If we followed the South Korean model from the jump we wouldn't be in this predicament.
I still think the contagion will have slowed down drastically by July-August, but the only reason why it could linger around & continue to spread is because of the initial Governmental negligence & lack of urgency from the start.
When this thing first touched ground in the US, all port cities should've been locked down & quarantined, obviously, I'm certain most in the Gov never expected or completely underestimated the magnitude of the potentiality of this thing spreading like wildfire, but overall we were still too late in being vigorous in taking precautionary measures.
With that said, I still think eventually we'll get it contained to being manageable, the question becomes what happens if it comes back in the fall if it continues to mutate & spread? I think the toughest part we're going to have deal with is as a country, we pretty much are going to have accept the fact is that a lot of people will probably get it & spread it to one another asymptomatically.
Hopefully there will be enough antiviral meds available to combat Covid-19 for the long haul, but there's just no way a country will remain locked down for 6 months+ if most people won't die from it & it as of now, has a fairly high recovery rate.
