sudden start and spread of disease
A time when a disease suddenly appears and spreads quickly in one area or group of people.
用法パターン：
an outbreak of [disease] in [a place]
よくある間違い：
Learners sometimes try to use *outbreak* as a verb (e.g., *The disease outbreaked last year*). This is incorrect; *outbreak* is a noun. Use a structure like *The disease broke out last year* or *There was an outbreak last year*. Learners may also confuse *outbreak* with *infection*: *infection* is the state of being infected, while *outbreak* is the event when many infections suddenly happen.
類義語
epidemic (Usually suggests a larger or longer-lasting spread of disease over a wider area; often used more technically.)
|
flare-up (Less formal and can sound milder; often used for a return or sudden increase of a disease rather than a first appearance.)
対義語
containment (Refers to successfully stopping or limiting the spread of a disease, which is the opposite of an outbreak continuing or growing.)
|
eradication (Means completely removing a disease from an area or the world, the long-term opposite of a new outbreak.)

sudden start of war or violence
The moment when war or serious violence suddenly starts between groups or countries.
用法パターン：
the outbreak of [war/violence/hostilities]
よくある間違い：
Learners sometimes mix this sense with disease and say things like *"a war outbreaked"*. *Outbreak* here is still a noun; use *the war broke out* or *there was an outbreak of war*. Also, *outbreak* usually describes the start of something large and serious, not small fights or arguments between individuals.
類義語
eruption (Often used figuratively for sudden, intense violence or conflict; slightly more literary in this sense.)
|
flare-up (Suggests a short or sudden increase in conflict, sometimes less large-scale than a full outbreak of war.)
対義語
peace (A general state without war or violent conflict, which contrasts with the beginning of war.)
|
ceasefire (A formal stop to fighting, the opposite phase of the moment when fighting first begins.)

sudden burst of activity or emotion
A time when many people suddenly show the same strong feeling or action, like laughing or protesting.
用法パターン：
an outbreak of [emotion/activity]
よくある間違い：
Learners may confuse *outbreak* with *outburst* and say *"an outbreak of anger from him"* when *"an outburst of anger from him"* is more natural for one person. *Outbreak* usually involves many people or a group situation. Also, this sense is less common than the disease or war senses, and some learners overuse it where a simpler word like *sudden* or *burst* would be more natural.
類義語
outburst (Often refers to a sudden strong emotion from one person, whereas *outbreak* usually involves many people or a group event.)
|
eruption (More figurative and a bit more literary; suggests something sudden and forceful, similar in feeling but less common in everyday speech.)
対義語
calm (Describes a quiet, peaceful state without sudden strong activity or emotion, the opposite of an outbreak.)
|
lull (A period of quiet or reduced activity, contrasting with a sudden increase in activity during an outbreak.)
