The correct answer is
Chancroid is an STI caused by bacteria. It occurs in the U.S. in outbreaks from time
to time, but it is common in sub-Saharan Africa. Like genital herpes and syphilis,
the first symptom of chancroid is an open sore on the genitals. Lymph nodes in the
groin swell and become painful. Scabies is a skin infection with a tiny mite. It is
fairly common and highly contagious. It can be spread through sexual contact. But
it also can be passed on by nonsexual contact with skin, infested sheets, towels,
and furniture. Scabies causes intense itching, especially at night. Small red bumps
or lines appear on the body where the female scabies mite has burrowed into the skin
to lay her eggs. Molluscum contagiosum is a common viral infection that most often
affects young children, who pass it to one another through saliva. In adults, the
virus is passed on sexually. Symptoms are bumps on the chest, genitals, lower abdomen,
buttocks, or inner thighs. Human T-cell lymphotropic virus (HTLV) can be passed from
one person to another not only through sexual contact but also through blood. This
is a rare disease in the U.S. It is mostly found among IV drug users and people who
have genital ulcers or a history of syphilis. HIV is also usually passed sexually.
