves.

Conclusively, while we wait for other evidence as to what causes this virus and how it can be eliminated, 5G cannot be related to COVID 19 and cannot transmit the virus.

Just wait for those whose daddy in faith has said otherwise.

Even South Korea dey use up to 7g sef and they have one of the least case of Covid 19
