Although it is unusual to leave all previous text
attached to an article in this case it may be
important to do so.
The Nat Geo piece credits:
http://www.cdc.gov/ncidod/EID/vol12no08/05-1526.htm
as the source for "passive transmission" but no such
statement appears to be present in the article. I am
wondering if they also found that some animals had dumb
rabies and confused infection from such an individual
with passive or casual transmission because of the lack
of aggression.
It is always interesting to following an emerging strain
and watch its evolution. What I can't find is why they
wrote "casual" in relation to the transmission.
