As members and others have identified, I think there are levels. If we remove level 2, it will give us this at least for level 3 and level 4, but by and large, if we know about them, they're already under the regulatory regime.
My concern for the potential risk to public health is in the level 2 labs that we don't know about and that aren't under some kind of regulatory regime. If we don't include them, that will leave a big gap, in my view.
