honestly usually young animals who are infected with rabies show symptoms much quicker and die quicker than adults. I think the incubation period is 20 something days in a person from time of infection. - I know I had to have the rabies vaccines last year when I was bitten by a 1/2 wolf dog that was late on rabies and bit without reason.
Dog didn't have rabies - but they immediately gave me the first shot and 2nd shot because of 1. my description of his unprovoked attack and odd behavior and 2. because A/C reported he was 16 months late for his vaccine. SO - I got my shots while the dog was quarantined for 14 days.
I personally would pick up and take home a baby skunk - but being as knowledgable about animals as I am - as I'm curious for anything animal - always have been - I would 'quarantine it' myself - no one but me interact with it and keep adequate gloves and sleeves on at all times - so I couldn't be bitten and scratched thus being infected - and I'd only be putting myself at risk.
I have picked up dozens of stray dogs and cats of all ages and breeds and sizes - squirrels, possums, a young raccoon, bottle fed a baby fox for a few days, an owl for a week, and a bat for a few days (fox, bat, and owl - I had to care for till someone from elsewhere in the state could come and get them for rehabilitation). SO a skunk wouldn't be at all farfetched especially since I've heard of them being such good pets.
Rabies in animals is tested by 10-14 day obersvation which they tend to do in the case of animals and lower risk rabie carrier cases as is law - or if the animal is already/or starts showing symptoms or was a high risk (never been vaccinated - was in an outbreak area - etc) it is terminated immediately and a brain sample is sent to the lab for testing - this is 100% accurate.
Humans : I've never heard of an observation period in humans .
The usual wait period I've heard of is 72 hrs tops - the more severe the bite the sooner they give it to you - or some A/C / hospitals will give right away - especially since now its 1-2 shots usually 2 times - a week apart and you get it in the arm now.
Now I may be wrong - but this is what I've been told and have researched after I was bitten.
