Not exactly. It prints exactly it's own source code as output but it doesn't run it again. You can run a quine output manually as it's by definition the same code that printed it but it lacks the ability to keep executing continuously like a worm virus would require. I guess you could make a worm virus that's also a quine but that would be a whole other problem.
