The last article I put up was about face masks and facial protection and I highly suggest reading it. This article is about protection from a pathogen using you as an incubator or a host.
The old story goes that these thieves that would steal from plague-ridden people were in court and the judge said "if you can tell me how you were able to get so close to these victims without catching the plague, we will let you go" and the theives told them about using garlic and vinegar. So this formed the 3 thieves vinegar recipe and many variations of it.
If you are unable to get your hands on regular pharmaceuticals or are worried about what the pharmaceuticals may do, I highly suggest using raw garlic eaten every day especially before going in public. Also anything to keep your body in shape obviously exercise and good food but also maybe zinc(gluconate is a good salt) and vitamin d3 and iodine(which is also known to kill various pathogens and keeps the Thyroid working)
Stay well folks.
