You can't catch CFS. It has a genetic base, it isn't contagious. But there are so many undiagnosed illnesses and loads of non cfs illnesses get loped in to the cfs/me category. I've known people who think they have cfs and they ARE sick for sure but with something different as they don't meet the criteria and can do things no one with cfs can do. So......could be good news for you guys, maybe there is hope to get well.
I agree that ME/CFS in itself is not contagious. However we haven’t established a genetic link for sure, so this is all theory.
Although I agree that ME/CFS in itself isn’t contagious, the possible pathogen driving the symptoms can be transmitted from one person to another and cause systemic inflammation, systemic symptoms and immune dysfunction. This all depends on the pathogen, naturally.
Certainly was it ME/CFS that I had:
It started out as mild flu like symptoms, then came the intolerance to exercise shortly after. Later came the PEM which would take sometimes up to 3 days to kick in and leave me bedbound for at least a week.
I kept pushing with school and became worse and worse and eventually bedbound. I couldn’t speak for over 2 weeks or handle any stimuli. Not a single word. I was in a severe ongoing crash with constant symptoms. I had muscle pain, unimaginable brainfog, couldn’t handle light or a sound at all. I lost a lot of weight and was down to 45kg just from the inability to chew food. At first I would have hypersomnia, then it turned into insomnia. My EBV was reactivated alongside HVS-1 which is very typical for an ME/CFS patient. My mom had her CMV re activated alongside EBV. We both had developed POTS, and going to the toilet felt worse than a marathon. I fullfilled all the criteria on the CCC, which is the way most docotrs today diagnose ME/CFS. In fact, you cannot participate in most ME/CFS studies without being diagnosed through this criteria due to how accurate we must be when conducting well ME/CFS research.
How can E. Coli EPEC drive all the ME/CFS symptoms? Unfortunately the bacteria causing Lyme alongside other pathogens (EBV, CMV, enteroviruses etc.) are not the only thing that can hijack the immune system and host cells and drive these symptoms. Here is a very well put together paper by Dr. Amy Proal describing how different pathogens can drive ME/CFS symptoms:

ME/CFS is described to cause an immune dysfunction, it’s one of the few things we can say for sure about this illness.
Further: E. Coli EPEC also immune dysfunction in a numerous of ways, here is to name a few
Disruption of Epithelial Barriers
- EPEC adheres to intestinal epithelial cells using a structure called the locus of enterocyte effacement (LEE), which encodes a type III secretion system (T3SS).
- The T3SS injects effector proteins like Tir (translocated intimin receptor) and Esp proteins into host cells, leading to:
- Destruction of microvilli (attaching and effacing lesions).
- Increased epithelial permeability.
- Impaired barrier function that exposes the underlying immune cells to pathogens and antigens.
Why is this an issue? This can further lead to a systemic inflammation in the body along side a range of other symptoms such as fatigue, leaving you vulnerable to secondary infections etc.
This is something a lot of patients with ME/CFS struggle with
2. Modulation of Innate Immune Responses
- Inflammatory Signaling Suppression:
- EPEC dampens the host’s immune response by interfering with pathways such as NF-κB and MAPK.
- It secretes effectors like NleE and NleC that inhibit cytokine production (e.g., IL-8), reducing neutrophil recruitment.
- Immune Evasion:
- EPEC inhibits reactive oxygen species (ROS) production and phagocytosis, enabling it to persist in the host.
- Activation of Inflammasomes:
- While EPEC can activate inflammasomes, the response may be suboptimal, leading to inadequate pathogen clearance
This can again lead to a lot of inflammation, flu symptoms, fatigue, alongside malabsorption in the gut; which leads to deficiencies causing even more symptoms and immune dysfunction
3. Subversion of Adaptive Immunity
- T Cell Impairment:
- EPEC can interfere with antigen presentation by altering the function of dendritic cells and macrophages.
- Suppression of cytokines like IL-12 reduces T-helper 1 (Th1) cell responses.
- Chronic Immune Activation:
- Prolonged exposure to EPEC antigens may lead to immune exhaustion or tolerance, impairing adaptive immunity.
We know that also chronic immune activation is a huge issue in ME/CFS, I don’t think I need to say more
4. Disruption of Microbiota and Immune Homeostasis
- EPEC alters gut microbiota, which affects the immune system’s ability to regulate itself.
- Dysbiosis may lead to increased susceptibility to other pathogens and systemic immune dysfunction.
We also see signs of a disturpted gut microbiome in ME/CFS patients. We know that a messed up microbiome is not the driver of ME/CFS but rather a cause of having the disease. Again this fits everything to a T.
5. Impact on Gut-Associated Lymphoid Tissue (GALT)
- By damaging the intestinal lining and altering immune signaling, EPEC can compromise GALT function, impairing both mucosal and systemic immune responses.
This can cause systemic inflammation, and drive a bunch of systemic symptoms, it can also further lead to food allergies and intolerances to new things you didn’t have any issues with prior to the infection. This as well happened to me.
Clinical Relevance
The immune dysfunction caused by EPEC can result in:
- Increased susceptibility to co-infections.
- Delayed recovery from infection.
- Chronic intestinal inflammation in severe or repeated infections, which may predispose individuals to other inflammatory disorders.
These last few points are also very common in ME patients.
There is more to E. Coli EPEC than what I have described here, but the post would simply be too long. All I can say is it can drive all the ME/CFS both me, my partner and mom experienced
When we further explore the nature of some of these pathogens we can understand how they can drive a lot of symptoms and lead to chronic systemic inflammation alongside other issues in our body. It’s very interesting to dive into and further research is needed to understand the mechanisms of different pathogens, so we can more effectively test and treat them. As for now, science is lacking greatly in this department, especially when it comes to viruses and how they can affect our body.
