Why Do People With Lyme Disease Not Catch Colds And The Flu?

So, as I write this I’m living in a house full of sick people.

Completely surrounded by influenza.

And contagious germs.

Caring for all of my ailing family members.

And I’m thankful for one thing Lyme disease might be good for….preventing me from catching colds and, in this case, the flu that otherwise “healthy” people get.


Ever since I’ve had Lyme I can be surrounded with a highly contagious illness, but over and over rarely, if ever get “sick”.

If you have Lyme, you know this is a small consolation considering everything else we deal with, but each little thing helps, right?

I mean, we may end up going to the doctor, emergency room, or hospital for a number of other Lyme-related health problems, but if I can bypass the colds, flu, and other assorted viruses out there….I’ll take it.

For now anyway.

Interestingly, a friend who has Lyme told me her doctor was encouraged when she started catching colds and viruses her children would catch at preschool. He said this was a good sign.

But why, I want to know?

Does it mean her immune system is beginning to work like it’s supposed to again?

Why Do (Some) People With Lyme Disease Not Catch Colds And Flu?

I’ve researched this strange phenomenon online and have found many fellow “Lymies” who have the same experience. But I’ve had a hard time finding any concrete explanation for why this happens.

So if you know can you please share with me? 🙂

We’re told by our doctors that our immune systems are messed up, so I’m guessing this has a lot to do with it.

But is it because our immune system is so weak and worn down from trying to fight the Lyme and co-infections?

Or perhaps our immunity is in overdrive and simply wipes out every invader that comes close. But, if that were true, would we even have Lyme in the first place?

Or, here’s another thought. Because many of us have felt like we’ve had the flu every day since we were infected with Lyme disease maybe we can’t recognize a “little” cold? (I’m not implying a cold is little, just using it as an example.)

So many questions. Please help!

As a sidenote, I’ve read on some message boards that people with MS and a few other autoimmune conditions experience this same crazy phenomenon.

The Takeaway

If you have Lyme or know someone who does, do you still catch colds and other illnesses or not? Have you read or heard a good explanation for why this happens?

Please share your thoughts and opinions below in the comment section. I’d love to hear what you have to say! Hopefully we can all help each other figure this out. 🙂

  1. My doctor explained a lot of the pain, etc. in Lyme is from inflamation. When our immune system is overactive you get a lot of the Lyme (& autoimmune) symptoms. It’s only recently that I’ll feel like I am catching cold/flu & the next day it’s just the “normal” bleh.

    1. Hi Claudia,

      Thanks for sharing your experiences with Lyme. While I’m never glad to hear that someone has Lyme, it certainly helps us all when we share what we’ve learned and what we’re going through.

      I’ve heard this about the Lyme pain being caused by inflammation too. Isn’t it crazy how our immune system can show up in this way, causing all the autoimmune issues, but then when it comes to catching the flu….nada?

      So do you feel like your health is improving overall as you’re beginning to catch cold and the flu a bit?

      Thanks again for reading the blog and sharing your thoughts! I hope you’ll be back soon!



  2. Hi Kim,

    Thanks so much for sharing your experience!

    I’ve never heard it explained this way, but it does make sense to me. So do the “sick” germs just accumulate inside us and add to the toxic load since we can’t fight them off?

    I’m so happy you stopped by my blog and hope you come back very soon!

    Also, I hope you’re making good progress towards healing from Lyme and feeling better! Please keep in touch!

    Sending you hugs!

  3. Hi, for decades I never got a cold or a flu, at least that’s what I thought. What I was told is that I never got the symptoms of a cold or flu because the symptoms are your immune system working and your body fightingoff a cold or flu. So I guess since my immune system has been compromised from Lyme it isn’t working so the symptoms don’t appear. Does that make sense?
