IPA: /ˌʌnɪnˈfɛktɪd/
KK: /ʌnɪnˈfɛktɪd/
Not affected by a disease or infection.
The doctor confirmed that the patient was uninfected after the tests were completed.
Uninfected → It is formed from "un-" (meaning not) and "infected" (from Latin "infectus", meaning tainted or contaminated). The word "uninfected" means not tainted or contaminated by infection.
Think of 'not' ('un-') being added to 'infected', which means tainted. This helps you remember that 'uninfected' refers to something that is not tainted or contaminated.
