The National Environment Agency (NEA) warns Singaporeans to take immediate action in combating dengue after seeing a sharp increase in recently reported cases.

Over 6,2000 dengue cases were reported on Tuesday (Sep 5), adding on to the surge in Dengue virus serotype 1 (DENV-1) cases from the past two months. With more large and persistent dengue clusters appearing across Singapore, the risk of cases surging is high. 

This increase in DENV-1 cases surpasses that of the previously dominant Dengue virus serotype 3 (DENV-3), of which the former overtook in monthly proportion since July. NEA notes that this “rise in proportion of a previously less prevalent Dengue virus serotype” is concerning, as such situations are commonly linked with a surge in dengue cases months later.

Currently, there are 48 active dengue clusters nationwide, with 13 of which being large clusters holding 10 or more cases. Among these 13 large clusters, two – Science Park Drive and Lentor Loop – have fast dengue transmission rates, while those in Lorong 1 and Lorong 2 Toa Payoh have the most persistent dengue transmissions.

Other large dengue clusters are located at Lorong 1A Toa Payoh, Lorong 3 Toa Payoh, Toa Payoh North, Thomson Lane, Angklong Lane, Eng Kong Road, Jalan Pacheli, Buangkok Green and Tampines Street 22.

NEA reported that 68 per cent of Aedes mosquito breeding sites at dengue cluster areas were found in homes. About 29 per cent are located at public areas, one per cent at construction sites, and two per cent at other premises.

In order to tackle the surge in dengue cases, NEA urges Singaporeans to carry out the S-A-W actions. Individuals should spray insecticide in dark corners around the house, apply insect repellent regularly, and wear long-sleeved tops and long pants. 

Singaporeans should also regularly practice the Mozzie Wipeout.

NEA will continue working with Town Councils, premises operators and the Inter-Agency Dengue Task Force to curb transmissions in dengue clusters. This includes actions like spraying insecticide, larviciding and fogging residential premises and common areas.

In the meantime, individuals diagnosed with or suspected of being infected with dengue are advised to avoid further mosquito bites and prevent transmitting the virus to others. 

Residents living in cluster areas should also cooperate with NEA officers when they conduct checks and indoor misting, so as to prevent mosquito breeding and the spread of dengue at a faster rate.
