This is, as you suspected, that you are surrounded by this virus by all in your family. So this is an energetic resonance aligning with the energies of your family members and this created a bridge energetically, allowing the flux of energy to affect you vibrationally and make you more susceptible to the condition within your dear wife. This enabled the organisms to gain a foothold because it weakened you sufficiently for that to happen. So even though you were praying to have protection from outside sources of this kind, your wanting to be in harmony energetically with your wife lowered your vibration in this case and it made you vulnerable enough for the organisms to take root. This had the assistance of some prior karma as well in making your respiratory tract of particular vulnerability. This you know already, and will only improve once the karma is fully cleared from the circumstances that created this vulnerability in the first place. That will happen down the line but will be some time yet to be fully effective.
