How to say "incidence" in Japanese
Choosing the right word
- 発生はっせいnoun, suru verb, intransitive verbCovers incidence as occurrence: something arising, happening, or breaking out, such as a disease or an accident. It names the event's coming about, not a count of how often it happens.
- 度数どすうnounCovers incidence in the sense of frequency: the number of times something occurs, rather than the event itself. Choose this when the English word is about how often something happens, not whether it happens.
Use 発生 for incidence as the occurrence or outbreak of something — whether it happens — and 度数 for incidence as frequency, the number of times it happens.
