Which term denotes a disease transmitted through sexual contact?

• A. Sexually Transmitted Disease
• B. Urinary frequency
• C. Polyuria
• D. Perineum

Answer: (A)

The concept being tested is the mode of transmission. A disease that is spread specifically through sexual contact is described with the term sexually transmitted disease. This label groups infections that are transmitted via intimate sexual activities, including vaginal, anal, or oral sex, through infected secretions or mucous membranes. Some infections fall under this umbrella with varying symptoms—some people may have noticeable signs, while others may be asymptomatic, yet still capable of transmission. Examples include infections like gonorrhea, chlamydia, syphilis, HIV, and HPV. The other options don’t fit because urinary frequency and polyuria are signs or symptoms related to urinary tract or metabolic issues, not diseases by transmission route, and the perineum is an anatomical region, not a disease term.
