I don't think regular seasonal visitor has been called yet. In that article the CDC director is simply stating the one-off amount of time he expects the virus to be around for, not that it will recur every season.
The article doesn't have the full quote from the video. After mentioning community-based transmission, he goes on to say that "You can start to think of it like seasonal flu," which does suggest recurrence.
You're right, apologies. Incredible that the article left that quote out.
