I'd be surprised if geographical proximity to a BLS4 made much a of a difference to what would otherwise be a rudimentary swab & routine inspection (if that was even done at all).

As Kristian Andersen notes, the background noise of flu season would surely drown out the weak signal of an unknown novel virus. Then to not only notice the weak signal but act on it so quickly to do primary research and characterise it as a novel virus within such a short timeframe?

Seems far less likely than simply the effect of poor operational standards.
