Study Notes Spread of Wasting Disease
   By ANDREW BRIDGES 

   Chronic wasting disease is transmitted more easily than previously thought, a
   finding that complicates efforts to curb the relative of mad cow disease as it
   spreads in populations of deer and elk, according to a new study.

   [ The disease affects the nervous system and is marked by weight loss, 
     stumbling, tremors and lack of coordination. There is no cure. ] 
 
   Researchers who previously believed transmission from doe to fawn played an
   important role in its spread now say that's not the case. Instead, the contagious
   brain disease is ``remarkably efficient'' at spreading from animal to animal, new
   research shows. 

   The finding suggests it will be harder to control the fatal disease other than
   through the drastic thinning or eradication of infected herds, as has happened in
   parts of Wisconsin. 

   ``Unfortunately, that's what we're left with in the short term. In the long term, we
   hope something will come along,'' said Mike Miller, of the Colorado Division of
   Wildlife and co-author of the new study.

   Details appear Wednesday in the journal Nature.
