ADV can be spread through placenta of a mother to her kits, or through bodily fluids such as blood, saliva, urine, feces, etc.. It is though perhaps the virus takes a bit more than casual contact to contract....but since we do not know for sure, it is good to take proper precautions. The virus can live on inert things such as floors, etc for some time.
