Work place allergies

I was in on Saturday and Sunday. No allergies. This morning, I arrived at about 7:20 and felt fine until 10 minutes or so after 8am. The only difference in the office area between the weekend and today is the addition of people.

And, since I suffer less from my allergies if I keep my office door closed and leaving our suite relieves my symptoms, I am left with the conclusion that I'm allergic to something the people bring to the office. Since I don't believe one can be allergic to a person, it must be something "value added" like perfumes, colognes, fabric softeners, and other generators of gasses/particles in the air.
