Oh there's definitely a supply chain issue now; we're not going to be able to re-stock anytime soon is my understanding. So there was absolutely a high degree of unpreparedness at many levels. However, we already nearly depleted our masks and we haven't even had a significant spike in need yet.
If people hadn't been stealing masks for their own personal use outside the hospital, we probably could have had our supplies last another few weeks, which is significant.
