Skin better than ever after antibiotics

Ok. So I traveled to Morocco recently and picked up a water born bacteria. I was absolutely sick as a dog for almost 2 weeks. Went to the hospital it was so bad. Was told I had an infection of the bacteria campylobacter. Took some heavy duty antibiotics to clear it up, which were successful, however my system is destroyed from the whole thing. However, my flushing is at an all time low. I know rosacea is rooted in gut health, and I’m assuming whatever bad bacteria that were looming have been eradicated. Anyone have any insight into what it could have been? And how to keep it from coming back? Could just be a fluke but somehow I don’t think so.
