Lyme is an onion, isn't it? Peel back one layer simply to expose another, and then another.
This "chronic Lyme " fiasco is a house of cards built on equivocation. If you toss out the name "Lyme" and replace it with Borreliosis, some of the difficulties recede. For instance, STARI would probably be acknowledged as Lyme. Same with B Miyamoytoi, athough that is really a relapsing remitting agent. There might also be a unified push to generate a diagnostic with enough sensitivity and specificity to be applied cross-species. If you live in Europe, you can get tested for b burgdorferi and b afzelli and b garinii. That's not true in the US. In the US the official government position is neither garinii nor afzelii exist in North America, so no one tests for them. So, Hey! Are you stuck in Albany or Dallas or Chicago with a raging case of neuroborreliosis caused by b garinii? Odds are you won't get tested for it; God knows what a given clinician will say you have.
Meanwhile, whatever species you are fortunate to be tested for, the 2T diagnostic protocol acts as a virtual built in governor, effectively assuring the number of reported cases stays low - even though it may be jettisoning thousands of false negatives into the streets where their condition worsens as the disease takes hold and strengthens.
As Valentijn pointed out, Chronic Lyme deniers should also consider the ever-growing assortment of tick borne diseases that include multiple forms of Borrelia and Risksettsia and viruses like Powassan and the Bourbon virus, and parasites like Babesia and other pathogens like Bartonella and Ehrlichia, all transmitted through tick bites, most without good diagnostics..Any one of these can leave in their wake individuals who are very very sick. When stuck with a clinician that doesn't know what to look for, wielding outdated poor tests to help misdirect and confuse, patients often just get slapped with the Lyme label without any proof it's Lyme - cuz maybe it's Miyamoytoi or Babesia or Bartonella. Shoot the poor bastard because he thought the disease came from a tick, so it logically would follow it's Lyme. That's what many clinicians would think if a patient stumbled in with an embedded deer tick. But there is an ugly need in some doctors and researchers, to denigrate the disease and vilify the victim.
The result? The old Lyme guard ridicule an entire patient community as never being sick with Lyme, even though the patients may have any one of several TBD pathogens, or even worse, multiple co-infections. And yes, even when they have Lyme despite tests which might indicate otherwise (most people don't know that the number of IgG bands can fluctuate over time; one month I might only have 3 bands positive, the next five - so in a space of two months I have gone from Lyme negative to positive, when I have been positive all the while.)
The final insult is when you focus on Lyme alone, when you drill down into Borrelia, the agent of Lyme and a) you reveal current diagnostcs are kicking to the curb many sick with Lyme, kicking them back onto the streets for failure to pick up the scent, and b) treatments don't work for far too many Lyme patients just with your garden variety Lyme. Why? Because the outer surface proteins of Bb are constantly shifting, fooling immune systems. Moreover, that little bug is expert at finding and digging into secure parts of the body, like the brain, where it is safe both from the victim's immune system, and most abx. The truth is, if Lyme isn't caught early, if it progresses to late stage disseminated, Lyme symptoms may grow entrenched and they can intensify and Bb can be devilishly challenging - if not impossible - to eradicate.
On top of all THAT, there are differences in species - with each species comes a unique set of properties and problems peculiar to that species. The same holds trues with strains. A 100 strains are out there in a multitude of ticks, outside in parks and ball fields and playgrounds and nature paths, but most Lyme test kits are built to look for a single strain, B31. Only one. (And even it has properties that help it elude detection and fool immune systems)
Over 35 species of Borrelia alone, at least five or so that are known to be pathogenic. And 100 strains. Spirochetes that shift their outward appearance to fool immune systems. Multiple severe pathogens that comprise TBDs, including a few that can kill you in short order. If you just mull on the permutations alone, just for a few minutes, I'll wager many will think twice before going for a stroll in the tall waving wild grass where they might pick up a bug that defies tests and treatments, and stamps its victims as malingerers and hypochondriacs.
But chronic Lyme doesn't exist.
