Understandable thought. In fact, we used to close all wounds on the battlefield during early wars. But eventually it became clear that closing the wound just traps in bacteria. Bacteria are just like us. They like warm wet places. So now standard of care is to leave infected wounds open and they heal from the bottom up. Best thing for a wound is to be draining and not accumulate.
