Dengue fever risk increases due to pools of stagnant floodwater.
Is it true that Dengue fever risk increases due to pools of stagnant floodwater?
Yes. Multiple systematic reviews and epidemiological studies confirm that standing water from floods and inadequate drainage creates prime breeding sites for mosquitoes, thereby increasing the risk of dengue fever transmission.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The retrieved literature contains strong evidence from systematic reviews and modeling studies showing a clear link between flooding, stagnant water, and increased incidence of vector-borne diseases like dengue. There is no evidence refuting this well-established epidemiological relationship.
