Is Jeremiah a typo for Jericho?
No...
Jeremiah is a 2 or 3 season series. The backdrop is a military developed, contact spread, virus that kills everyone puberty age (11 to 12) and older. All the cities and infrastructure has gone to complete rot because kids didn't know how to maintain any of it. All world gov'ts had completely collapsed into local bully fiefdoms. For about 10years the kids pretty much lived on canned food scavenged throughout the burning cities. Many infants died as orphans and under the care of siblings. All fuel and batteries are gone.
Jeremiah picks up approximately 15years later. Its really the story about rebuilding technology, society, and order. There's more to it than that, but I don't want to ruin the joy of discovery.
