The English medical term "hepatitis C" is spelled the same in Spanish. When saying the term in Spanish, the speaker applies the silent "h" rule. Unlike its English pronunciation, all the vowel sounds are short. The "C" is pronounced in Spanish as an English pronunciation of "seh."
Hepatitis C is a feminine noun in Spanish, meaning the article "la" usually precedes it. The hepatitis C virus translates to Spanish as "el virus de la hepatitis C"; therefore, the English abbreviation HCV is "VHC" in Spanish. Enzyme immunoessays, the blood test done to detect a body's antibodies against hepatitis C, translates to Spanish as "enzimoinmunoanálisis."
