Passage Summary: Usually, more rain means more mosquitoes and more sickness, but in swamps, the sickness actually gets worse when it's dry.

Reasoning: Mosquitoes require water to breed, yet in wetland habitats, disease outbreaks actually worsen during periods of drought rather than wet weather.

Analysis: To resolve this paradox, we need a reason why a drought would actually help spread a mosquito-borne disease in a wetland. In a typical environment, drought kills mosquitoes by drying up their water, but in a wetland, a drought might just shrink the water into small, stagnant pools. This could concentrate mosquitoes and their hosts (like birds) into the same small areas, making it much easier for the disease to jump between them. Look for an answer that explains how dry conditions specifically facilitate transmission in these water-rich areas.
