(a) List two sexually transmitted diseases in each of the following cases:
(i) Bacterial infections
(ii) Viral infections
(b) How may the spread of such diseases be prevented?
(a) Sexually Transmitted Diseases (STDs):
- (i) Bacterial infections: Gonorrhoea, Syphilis.
- (ii) Viral infections: Warts, HIV-AIDS.
(b) Prevention of spread:
The spread of sexually transmitted diseases can be prevented by using mechanical barrier methods, such as condoms for the penis during sexual intercourse. These barriers prevent the transmission of bodily fluids and pathogens from one partner to another.
Marking Scheme
- 1Listing two bacterial infections (Gonorrhoea, Syphilis). (1 mark)
- 2Listing two viral infections (Warts, HIV-AIDS). (1 mark)
- 3Explaining the use of barrier methods (condoms) to prevent transmission. (1 mark)
Hint
Think of diseases like Syphilis and AIDS, and remember how physical barriers block fluid transmission.
Quick Oral Answer
Bacterial STDs include Gonorrhoea and Syphilis, while viral STDs include Warts and HIV-AIDS. They can be prevented by using barrier methods like condoms during intercourse.
Analysis & Explanation
Sexually transmitted diseases (STDs) are infections transmitted through sexual contact. They can be caused by bacteria or viruses. Bacterial STDs like Gonorrhoea and Syphilis can often be treated with antibiotics, whereas viral STDs like HIV-AIDS and Warts are more difficult to cure. Prevention relies heavily on barrier methods (like condoms) because they physically block the passage of pathogens, unlike chemical or hormonal contraceptives (like oral pills) which only prevent pregnancy but do not protect against STDs.
Common Mistakes
- 1Interchanging bacterial and viral pathogens (e.g., listing AIDS as bacterial).
- 2Suggesting chemical contraceptives (like copper-T or oral pills) as methods to prevent STDs, which only prevent pregnancy and offer no protection against infections.
Interesting Facts
Condoms are the only contraceptive method that provides dual protection: they prevent unwanted pregnancies as well as the transmission of STDs.
