Question

Which of the following is not a sexually transmitted disease (STD)?

• A. Hepatitis B
• B. Syphilis
• C. Gonorrhea
• D. Ascariasis

Hint:

If a disease is caused by a parasite like a roundworm (e.g., Ascariasis), it's likely transmitted via poor hygiene, not sexual activity.

Answer 1

The Correct Option is D

Ascariasis is a parasitic infection caused by the roundworm Ascaris lumbricoides. It is transmitted via contaminated food or water (fecal-oral route), not through sexual contact. Explanation of other options:

• (a) Hepatitis B is a viral infection that can be transmitted sexually — it is considered an STD.
• (b) Syphilis is a bacterial STD caused by Treponema pallidum.
• (c) Gonorrhea is a common STD caused by the bacterium Neisseria gonorrhoeae.
