一般情況下，將「contagion」視為不可數名詞使用；僅在特指具體的傳染病種類時，才使用其可數複數形式「contagions」。
contagion vs infection
「contagion」強調疾病透過接觸或媒介「傳染」的過程與特性；「infection」則側重病原體侵入人體後引發的「感染」狀態。
contagion vs epidemic
「contagion」指疾病傳播的機制或行為本身；「epidemic」指疾病在特定區域、時間內發病率顯著高於平常的「流行」狀態。
contagion vs transmission
「contagion」常帶有疾病「可傳染」的性質或引發的擴散後果；「transmission」是較中性的「傳播」行為描述，可用於疾病、資訊、能量等。
在對話中，人們有時會用「contagion」來引述或轉述他人的觀點，特別是關於社會現象或情緒傳播的討論。 EN: He kept talking about the "contagion of fear" spreading online. 翻譯: 他一直在談論網路上蔓延的「恐懼傳染」。
EN:I read an article that described the trend as a "social contagion."

EN:Her laughter is a contagion; you just can't help but join in.

×The contagion of laughter spread quickly in the room.
✓The laughter was contagious and spread quickly in the room.
While 'contagion' can be used metaphorically, it is more formal and often carries a negative connotation (like disease or harmful influence). For positive things like laughter, 'contagious' (adjective) is more natural and common.
×He got a contagion from his classmate.
✓He caught an infection from his classmate. / He was exposed to a contagion.
'Contagion' refers to the *disease itself* or the *process* of spreading, not the state of being sick. You 'catch' a disease or infection. You can 'be exposed to' a contagion or 'spread' a contagion.
×Social media can cause emotional contagions.
✓Social media can cause emotional contagion.
When used in an abstract, uncountable sense to describe a general process or phenomenon (like the spread of emotions, ideas, or financial panic), 'contagion' is often uncountable. The plural 'contagions' is less common and typically refers to multiple distinct diseases or specific instances.
×We need to stop the contagion of the virus.
✓We need to stop the spread of the virus.
This is a redundancy error. 'Contagion' already implies the *act or process* of spreading a disease. 'The spread of the virus' is clearer and more common. 'Stop the contagion' is acceptable but less precise than 'stop the spread'.
×It's a very contagion situation.
✓It's a very contagious situation. / There is a high risk of contagion.
'Contagion' is a noun. To describe something that can spread easily, use the adjective 'contagious'. The noun 'contagion' names the thing/process that spreads.
