Can rabies virus survive and still be infectious if left on plastics,metals, or water for 7 days?

No: Rabies can only be transmitted if infectious material ( tears, saliva, neural tissue, cerebrospinal fluid- brain fluid) of a rabid animal contaminates mucous membranes, open wound, bite , scratch of a human. Even blood and feces( stool) of a rabid animal is not considered infectious if a person is exposed to them. (Source : Pediatric Red Book)
