コロナ

ころな
noun
coronavirus; COVID
1. coronavirus; COVID-19 (informal)
In everyday Japanese usage since 2020, refers to COVID-19 and the social impact of the pandemic. Used as a casual shorthand where English would more often say 'COVID'. The formal name is 新型(しんがた)コロナウイルス.

コロナの影響(えいきょう)で在宅勤務(ざいたくきんむ)が広(ひろ)まった。
Working from home spread widely due to the impact of COVID.

Originally short for コロナウイルス (coronavirus), but since the COVID-19 pandemic the word is almost always understood to mean COVID-19 specifically. The full formal name is 新型(しんがた)コロナウイルス感染症(かんせんしょう) (COVID-19).

COMMON COLLOCATIONS:

  • コロナにかかる: to catch COVID
  • コロナ禍(か): the COVID pandemic / its impact (literary; very common in news)
  • コロナ対策(たいさく): COVID countermeasures
  • ポストコロナ / アフターコロナ: post-COVID
  • コロナワクチン: COVID vaccine

NOTE ON USAGE:
コロナ may also appear as a brand name (e.g., the Mexican beer or the Toyota Corona car), but in conversation since 2020 it overwhelmingly refers to COVID-19.
