Here is why you are all wrong about it being the norovirus, the nolovirus, the cholavirus, the chupacabravirus or anything else.
Think about it: OK, you say we got this from a highly contagious virus. So virulent was this virus that we all caught it from our food merely being handled by an unseen dirty person in the kitchen. A person we did not come close to, did not touch, etc. Then WHY did one among us who is married not give it to her husband? WHY did the Armeniac not become sick when he ate after me the next day? In fact, why would it be that not one single other person we know, not our boyfriends, siblings, co-workers, priests, lawyers, milkmen, pets, etc. ever get sick? Six days later and the only people who got sick were the FIVE PEOPLE WHO ATE THE ALBACORE TUNA AND NOT THE TWO WITH US WHO DID NOT!!!!!
