There is no virus..the real/true virus are the SATANIC con artists in the idiot box, i mean in the teLIEvision, aka the satanic media... they are the only and true viruses
5g, 6g, 7g are frequency/electromagnetic weapons that poison the cells, as a response, the cells make soaps/solvents('viruses') to try to detox these poisons, lets not even talk about the poisons in the food, air, water, clothes, carpets, furniture, cleaning products, cosmetics, paints, artificial light , GMOS, nano technology, METABOLIC WASTE PRODUCTS, pharmaceuticals etc.etc....
THESE are the REAL/TRUE causes of 'diseases' and off course, nutrient deficiencies(amino acids, fatty acids, minerals, vitamins, water) also cause ''diseases...
when you have no nutrient deficiencies, your body would be able to get rid of all of these poisons and maintain homeostasis(health) .. it is fairly simple and known for 6000 years.
The word 'contagious' is meaningless, The word ''immune system'', again, meaningless.
The ''immune system'' is the body's stock of amino acids, fatty acids, minerals, vitamins, water.
You cannot ''catch'' a ''disease'' or ''virus''... you can only become contaminated with man made chemicals, FLOATING AROUND IN THE AIR, mixed in food, water etc...
When nutrient levels become too low, the body will create bacteria and or viruses and or worms to help with detoxification of these harmful man made agents/chemicals.
If you study ancient medicine, you will never find contagious anything, they all knew that ''diseases'' are caused by lifestyle choices and environment the individual lives in, especially digestion and elimination, aka what can you digest/absorb and what can you eliminate.
