Main Answer:
HIV is mainly transmitted through drug use and shared needles, facilitating direct bloodborne transmission and increasing infection risk. c. drug use and sharing of needles.
Therefore, the correct answer is c. drug use and sharing of needles.
Step-by-step explanation:
HIV is most commonly spread through drug use and the sharing of needles. This is because the virus is present in blood, and when individuals share needles for injecting drugs, they can inadvertently transmit the virus from one person to another. The exchange of contaminated needles facilitates the direct entry of the virus into the bloodstream, making drug use a significant mode of HIV transmission.
Additionally, engaging in unprotected sexual activities, particularly heterosexual or homosexual contact, can also transmit HIV. However, the main contributor to the spread of HIV globally is through drug use and needle sharing. The sharing of needles not only poses a risk for the transmission of HIV but also increases the likelihood of other bloodborne infections. This makes it crucial to address substance abuse issues and implement harm reduction strategies to curb the spread of HIV in high-risk populations.
Understanding the primary modes of HIV transmission is essential for designing effective public health interventions and awareness campaigns. By focusing on preventive measures such as education on safe drug use practices, access to clean needles, and support for individuals struggling with substance abuse, we can work towards reducing the incidence of HIV infections. It is vital to prioritize comprehensive approaches that address the root causes of HIV transmission, fostering a healthier and more informed society.
Therefore, the correct answer is c. drug use and sharing of needles.
