Have you noticed a slow, steady decline in your athletic performance? Or the onset of joint pain from seemingly nowhere? What about prolonged muscle soreness, needing longer periods for recovery, constant injuries, never feeling rested, blurry vision, shortness of breath, severe fatigue, or vertigo? Let’s explore what all of these symptoms have in common.
There are many possible causes and contributing factors, but one of the most underrated “performance enhancement” tactics I have seen work on my patients is investigating these symptoms for the possibility of chronic stealth infections, and addressing anything we find.
Read on to find out more in this three-part series about what stealth infections are, how they occur, why athletes may be at an increased risk, how these infections can impact your performance, and what you can do to take charge of your health if you are experiencing any symptoms of stealth infections—from mildly inconvenient to debilitating. Addressing the issue at the onset by recognizing changes in your health can help prevent a long, hard road to recovery, so let’s jump in!
Stealth infections occur when pathogenic—or harmful—organisms including certain types of bacteria and viruses enter the body and lie dormant, undetected by the immune system for weeks, months, or even years before they are “activated”, causing illness.
During periods of intense stress, injuries, or exposure to toxins like mold, immune system function takes a hit and these pathogenic organisms begin to opportunistically grow out of control. This is the point at which mild or severe symptom onset occurs. As the pathogen load increases in the body, symptoms may worsen or progress if the infection is not suppressed and regulated by the immune system.
The most common stealth infection is Lyme disease caused by Borrelia burgdorferi and its frequent co-infections, Babesia and Bartonella. (The term co-infections implies that two stealth pathogens were introduced to the body from the same source). Other organisms capable of causing stealth infections include Streptococcus, Mycoplasma, Ehrlichia, Epstein-Barr Virus, parasites, covid, and more. Some of these infections are so stealthy that people who test negative on blood work may still experience symptom relief when they begin conventional or alternative treatments, showing that testing is not fool-proof for stealth pathogens.
Some stealth pathogens are capable of residing on and inside host cells, while some have developed other mechanisms to “hide” from the immune system. For example, certain pathogens like the parasite Babesia and bacteria Bartonella can hide inside of your own red blood cells, while Borrelia is thought to change its cell membrane characteristics to avoid immune system detection.
Sometimes found in sticky “biofilms” within the body, stealth pathogens use these structures to help protect themselves from antibiotics and immune system recognition—think about the plaque that starts to form on your teeth when you go too long without brushing them, except deep inside your body. In addition to protection, these biofilms may allow different pathogenic organisms to share resources and survive longer.
The commonality linking all of these different stealth pathogens is that each of them can only flourish in an environment where the immune system is imbalanced already. Even if pathogens are under control with natural or conventional treatment, the symptoms often return with a vengeance. If the infection isn’t properly managed to prevent the conditions that caused it in the first place like stress, overtraining, poor nutrition, etc, it is more likely to occur again.
Additionally, these organisms are not evil, they are just responding to changes in their environment (aka your body), going from docile and dormant to pathogens on the attack when the conditions are right. This concept is known as pleomorphism (“to assume different forms”).
Organisms may “shapeshift” and their form and function can change due to a change in their terrain or environment.
While you can do your due diligence to protect yourself, exposure is essentially impossible to control, especially when traveling, working, being outdoors, or just generally participating in life. Lyme disease is often transmitted by ticks in the “nymph” stage, or ones that you can barely see with the naked eye. Most people who experience Lyme disease never even recall being bitten by a tick. Thus, it may be less important to focus on HOW stealth infections occur, compared to WHY (suboptimal immune balance), and how to prevent symptoms and diseases even if exposed.
Transmission of stealth infections originates with biting insects. The most common is injection via biting insects including ticks, fleas, mosquitos, lice, sandflies, and others. Ticks are the most common vector for Lyme and co-infections, specifically black-legged or deer ticks and lone star ticks. Research claims it takes 24-48 hours of attachment before a tick can transmit the bacterial contents of its stomach into the bite site, causing transmission of Lyme and co-infection organisms. While this may be the currently accepted science—as we have seen within the last few years—science can change quickly and majorly, so any tick bite should be investigated regardless of how long it has been attached.
Studies show 39-53% of people with Lyme disease (Borrelia) had at least 1 co-infection like Babesia, Bartonella, and others:
Co-infections can complicate the treatment of Lyme.
Co-infections can make symptoms worse or cause symptoms of their own [1,2]
Stealth infections originate with biting insects but can be transmitted to humans by various means, including:
There are many more pathogens than are named here—including H. pylori, Cytomegalovirus, Mycoplasma, Ehrlichia, Anaplasma, and more—but the microbes listed above are some of the most common stealth infections we encounter at Vagus Clinic every day.
A healthy body can have low levels of pathogens while the immune system and microbiome keep them in check. When the immune system is weak due to internal or external stress, these pathogens may multiply and cause increased symptom severity. This is also the reason why a person can feel good and bad intermittently since the pathogenic load goes up and down as the immune system attempts to eradicate the infection.
Borrelia, for example, is so stealthy that individuals who have weaker immune systems may not even experience the hallmark indicator of a “bull’s eye” rash after a tick bite. There are 20,000 - 30,000 news positive cases per year and over 300,000 people who are currently diagnosed with Lyme in the US. There are likely just as many mis- or un-diagnosed cases and only about 3 in 10 people experienced the stereotypical rash [5]. Those who don’t experience the rash also generally have no recollection of the acute phase of Lyme disease, which includes fever, flu-like symptoms, and chills. Lyme disease is often referred to as the “The Great Mimicker” because Lyme and co-infections have symptoms common to many other conditions, –ones that often don’t have a microbial origin–so most doctors don’t even think to look for hidden infections.
Oftentimes, a person whose immune system is strong enough to strong enough react immediately and present the “bull’s eye” rash will also be able to more easily overcome Lyme infections with conventional or alternative treatment. Those who don’t experience it may have weaker immune systems and be more likely to experience symptoms of mid-stage and late-stage Lyme disease months or years later.
To make matters more complex, stealth infections are often found alongside toxins like heavy metals, mycotoxins from mold, or environmental chemicals like glyphosate. Each one of these impairs the body’s nutrient status, immune system, detox mechanisms, and microbiome, making it easier for stealth infections to gain a foothold or vice versa for toxins to accumulate in the body.
The friendly organisms that make up your microbiome are part of your immune system and meant to help you stay safe from pathogen infection. The microbiome helps keep pathogens in check in many ways, including by simply out-competing the pathogens. Friendly microbes should be “crowding out” infectious organisms at all times—so they can’t gain a foothold and explode into large, symptom-causing colonies in the body.
*Note: My favourite probiotics to combat stealth infections and reset the gut microbiome are MegaSporeBiotic and HU58 from Microbiome Labs.
If the immune system goes down or our friendly microbes are struggling (due to antibiotics, toxins, stress, or poor diet), stealth pathogens have adapted ways to overcome detection and eradication by the immune system. They are truly smarter than we realize.
As you can see, stealth infections can clearly be a problem for anyone wanting to achieve peak performance—or even just have a good quality of life. The intention of this article is not meant to scare you from the outside world, but to empower you with knowledge and tools. This way, you can worry less about exposure—while still being cautious—and focus more on prevention and fortification of your system in case of exposure.
More than anything, it should be a wake-up call for you to keep your immune system and body in balance so your internal terrain doesn’t become favorable for these potentially destructive bugs.
