Common Questions About AIDS in Spanish
- Why do the letters in SIDA differ from AIDS?
- Spanish grammar places adjectives after nouns, so 'Acquired Immune Deficiency Syndrome' becomes 'Síndrome de Inmunodeficiencia Adquirida.' The acronym SIDA reflects this natural Spanish word order rather than transliterating the English letters.
- Is SIDA masculine or feminine in Spanish?
- SIDA is grammatically masculine because 'síndrome,' the core noun in the full name, is a masculine word. Therefore, you always say 'el SIDA' with the masculine definite article, even though the acronym ends in the letter A.
- How do you distinguish between HIV and AIDS in Spanish?
- HIV is called 'VIH' (Virus de Inmunodeficiencia Humana) in Spanish, while AIDS is 'SIDA.' Medical professionals emphasize that being VIH-positivo does not necessarily mean a person has developed SIDA, as the virus and the syndrome are clinically distinct.
