Who determines the effectiveness of aerial spraying?

• A. Aerospace Medicine Council
• B. Bioenvironmental Engineering
• C. Base Civil Engineering
• D. Public Health

Answer: (D)

The main idea is who evaluates whether a vector-control operation actually reduces disease risk and mosquito populations. Public Health is responsible for determining effectiveness because they oversee disease surveillance, entomological monitoring, and health outcomes to see if the spraying achieved its goals. They collect data on mosquito density and infection rates, track reported human cases of vector-borne diseases, and assess program performance to decide if the spray worked or if adjustments are needed. Bioenvironmental Engineering contributes by handling safety, environmental impact, and operational logistics, but the formal judgment of effectiveness—whether health risk has been reduced—falls under Public Health.
