Men can have the virus and transmit it without ever having an attack themselves. This I know personally. I got it from my husband just before we were married. It came on almost the next day, and repeated aabout every 3 or 4 weeks.
Then I learned about magnets. Sitting on them for about an hour a day will relieve symptoms indefintely. I also used a zapper and then really sent them into remission. I dispensed with the magnets. However stress will give the virus and advantage and they make the most of it.
