What impact does climate change have on disease vectors?

• A. It increases their resistance to treatments
• B. It alters their habitats and affects transmission
• C. It makes them less common in urban areas
• D. It has no impact on their populations

Answer: (B)

Climate change significantly alters the habitats of disease vectors, such as mosquitoes and ticks, thereby influencing their breeding, survival, and distribution. As global temperatures rise, these vectors may flourish in previously unsuitable areas, expanding their geographic range and potentially leading to increased transmission of diseases. Changes in precipitation patterns can also create more favorable environments for breeding, such as puddles and stagnant water, which are ideal for mosquito larvae. By modifying ecosystems and weather patterns, climate change can lead to a higher incidence of vector-borne diseases, impacting public health on a broader scale.
