Drinking alcohol decreases your immune response. A little bit is no big deal, but essentially, the more you drink, the more prolonged your cold will be.
broadbill is right (i.e., most colds are viral). However, if you're expelling a lot of mucous, you might take extra precautions not to let any get in your wort/beer/equipment. In addition to the virus, your mucous will carry a variety of bacteria (normal flora or not).
