Yes, I had Lyme Disease (or possibly Rocky Mountain Spotted Fever or Colorado Fever if I recall what the doctor said correctly) that I got from a tick on a camping trip in the Glacier National Park (U.S.) some years ago. I developed a high fever, chills, the whole bag, and had the typical "bulls eye" around the tick bite site and was dragged off to a hospital in North Dakota by my wife. They did blood tests but because these diseases are endemic in the area they did not wait for the results and immediately put me on a massive dose of an antibiotic which was used for any of the above diseases. Within a few days I was fine and have had no re-occurence of the disease in the ensuing years. After we returned home, I mentioned the experience to a friend and it turns out his neighbour had been horribly sick since a camping trip to the states and the doctors here were unable to diagnose what was wrong. I asked about the "bulls eye" and it turned out she had a really good one on her thigh. After much arguing, she finally forced her doctor to check for Lyme which it turns out she had, however, because the treatment was delayed for so long she is apparently still suffering from various side effects of the disease and will likely be for the rest of her life.
The warning here of course is that quick aggresive treatment is needed which is standard protocol in most of the states where the disease is common. The problem in Canada, at least in Eastern Canada, is that the disease is relatively new to us and our doctors have no experience with it, so in many cases they misdiagnose it as a flu type sickness. Its not something they can really be faulted for in my view, but if you have any indication that you may have had a tick bite and have the appropriate symptoms (check out the web for possible symtoms), absolutely insist on a test for Lyme Disease and, if possible, insist on getting the necessary antibiotics (I know, easier said than done).
Sorry for the long post, but I thought the info might be of use since Lyme Disease is now found in parts of Ontario and Quebec. As an aside, that 4 hour visit to the hospital in the Dakota's reminded me of the importance of extra medical coverage insurance - the final bill for it was $800+ U.S. when the US dollar was worth a lot more than the Canadian $.
