Sexually Transmitted Infections Overview — NEET Biology
✅ Asked in NEET 2020Select the option including all sexually transmitted diseases. (NEET 2020)
Select the option including all sexually transmitted diseases. (NEET 2020)
Match the following sexually transmitted diseases (Column I) with their causative agents (Column II): (NEET 2017)
Which of the following is not a sexually transmitted disease?
Which of the following viruses is not transferred through semen of an infected male?
Answer & NCERT explanation
Correct answer: C — Gonorrhoea, Syphilis, Genital Herpes
All three - Gonorrhoea, Syphilis, and Genital Herpes are sexually transmitted diseases. Gonorrhoea is caused by Neisseria gonorrhoeae bacteria, Syphilis by Treponema pallidum bacteria, and Genital Herpes by Herpes Simplex Virus. Other options include non-STDs like Malaria (vector-borne), Filaria (vector-borne), and Cancer (not infectious).

Infections or diseases which are transmitted through sexual intercourse are collectively called sexually transmitted infections (STI) or venereal diseases (VD) or reproductive tract infections (RTI). Gonorrhoea, syphilis, genital herpes, chlamydiasis, genital warts, trichomoniasis, hepatitis-B and of course, the most discussed infection in the recent years, HIV leading to AIDS are some of the common STIs. Among these, HIV infection is most dangerous and is discussed in detail in Chapter 7.
NTA tests students' knowledge of common STIs like gonorrhoea, syphilis, genital herpes, chlamydiasis, and HIV/AIDS. The core concept is identifying disease types and transmission routes. Students often confuse STI causes (bacterial vs viral vs parasitic) or mix up their symptoms. Remember: gonorrhoea and syphilis are bacterial; herpes is viral; trichomoniasis is parasitic; HIV is the most dangerous. When answering, focus on distinguishing these infections by causative agent and whether they're curable (bacterial antibiotics) or manageable (viral antivirals). This remains testable because reproductive health is a high-priority NEET topic with clinical relevance.
