We have a highly transmissible virus getting established in the blood donor system and seriously getting around. It needs to be stopped. Now we discover it can be transmitted by sex.
Worse it is also a likely unidentified vector for the disease that leaves you paralyzed.
All this means is that it needs to be tackled hard and eliminated. By that i also mean from carriers. This is not AIDS so it should be possible. We do not know how extensive it may become but we will far too soon.
Most victims merely get a rash that soon enough goes away. That means the best protection is to infect the whole population to provide blanket immunity and no possible birth defects or paralysis. We do not know enough to really do that though.
