My Flashcards

Definition

Meaning

The process by which an organism becomes infected by its own pathogens or parasites, typically when they are transferred from one part of the body to another.

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

Semantic Notes

Primarily used in medical and biological contexts. The concept is specific and not typically used in general conversation. The 'auto-' prefix clearly indicates a self-directed action.

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.

FAQ

Frequently Asked Questions

No. Contagiousness refers to spreading infection to others. Autoinfection is about infecting oneself from one's own existing infection.

It is extremely rare. One might encounter a metaphorical use, such as 'the autoinfection of corrupt practices within the organisation,' but this is not standard.

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'.
