Summary of Dengue Control Efforts Adopted by the Singaporean Government

Initiative	Aim
Mosquito control
National Dengue Prevention Campaign5	Launched in March by the National Environment Agency (NEA), ahead of the usual May launch coinciding with the start of “dengue season”, to mobilise the nation to be conscientious in housekeeping, remove stagnant water, and deprive Aedes mosquitoes of breeding habitats.
NEA Wolbachia Mosquito factory in Ang Mo Kio, Singapore5	NEA produces up to two million Wolbachia mosquitoes weekly for release and aims to breed about five million weekly. Male mosquitoes infected with Wolbachia bacteria are released to mate so resultant eggs cannot produce offspring, making the wild population crash. Multi-year data from pilot sites in Tampines and Yishun suggest the approach successfully reduced mosquito populations there.
Dengue vaccine
Dengvaxia23	Singapore’s Health Sciences Authority states this vaccine is approved for use only for Singaporeans aged 12–45 who have already been infected with at least 1 dengue strain and requires three doses administered over 12 months.
Legislative measures
Infectious Diseases Act (IDA); Control of Vectors and Pesticides Act (CVPA); Environmental Public Health Act (EPHA)	These acts prescribe significant penalties for anyone failing to comply with the law. IDA deals with notification, investigation and treatment of dengue; CVPA deals with vector control; and EPHA deals with environmental sanitation and other environmental public health issues.
