It’s actually highly unlikely to catch the same cold twice. Colds are caused by viruses, and when your immune system fights one off, it builds up antibodies to it. Even if you encounter lingering viral particles from the same cold strain you battled before—on your coffee mug, your toothbrush, or via a cough or a sneeze from someone nearby—you’re probably not going to be infected again.
While you’re immune to that particular cold virus, you’re not protected from the more than 200 other viruses that can cause the sniffles.
