Further Research suggest your correct. I'll have to check multiple sources in the future. http://www.cdc.gov/rabies/transmission/exposure.html
While we are on the topic of rabies transmission further research on the tab of my previous link but under ''the path of the virus'' tab instead i found this...Extensive studies on dogs, cats, and ferrets show that the rabies virus can be excreted in the saliva of infected animals several days before illness is apparent. Such extensive studies have not been done for wildlife species but it is known that wildlife species do excrete rabies virus in their saliva before the onset of signs of illness. The excretion of virus may be intermittent, and the relative amount of excreted virus may vary greatly over time, before and after the onset of clinical signs.
Would that indicate that we should never shoot these animals in the head or neck as their is always that risk or perhaps we just need to get checked after each season.
Its possible im being overly cautious, But the fact that rabies has such a long gestation period and by the time a symptom occurs your good as dead scares the bejessus out of me as i prepare to get my trapping license especially with coons as one of my primary intended targets.
