Probably more as these plagues seem to have outbreaks after they end for the next 50, 100, 200 years. And then the second outbreak is going to be the one that occurs in the 14th century, in the 1330s, 1340s, 1350s. This is the big one, the great plague, the black plague which we're going to focus on. But later on the plague is going to be back. It's going to be back in the mid 19th century to the early 20th century in China and India killing upwards of 12 million people. And there's even spotty outbreaks to this day, normally in the Sub-Saharan African region. And normally if we get hold of these people we can cure them.
