It turns out that 5G is more dangerous than 4G. They need a tower every few meters for 5G, and they put out radiation in the millimeter range. For brief exposure, millimeter radiation is not too bad. But, if you are in it all the time, it is quite dangerous and eventually will lead to health issues. This is true with regular microwaves, but you need more dosage for longer periods to do any significant damage. Even radio waves can mess with your health in large enough doses in time.
However, 5G cannot cause coronavirus, or any other virus or bacteria. It can't even cause a regular virus (such as a regular cold) to mutate (you would need much more energy that is more likely to kill the virus). It can make one more susceptible to these viruses in high enough doses, as with any other stress. Beyond this, I think more people are going to die from the panic and spot shortages that the virus scare will create than from the disease. And even more from the communism that this is going to generate--mandatory shots that contain an even worse agent or chemical poisons, mandatory sharing of all provisions (which is communism), and so on. You can prepare for the virus--quit smoking if you still smoke, and get your supplements. You can prepare for the shortages--stock up on medium and long shelf life groceries before they disappear. But, for the communism, no preparation will do more than get you thrown in the gulags.
