There are at least 100 active viruses with similar symptoms labeled as the common cold. My understanding is that healthy people tend to have a high degree of immunity to a particular strain they have come in contact with, for at least a few years. If someone gets "the cold" multiple times in a year, they are almost certainly getting different strains.

Also the flu has fewer dominant strains, and reinfection still common, especially for people already at higher risk or compromised immune systems. But yes, Chances of reinfection should be lower than initial infection, but are non-zero, and while your body keeps you symptom-free while fighting off the reinfection your still, short term, a carrier.
