常見錯誤

❌The patient is infected the disease.
✅The patient is infected with the disease.
💡When specifying the cause, 'infected' must be followed by 'with', not used as a transitive verb.
❌I feel infected today.
✅I feel sick today.
💡'Infected' is a medical term for a confirmed germ invasion; do not use it for general, vague feelings of being unwell.

用法筆記

Used only for computers, files, networks, and software. The most complete phrasing includes what the device is infected with: 'infected with a virus' or 'infected by malware.' Saying 'infected' alone can sound incomplete in this sense.

常見錯誤

❌My phone is infected.
✅My phone has a virus.' or 'My phone is infected with malware.
💡Saying 'infected' alone about a device sounds incomplete; specify what type of harmful software it contains.
