Prevention of AIDS — Prelims Strategy

Prelims Strategy

For NEET Prelims questions on AIDS prevention, a multi-pronged strategy is most effective. Firstly, thoroughly memorize the confirmed modes of HIV transmission (unprotected sex, sharing needles, mother-to-child, blood transfusions) and, equally important, the ways it is NOT transmitted (casual contact, insects, air, water).

This helps in quickly eliminating distractor options based on common myths. Secondly, understand the specific mechanisms and applications of key prevention methods: how condoms act as a barrier, how PrEP works proactively, how PEP works reactively, and how ART (Treatment as Prevention) reduces viral load to prevent transmission.

Pay close attention to the 'who, what, when, and why' for each intervention. For numerical or scenario-based questions (though less common for this topic), focus on identifying the core problem and matching it to the most appropriate prevention strategy.

Practice distinguishing between similar-sounding terms like PrEP and PEP. Always read the question carefully, especially looking for keywords like 'NOT', 'FALSE', 'most effective', or 'emergency intervention', as these dictate the precise answer required.

Conceptual clarity over superficial knowledge will be key to tackling tricky questions.
