[The Last of Us] What ever happened to the military, government and society?

In the beginning Joel is living in a protected zone with a lot of signs about quarantine, but whatever happened to the government and military? did they just dissappeared? dissolved into factions and smaller groups? why did radio broadcasts and other communications stopped? Did the disease spread overseas or is America under quarantine?

The spores are airborne and change people into murderous carriers. That makes quarantine zones and the like practically unmaintainable. All it takes is a few spores crossing the boundary and quarantine zones turn into meat grinders.

The population simply got decimated to the point where there's so few humans left that they can live in small isolated pockets that can be defended and kept clean.

By the time the population has been reduced by that much, there's no real government or military left.
