infection
This word can be used as both a countable and an uncountable noun. When referring to the general process of spreading germs, it is often uncountable. When referring to a specific illness in a person (like 'a throat infection'), it is used as a countable noun. In casual conversation, people sometimes use 'infection' loosely to describe any irritation or redness on the skin, even if a doctor has not yet confirmed the presence of germs.

Eleanor uses all caps due to her technological illiteracy and index-finger typing style. Chloe uses 'yikes' as a casual expression of mild alarm/disgust and the phrase 'deal with' as a common phrasal verb meaning to handle or cope with a difficult situation.
