In a broader sense, it can metaphorically describe any self-perpetuating negative cycle or situation where a problem is caused or worsened by its own consequences.
Linguistics

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'auto-' as related to cars (авто). Here it means 'self-' (само-).
- Do not confuse with 'autointoxication' (аутоинтоксикация), which is a different, though related, medical concept.
Common Mistakes
- Misspelling as 'auto-infection' (hyphenated form is less standard).
- Using it to refer to any self-caused illness, rather than the specific transfer of an existing pathogen.

A classic example is with the threadworm (Enterobius vermicularis), where eggs laid around the anus are transferred to the mouth via the hands, causing reinfection.
No, it is a very low-frequency technical derivation. You are more likely to see the noun form or phrases like 'cause autoinfection'.
