Which of the steps given above the correct?

Options

A. I and III
B. III and IV
C. II, III and IV
D. I, II, III and IV

Answer

To answer the question regarding the steps taken by the World Health Organization (WHO) to prevent the spread of HIV infection, we can analyze each of the provided options:

1. **Ensuring use of disposable needles and syringes**: This step is crucial in preventing the transmission of HIV, especially among intravenous drug users. By using disposable needles, the risk of sharing needles, which can spread the virus, is significantly reduced. Therefore, this step is correct.

2. **Free distribution of condoms**: Condoms are an effective barrier method that helps prevent the transmission of sexually transmitted diseases (STDs), including HIV. By distributing condoms for free, WHO promotes safer sexual practices, which is essential in controlling the spread of HIV. This step is also correct.

3. **Advocating safe sex**: Promoting safe sex practices, such as using condoms and reducing the number of sexual partners, is vital in preventing HIV transmission. This advocacy helps educate individuals about the risks associated with unprotected sex. Hence, this step is correct as well.

4. **Controlling drug abuse**: Drug abuse can lead to risky behaviors, including sharing needles and engaging in unprotected sex. By controlling drug abuse, WHO aims to reduce the incidence of HIV infections associated with these behaviors. Therefore, this step is also correct.

In conclusion, all the steps mentioned (I, II, III, and IV) are correct measures taken by the WHO to prevent the spread of HIV infection.

**Final Answer**: All the steps (I, II, III, IV) are correct.
