Infected Explained in The Last of Us
Short Answer
The infected are humans overtaken by Cordyceps, ranging from newly turned runners to armored bloaters.
Story Role
Infected matters because the infected are humans overtaken by Cordyceps, ranging from newly turned runners to armored bloaters. The detail is tied to concrete choices in Season 1 rather than functioning as a loose apocalypse glossary item.
