Will we need lifelong prophylactic use of Creator’s Antiviral Regimen even after the interlopers leave, given that so many people are carriers of harmful viruses or have a chronic virus caused illness?

This is quite likely to be the case. First of all there will be a very high percentage of people already infected. The interlopers will not take their viruses with them when they leave, so the consequence of what has already been started will need to be dealt with and for many, that means continuing of vigilance and an ongoing campaign to first contain the scourge and then to reduce its influence by decreasing numbers of viral particles, with the goal of reaching a vanishing point. That can take widely varying lengths of time and it will not be possible to know who is safely cleared and who might not be. There is also possibility of person-to-person transmission. Even though a very small probability, it could happen between life partners engaged in intimate relations in close proximity, as much through an alignment energetically to be in resonance with one another. That can increase a state of vulnerability for an uninfected person just by energetically wanting to align with their partner. That can bring negative consequences as well as positive, depending on the state of well-being of the partner. So again, having preventive care underway for everyone creates a safety net that could be very beneficial.
