Translation guide
A disease that is constantly present in a particular region or population. In Japanese, this is most commonly expressed with 風土病 (ふうどびょう), but other terms exist for specific contexts like endemic infections or local diseases.
A disease regularly found in a specific geographic area or population
The standard term for an endemic disease, emphasizing its connection to the local environment and climate.
Malaria is an endemic disease in many tropical regions.
Literally 'local disease', used similarly to 風土病 but can also refer to diseases prevalent in a specific locality, not necessarily tied to climate.
That village has long had problems with endemic diseases.
Loanword from English, used in technical or epidemiological contexts. Less common in everyday speech.
Dengue fever is endemic in this region.
An infectious disease that is constantly maintained at a baseline level in a population
Both mean 'endemic disease', but 風土病 emphasizes the relationship with the natural environment (climate, geography), while 地方病 simply means a disease prevalent in a specific area. In many contexts they are interchangeable.
In casual conversation, you might explain the concept rather than use a technical term. For example: 「その地域にずっとある病気」(a disease that has always been in that area).
Measures against endemic infectious diseases are urgently needed.
