>>1888005A thing here is, unless these viruses display themselves in any other way, for this phenomenon to be discovered, A-type infected and V-type infected would have to:
1. Meet
2. Have sex
3. Survive the transformation (not actually necessary)
4. Inform the authorities.
Also, is there any information on how the infection occurs? It doesn't even seem to be contagious, Mamori was not isolated right after she was diagnosed, but was allowed to mingle for about 10 years.
