To avoid the stigma of エイズ, Japanese speakers may use the phrase HIV陽性 'HIV yōsei' meaning 'HIV positive'. This shift focuses on the viral status rather than the syndrome itself.
In Japanese media, エイズ is often paired with the word 啓発 'keihatsu', meaning 'awareness' or 'enlightenment'. This creates a specific bureaucratic term エイズ啓発 for public health campaigns.
In Japanese, the word for 'acquired' in the full term for エイズ is 後天性 'kōtensei', which literally means 'acquired after birth'.
