Which one of the following statements is correct regarding Sexually Transmitted Diseases (STD) ?
- Haemophilia is one of the STD
- The chances of a 5-year-old boy contracting an STD are very little
- A person may contract syphilis by sharing milk with one already suffering from the disease
- Genital herpes and sickle-cell anaemia are both STD
Answer
(2) The chances of a 5-year-old boy contracting an STD are very little
Solution
As per NCERT, STDs (STIs) are transmitted through sexual intercourse; some (hepatitis-B, HIV) also through sharing of injection needles, transfusion of infected blood or from infected mother to foetus. Persons in the age group of 15–24 years are most vulnerable.
⇒ A 5-year-old boy is not sexually active, so his chances of contracting an STD are very little. Statement (2) is correct.
⇒ Haemophilia and sickle-cell anaemia are genetic (Mendelian) disorders, not STDs; statements (1) and (4) are wrong.
⇒ Syphilis is not transmitted by sharing milk or food; statement (3) is wrong.
