does this look like the beginning of chickenpox?

Hey guys, so my son was in the ER all weekend with a high fever but he tested negative for covid, RSV, the flu, and pneumonia. we haven’t changed anything in his diet or his usual soaps or lotions. tonight his whole belly and back broke out in these red spots and it started spreading down to his legs.

my camera quality is awful, but the spots are barely raised and he doesn’t seem to be too itchy yet.
