Saxmar is correct. Insurance companies are part of the problem. Lyme treatment for 2-3 years is very expensive versus a simple 21 days of cheap doxycycline. Followed by some xanax, cymbalta or prozac maintenance when they tell you it is all in your head.
We don't know the real reason why it is completely ignored like it is. But if you look at a close cousin of lyme, Syphillis is treated for 1-3 years, Chlamydia pneumonia is treated for 2-3 years with multiple antiobitic combinations via the vanderbilt protocol. Look at Tuberculosis, treated with multiple drugs for 1-2 years, Aids treated indefinitely, Acne treated for several years with tetracycline type antibiotics. The list goes on and on. The facts on this site and lyme.net etc speak for themselves. Ask the actual victims, most of them have recovered from their former hell. But it took 1-3 years of multiple drug combinations in order to return to normal.
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.
