Which country was highlighted as promotional usage of DDT as a disease-control measure?

• A. India
• B. Sri Lanka
• C. Thailand
• D. Pakistan

Answer: (B)

Promoting DDT as a disease-control measure highlights the historical push to showcase how effectively DDT could reduce disease, especially malaria, through widespread spraying. Sri Lanka became the classic example: in the mid-20th century, a nationwide indoor residual spraying program using DDT led to a dramatic drop in malaria cases, and the country’s results were widely cited to demonstrate the potential of chemical vector control. This strong, widely publicized success is why Sri Lanka is the country highlighted in discussions of promotional DDT use. Other countries did use DDT as well, but Sri Lanka’s case is the well-known promotional icon.
