I used measles, mumps and chicken pox because they are also viri. Back when I used to go to the doctor, he told me that every cold you get is a slightly different virus and once you've had it, you won't get that specific one again, but the rhinovirus mutates pretty regularly, so even if you get two colds in one season, they technically aren't the same virus.
Keep in mind that I am not in any way trained in medicine and I drink a lot.
An old friend of mine once said about me, "I never knew he drank until I saw him sober."And could very likely be drunk right now?
