Which statement about malaria prevention is true?

• A. Vaccines prevent malaria.
• B. Antibiotics prevent malaria.
• C. Malaria cannot be prevented.
• D. Vector control and nets/repellents prevent malaria.

Answer: (D)

Malaria prevention centers on stopping contact with the mosquitoes that transmit the parasite and reducing their numbers. Using nets, especially insecticide-treated nets, creates a barrier between people and biting mosquitoes, particularly at night when they are most active. Personal protection like repellents adds another layer of defense against bites. At the community level, vector control measures such as eliminating standing water and indoor spraying reduce the mosquito population and the chances of transmission. While vaccines are being developed, they are not yet the standard preventive tool, and antibiotics don’t prevent malaria because it is caused by a parasite, not bacteria. Therefore, focusing on vector control and nets/repellents best captures the true preventive approach.
