Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'сонная болезнь' (sleeping sickness) which in everyday Russian refers to African trypanosomiasis. Specify 'энцефалит летаргический' or 'болезнь Экономо'.
- Avoid a direct translation like 'болезнь экономики' which would mean 'disease of the economy'.
Common Mistakes
- Misspelling as 'Economy's disease' or 'Economic disease'.
- Confusing it with modern chronic fatigue syndrome or narcolepsy.
- Using it in a contemporary medical context without historical qualification.
