I think only conspiracy theories are the answer to your question at this time. I'm not the conspiracy type of guy but what the heck. If you want a wild conspiracy, i'll give ya one.
If you look at where lyme mysteriously started back in the mid 1970's(lyme connecticut) it just seems odd. There is a biowarfare lab nearby known as plum island. This lab was extremely active during the cold war in an effort to develop bio-weapons to fight the russians, should that day come. So how do you think these guys would act if something accidently got out. The orders would come from the top(cdc etc) and work their way down to the family dr level. If i was them, i would act as if lyme does not exist. Act as if it is hard to contract and easy to treat. Keep the numbers of reported cases low with many innacurate tests that usually come out negative. That way the regular population cannot cause an uproar and demand compensation. This would open up a can or worms if we knew how many people really had it and how widespread it really was. What do you think other countries would think if they found out this creature started here in the united states and is spreading rapidly around the world. Now you would be talking about some serious compensation to entire countries instead of just some american citizens. Oh well, there's a wild conspiracy for ya.
If doctors can tell most of the patients it is all in your head and keep the numbers low. Attention and investigation into this disease will not be drawn. It is easier to throw these sufferers into fake categories like chronic fatigue, als, parkinsons, multiple sclerosis, rhematoid arthritis, fibromyalgia etc.
I myself was thrown into the multiple sclerosis category in the beginning. But wouldn't you know, long term antiboitics and antimalarials cured my multiple sclerosis. I love when i go back to visit the neurologist and tell him how awesome i'm doing off generic overseas antibiotics.
I once told my shrink (yes I have one - even though some of us have LD it doesn't mean we don't need a shrink - haha) that if even 1/10th of the conspiracy theories about
LD are true... "I'm screwed"... which means "we're screwed"... AHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!
