Based on the localized infection cases I see across the US and have been watching as well as the characteristics of the virus (life outside host/on surfaces, in air, the degree of asymptomatic transference, etc.), it's well beyond containment IMHO.
Travel isn't going to do too much to reduce infection rates alone. We need significant cultural changes to reduce infection rates, but I don't see that happening for a variety of reasons. This country isn't about proactive action and is all about reactionary action though, so we're just waiting for that reactionary threshold. Some preventative measures have been pushed but they're no where near aggressive enough at this point.
It will be interesting how this is handled in our modern cultural, current political and work culture, etc. I suspect it's going to be fairly nasty but certainly hope not. I've been advising my parents to stock up and minimize any outside interactions for awhile.
