allergies

Why do people start ittiching there noses, sneezing, and even get rashes on their faces, when I am arround them. For years I thought it was smell, but I know thats not the case. This dose not just happen when I'm close to others, it also happens from distant. Why dosent everyone get sick, sometimes only 1 or 2 out of 5 people will get sick. PLEASE

Do you wear cologne,use body powders, special soap?
Maybe the smell of something you're using is causing a reaction.
I sneeze and cough alot around a few people at work only because of the smell of their perfumes and potpourri they have on their desks, it irritates my sinuses.
