Can You Catch the Same Cold Twice? Answers to Your Sick Questions

by Leigh Ann Otte

It’s that time again–hacking, sneezing, sniffling season. Fall. And even though the same old sicknesses come around year after year, we figured you may have a few lingering questions about them. So what have you always wondered about colds and the flu? Perhaps …

  • Why does your snot sometimes turn green when you get a cold? (Ew!)
  • Why do your muscles ache when you’re sick?
  • What’s the difference between the flu and the stomach flu?
  • What are clear liquids, and why are they so great for sick people?

And, per the fascinating title of this here post, can you catch the same cold twice? Here’s the answer to that one, from Shirley Tozzi, M.D., an infectious-disease specialist in Massachusetts:

Within a few days after you get a cold, your immune system begins producing specific antibodies that prevent the virus from infecting more cells. Once you recover, you’ll be immune to that specific virus. However, many viruses can cause a common cold, and you could still get infected from a different strain.

And here are the answers to the other questions, plus seven more: “What Does Green Snot Mean? 12 Cold and Flu FAQs.”

Happy fall!
