The connotation of the term 'viral' has changed quite a bit.  Viral 
marketing for example has - at least for those initiating it - a quite 
positive appeal.

The ODbL applies to all OSM data everywhere - however the share-alike 
requirements of the ODbL only apply if the data is publicly 'conveyed'.  
Keep in mind though that this includes any produced works (like map 
renderings or other illustrations created using the data) - if a 
derivative database is used in producing such illustrations this 
database is subject to the share-alike requirements.

And note if you (as indicated in your initial inquiry) intend to license 
this derivative database or a produced work to a third party that is 
already a public process under the ODbL.
