I'll try that one first. The legislation concerning level 3 and level 4 pathogens is absolutely required. And if people are not meeting the standards there, they shouldn't be working on those organisms because of the risk to the laboratory workers and also because of the risk to the public.
For the level 2 organisms, they can also cause laboratory-acquired infections, so it's important that workers know how to safely handle them and have the appropriate equipment and training in order to do that, so they are less of a threat to public health overall.
I was initially concerned about the fact that the bill encompassed level 2 pathogens, but in discussions within the agency I've satisfied myself that this will have minimal impact on the ability for university research labs to do the work that we want to see them doing. And that can be accomplished through regulations, and the regulations around class 2 pathogens are going to be really quite minimal.
