Continental countries that share land borders with other countries have a hard time suppressing the virus because someone infected can just cross the border, which they can do even if borders are officially closed by crossing ilegally over land.
That's why I think that for these countries the pandemic will last either: Until the vaccine is developed and deployed in large quantities to inoculate the population or when herd immunity is naturally achieved through the deaths of a large number of people.
In certain regions of the world fatalities appear to have been high enough to develop some herd immunity: in New York 20-25% of the population already developed immunity to the virus. In other regions that were even more severely affected such as Guayas in Ecuador, Madrid, and Castilla La Mancha in Spain. I think that herd immunity has already been mostly achieved. Which can be noted as death rates have quickly declined in those places:

It would seem the only thing that could be a catalyst for herd immunity would be a constantly increasing number of infected who recover (create the necessary anti-bodies) whether they were symptomatic or carried the virus unknowingly without symptoms...
(Although, since I know little about herd immunity, I don't know how a certain number of recovered could effect it either! Unless anti-bodies are contagious just like the virus is... but I never heard of anti-bodies being communicable.)
