A recent publication shows that the percentage of ticks infected with Bb in our area of Canada is 10-12.5%, and therefore this is "low" and no big deal!

So, does anyone know whaere there is information about percentage infection rates?

For example...in high risk endemic areas like NJ, what percentage of ticks are infected etc.?

The risk maps published by the CDC have definitions on them.


They define a medium risk as a tick infection rate of 4%.

i believe that i read a few articles online that stated 30-50% percent, depending on the area you live in.

CDC lies lies lies...


and unfortunately its not just by Ticks alone that this is spread.


Here's an official link for NJ, and its outdated, surely its more by now.

http://www.cdc.gov/nasd/docs/d000901-d001000/d000961/d000961.html

This is what they say on their web site...

"About 25 to 50 percent of the deer ticks in New Jersey (depending on where they are found) are infected with and able to transmit Lyme disease."


a darn shame that its almost 2009 and still no cure and more lies from them...

if our government really wanted to find a cure for this, they would.

whats a few billion less for them to make a couple less rockets to blow up stuff,
its the war machine and the crooked ceos of car manufacturers that get the bucks...
instead of saving people's lives with a living organism which can be killed.

You can find individual studies normally.. if they have been done for specific areas.

Here is part of an older one... as an example. Don't know if that link works?? Just data I had in an old file.

BTW- A study ... MY translation- Canada was upset with USA for allowing birds to come back across the Canadian borders (migrating season) full of OUR infected ticks.

Might have been a goose study?? I believe it had some figures in it too.

My old files didn't "convert" properly... but this MAY be the title and info for that partial list above. Credit where credit is due.

BTW- My notes indicated... after reading the study...

21 sites in the USA collected ticks... from 9 different states...

NC, SC, PA, CT, NY, MA, RI, NJ, CA and Canada

Lowest infection rate... zero

Highest rate- 81.1 %- Eastern Shore of Maryland

Average rate- 34.2 % infected

Here's the US Lyme risk map and some additional information. I don't see the definitions for the different risk categories here. This is on one of the maps.

Oh god, this is all inaccurate! There are millions and millions of ticks,and they probably sampled a small population of them and then did the testing wrong and hacked the data so its beneficial for tourism.

Don't forget ticks are not the only 'vector'.

I think many (if not most) people end up with coinfections from mosquito bites.

I would check with the State Health Department.


I just read the report for NH from 2007 and over 50% of the ticks sampled in several counties were infected with the bacteria causing Lyme disease. This was in southern NH.


They also said that reported Lyme cases in NH DOUBLED from 2006 to 2007. I'm curious to see next years report.
