Healthy Populations Exam 3 Practice

When both partners aren’t treated for an STI like trichomoniasis, the situation often becomes a cycle of reinfection between them, sometimes called a ping-pong effect. Trichomoniasis is spread through sexual contact, so if one person is treated but the other isn’t, they can pass the parasite back to each other during intercourse after treatment, leading to ongoing infection in both. Treating both partners at the same time breaks this cycle, reducing the chance of reinfection and helping both clear the infection effectively. The other statements aren’t correct because an untreated infection doesn’t disappear on its own, the infection can be transmitted to a partner, and typically both partners need treatment to stop the spread.
