I need to know if colloidal silver kills the feline distemper virus

Also, one on my two kittens ust died of distemper, and he was drinking cs
for two days prior to his showing symptoms.  He drank 18 ppm silver.  I
believe he was already very sick when I got him, but he didn't show it. 
Anyway, after he passed away, I kept him and washed him and dried him in
preparation to burial and it took me three days to dig the grave.  He was
in a styrofoam "casket" for three days, and I took one last look at him
before placing the lid back and putting him into the ground.  His body
looked like a sleeping kitten.  There was no bloating, no smell, and
nothing else to view that would indicate he was even dead.  Why would
that be?  Is it because the colloidal silver really killed every bateria
in his body.  If so then why did he die?  
Also, I have another kitten that has been on silver for a week propr to
receiving the one who was sick and died.  He is showing absolutely no
symptoms at all, yet this is a highly contageous disease.  If anyone
knows the answers please let me know.  It is important to me. 
Thanks, I hope someone can answer my questions.       Deb
