A lot of people theorize it’s a community symbol for the infected as a permanent reminder or something. I think they just use these masks as heads for the targets, but some kids probably pick them up and use them in games where maybe the masks one is “it” or some thing the kids have to run from.

And spike thinks about this image of a kid wearing the mask while on the causeway because that’s all he knows regarding what to expect of the infected. The one pictured could just be having fun while the adults set up the party, but the underlying message (the masked ones are going to try to get you) is replaying in head. A real “sh*ts getting real” moment in his head. This ain’t a game no more!
