ascariasis
Low (C2)Formal, Medical/Technical
Definition
Meaning
A human disease caused by infection with parasitic roundworms of the genus Ascaris, typically Ascaris lumbricoides.
The state of infestation or the medical condition resulting from ascarid worms, which can cause intestinal blockage, malnutrition, and respiratory symptoms during larval migration.
Linguistics
Semantic Notes
A mass noun; used without an indefinite article (e.g., 'diagnosed with ascariasis'). It refers to the disease state itself, not to the individual worms. Belongs to a set of -iasis/-osis terms for parasitic diseases (e.g., schistosomiasis, filariasis).

Learning
Memory Aids
Mnemonic
Think: 'ASCARIS' (the worm) + 'IASIS' (a disease state) = 'ASCAR-IASIS' – the disease you get from Ascaris.
Conceptual Metaphor
INVASION/INFESTATION (The body as a territory invaded by parasitic organisms).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'аскаридоз' (the correct translation) and 'аскаридиоз' (a less common variant).
- Avoid calquing as 'аскариаз' – this is not standard Russian medical terminology.
- The English term is a mass noun; the Russian equivalent 'аскаридоз' is also uncountable in standard medical usage.
Common Mistakes
- Pronouncing it as /æsˈkærɪəsɪs/ (wrong stress).
- Using it as a countable noun (e.g., 'He has an ascariasis').
- Confusing it with 'ascaridiasis' (a synonym) or 'anisakiasis' (a different nematode infection).

FAQ
Frequently Asked Questions
No, not through direct contact. Transmission is via the faecal-oral route, typically through ingestion of eggs from contaminated soil, food, or water.
It is most prevalent in tropical and subtropical regions with poor sanitation and where human faeces are used as fertiliser (night soil).
Dogs and cats can get similar infections from roundworms (e.g., Toxocara species), but the specific term 'ascariasis' is usually reserved for the human disease caused by Ascaris lumbricoides. Veterinarians may use 'ascarid infection'.
It is treated effectively with anthelmintic (anti-worm) medications such as albendazole or mebendazole. Reinfection is common in endemic areas without improved sanitation.
