[CT Birds] OT - Deer Ticks

     Thank you for sending the article to the list, I hope everybody reads 
it.  I have been reading about Powassan and other tick borne diseases since 
September and would like to add a few things.  Ticks become active at 
temperatures above 35 F.  In a very carefully controlled laboratory 
experiment, Powassan disease was transmitted from an infected tick to a 
mouse after attachment for 15 minutes.  Most victims report not being aware 
they had been bitten.  There is a delay in seeking medical attention because 
initial symptoms mimic the flu.  A tick can carry more than one illness.  It 
is imperative to identify the illness and treat the patient for any and all 
diseases or viruses.
The real problem, as the article mentioned, is correctly identifying the 
disease or virus affecting the patient.  The time it takes a clinical 
laboratory to reach a conclusion is time depriving a patient a recovery.
     A virus isolate test, is one where a piece of corduroy, one meter 
square, is dragged across the ground and then inspected for ticks.  These 
ticks are then analyzed for viruses etc.  Using this method, Powassan virus 
has been discovered in Connecticut, particularly in northern New Haven, 
Branford, Lyme and an undisclosed site in NW Connecitcut.  To date, there 
have been no confirmed human cases of Powassan in Connecticut.  Nationally, 
the total of confimed cases since 1958 are low.  That's a good thing.  With 
a 10 -15% death rate and lingering neurological damage for those who 
survive, that's a bad thing.
     It is time to practice active prevention LIKE NEVER BEFORE.  Checking 
yourself after a hike isn't good enough anymore.  A fifteen minute 
transmission time says you should check yourself during a hike every fifteen 
minutes, and once more after the hike.  Starting this year I will wear long 
pants tucked into boots and use abundant amounts of product containing Deet.

     This is the rough outline of information I have found.  By writing 
this, I am not attempting to stop all birding in Connecticut but to prolong 
it, providing preventative measures are followed.  Please be careful 
outdoors and especially birding in 2014.
