Singapore's authorities implement integrated vector management:

NEA conducts surveillance, including Gravitraps for mosquito detection and breeding site removal.

MOH issues public alerts, educates on prevention, and manages healthcare responses.

Community programs encourage resident participation in cleanup campaigns, supported by fines for non-compliance with mosquito control regulations to sustain low incidence.

Authorities like meteorological agencies issue alerts through emergency broadcasts.

Responses include evacuation orders, shelter-in-place advice, and distribution of iodine tablets to block radioactive absorption.

Long-term monitoring ensures public safety.
