If you're exposed to someone near a cold, how soon will you return with sick yourself?

I would like to know approximately how long after exposure to a cold virus you will develop symptoms. How long do you remain contagious if you are sick beside a cold? Usually 48-72 hours after exposure the first symptoms appear.
Short term imperviousness develops after you get over it, but you can still confer it to others.
48hours
It also depends on your immunity height, you may not get sick at adjectives.
Lots of different viruses motive the common cold. If you hold previously been exposed to this faddy virus and developed immunity, you may never grasp sick. Notice how, as we get elder, we seem to own fewer colds ?
