The Carar disease is a bacterium. Bacteria do not mutate. This is why antibiotics work.

You contract Carar once, your body (with a little help) fights it off, and now you can't contract it again.

If Carar was a virus, it would be much more dangerous, because viruses mutate. This is why (if you're not hygenic enough) you contract the Flu virus every year. It mutates. 2016's flu is not the same as 2015's flu. Your body knows how to fight 2015's flu, but not 2016's.
