Are you meaning how is a cold transmitted to others? People in the same environment will be getting toxins say from 5g. It is electromagnetic radiation. It can kill. The body will be trying to detox from whatever toxins have got into the body..and if someone else close to them gets a "cold" it means they are detoxing too.

Read the link. In fact read the longer post where she covers 5g radiation poisoning.

. Schools have a lot of 5g equipment. In Hong Kong they understand it's 5g ..the young are bringing down the towers..I saw video about it. ..fluoride in the water.. it's a deadly neurotoxin...causes cancer quicker than anything else. Is it in your toothpaste? Do you cook with it? is your son eating school meals.
