have / be diagnosed with AIDS

用法筆記

Almost always written in capitals (AIDS) because it is an initialism for Acquired Immunodeficiency Syndrome; treated as an uncountable noun, so used without 'a' or 'an' and with singular verbs. Distinguish from HIV: HIV is the virus, AIDS is the late stage of illness it can cause.

常見錯誤

✅He has AIDS.
💡AIDS is uncountable; never use 'a / an' before it.
❌She caught AIDS from sharing a cup.
✅She was infected with HIV through unprotected sex.
💡AIDS itself is not 'caught'; HIV is the virus that is transmitted, mainly via blood or sexual contact, not through everyday social contact.
