Dealing with a case of HFMD and was wondering how the viral infection targets the same specific locations on the body in most cases. Why is the rest of the body clear? How does the reaction isolate itself to the same extremities?

It’s no so much that it “targets” those specific areas but more that those specific areas are more prone to show the effects of the virus
The skin in those parts of our bodies are different to the rest of our body more easily develop blisters than anywhere else and because HFM disease causes blisters its on these parts that the blisters are most likely to develop.
The bumps on the outside of a virus basically act as a kind of key to unlocking the cell walls so they can get inside to replicate. Some cell walls are easier to penetrate than others with certain keys.
