How can a wound infection get chronic?


I mean, I’m aware bacteria can get/be resistant to some or most antibiotics. I’m also aware they can make biofilm to protect themselves.

But I can only understand this if it was inside the body, in a hard to reach place.

But if it’s on your leg for example, why can’t you just put antibiotics or sanitizer (which basically works like an sledgehammer on bacteria. I can understand you can’t use this inside the body) directly on the wound or scrape into the wound until all the bacteria are off.

I might be missing something, so thanks in advance for explaining.

What you describe….scraping into the wound is called debriding. Which would remove damaged tissue to expose healthy uninfected tissue. Washes with the cleansers you are describing and a combination of systemic antibiotics and you prevent the wound from becoming reinfected as it heals.

That said, to answer your questions even more simply. As you describe…

You can.
