Write two examples each of sexually transmitted diseases caused by (i) virus, (ii) bacteria. Explain how the transmission of such diseases be prevented?
Write two examples each of sexually transmitted diseases caused by (i) virus, (ii) bacteria. Explain how the transmission of such diseases be prevented?
Official answer
(i) Sexually Transmitted Diseases (STDs) caused by Virus:
- HIV-AIDS
- Genital Warts
(ii) Sexually Transmitted Diseases (STDs) caused by Bacteria:
- Gonorrhoea
- Syphilis
Prevention of Transmission:
The transmission of sexually transmitted diseases can be prevented by using mechanical barriers such as a condom during sexual intercourse. Condoms prevent the direct contact of body fluids and genital surfaces between partners, thereby blocking the transmission of disease-causing pathogens (viruses and bacteria).
Marking scheme
- 1.Two examples of viral STDs (0.5 mark each): 1 Mark
- 2.Two examples of bacterial STDs (0.5 mark each): 1 Mark
- 3.Explanation of prevention using mechanical barriers like condoms: 1 Mark
Hint
Recall the bacterial and viral infections of the reproductive tract mentioned in the reproductive health section. Think of mechanical barriers used for safe sex.
Quick oral answer
Bacterial STDs include Gonorrhoea and Syphilis, while viral STDs include HIV-AIDS and Warts. They can be prevented by using condoms, which act as a mechanical barrier.
Common mistakes
- 1.Interchanging bacterial and viral STDs (e.g., writing Gonorrhoea as viral).
- 2.Suggesting chemical methods (like oral pills) as a way to prevent STDs, whereas pills only prevent pregnancy, not STDs.
Analysis and explanation
STDs are infections transmitted through sexual contact. Pathogens can be bacterial (like Neisseria gonorrhoeae and Treponema pallidum) or viral (like Human Immunodeficiency Virus and Human Papillomavirus). Mechanical barriers like condoms are highly effective because they physically block the exchange of infectious fluids.
Interesting facts
While hormonal contraceptives (like oral pills) are highly effective at preventing pregnancy, they offer absolutely no protection against sexually transmitted infections (STIs). Only barrier methods like condoms do.
