Which measure helps mitigate vector breeding after floods?

• A. Drain standing water and improve drainage
• B. Build more shelters
• C. Plant trees around shelters
• D. Increase pesticide use without monitoring

Answer: (A)

Controlling vector breeding after floods is all about removing the places where they can lay eggs and develop. Floods leave many areas with pools of standing water, which are perfect breeding sites for mosquitoes and other vectors. Draining this standing water and improving drainage stops these habitats from forming or persisting, directly reducing vector numbers and the risk of vector-borne diseases in affected communities. Other options don’t tackle the root issue. Building more shelters doesn’t reduce the standing water that vectors need. Planting trees around shelters changes some local conditions but doesn’t remove breeding sites. Increasing pesticide use without monitoring can give only short-term relief and risks resistance and environmental harm, making it unsustainable as a sole strategy.
