Explanation:

Question 16

HIV is transmitted through body fluids like blood. Sharing needles/syringes can transfer blood with HIV. PrEP (Pre - Exposure Prophylaxis) is for prevention. HIV is not transmitted via hairbrushes (no relevant body fluid transfer). A single sexual partner (if low - risk) is less risky than multiple partners.

Chancroid is caused by Hemophilus ducreyi. Genital warts are due to HPV. Lymphogranuloma inguinale has different causative agents (Chlamydia trachomatis). Syphilis is caused by Treponema pallidum.

"Pro - " means before (e.g., prologue - before the main part). "phylaxis" is related to guarding against. So "prophylaxis" is before/guard against.

Answer:

Sharing needles and syringes
