The common cold incubation period varies greatly from one person to the next. Symptoms can appear in just a few hours or as long as 10 days after exposure. The average incubation period is one to three days.
Shake hands or use the telephone right after that sneezing secretary, then touch your eyes, and you've got it, babe. Depending on the specific germ, the incubation period is between 12 hours and 5 days, usually 48 hours. To answer your question, the common cold is contagious between 24 hours before onset of symptoms until 5 days after onset. Like everything else this varies depending on the organism, but that's a pretty safe estimate.
