Lyme, especially Chronic Lyme is a political can of worms in Canada right now. I think in the US too. With any luck this will just point to where the can of worms is without getting anywhere close enough to it to cause a ruckus. However, there are a few things worth pointing out about things like maps and other charts for where Lyme is prevalent.
One of the main problems with Lyme is that the only (government - as in Canada and the US) recognized testing for it at this time, has a very high false negative rate. Depending on which study you read, in over 60% of the negative results the person actually does have a Lyme infection, only the infection does not show up in the blood work. The official line the medical community takes in my part of the world is that the test has roughly a 45% chance of reading false negative. Also, an interesting sidenote is that the tests are for the Lyme infection most common in the East, the other 2,000 known strains of the infection do not yet have a test that is officially recognized by the entire healthcare community.
Given that there isn't a universally recognized accurate test for the infection (there are more accurate tests, they just aren't accepted by everyone), the diagnosis of Lyme is usually a diagnosis of exclusion. Is it cancer, nope, is it a flue, nope... not all this other stuff, then the only thing that is left that fits these symptoms is Lyme. If it responds to Lyme treatment, and it isn't this long list of other things then we will write it down as Lyme.
That's all well and good; however, given that doctors are individual people and prone to individual biases based on their training, external pressures, and past experiences, some doctors are more likely, and others less likely to diagnose a Lyme infection.
There are lots of other issues, like the current campaign against giving humans too many antibiotics as it is the main cause of superbugs (mumbles something about antibiotic abuse in CAFOs, cough cough)... basically they all add up to a huge controversy with two distinct sides: Officially sanctioned government recognized criteria for diagnosing Lyme and the other extreme that shouts loudly about the lack of research and funding into this pandemic (their word) which has a much broader criteria for diagnosing Lyme infections. Basically what happens from this is that to prove their point, they tend to stray as far from the middle ground as possible. For example, in my province, the party line is that we have 2 people per year infected with Lyme (chronic or otherwise) and the other side saying we have over 20,000 per year. When in actuality, if it wasn't a political quagmire, we probably have about 400 to 1,000 actual cases of Lyme (the numbers in this last sentence are (partly) my opinion based on way too many hours reading and talking with health professionals and biomedical ethicists).
What's this have to do with the pretty colours on the map?
Paul, if you don't know yet, I totally respect you and your right as owner and dictator of this site. Feel free to tell me where to stick my opinion if I go too far here.
That map and the site you link to has an obvious bias towards the government sanctioned party line regarding Lyme infections. Following some of the links, you can see a strong connection to the CDC. The makers of that map are probably using a very choice selection of the data available when deciding what colours to paint their map. It may be beneficial to check out the other side of the argument before you dismiss Lyme as being something to worry about.
That didn't get too political did it? I tried not to vomit my personal bias all over the post. Hope the ticks didn't get you too badly.
As for tick control. Chickens are awesome. They love munching on ticks. Depending on the tick, the ones in our area generally require spending some of their life cycle on mice/rats and/or on deer. Discouraging rats/deer from our main area has seriously reduced the number of ticks we see. Having grass munchers (sheep) take care of long grass helps reduce ticks and mice (no where to hide). The chickens sulk at the lack of ticks, but hey, they are chickens. There are plenty of other bugs in the grass.
