There is no doubt that systemic candida can mess you up beyond belief, but have you considered that you have heavy metal poisoning?
If you have candida or some mold in your lungs, that could cause respiratory contamination although truth be told we are constantly breathing in these spores anyway. If you have fungal dermatitis this can also transfer through contact adn bedding, but these are all superficial contamination that we are exposed to all the time. The real issue is when candida gets a hold in your intestines. So long as your partner has a healthy immune system, stays away from Antibiotics and heavy metals (basically everything that causes candida overgrowth to begin with) then I think she will be okay.
