infectious
When talking about diseases, 'infectious' describes how a germ can move from one person to another. It is often used with words like 'highly' or 'extremely' to show how fast it spreads. When talking about emotions—like laughter or excitement—it is used as a metaphor. It means the feeling is so strong that other people around you start to feel it too.

Eleanor is using 'infectious' in its medical sense to express concern about contagion. Chloe responds with casual internet slang ('lol') and the phrasal verb 'chill out', reflecting the generational gap in their communication styles.
