Dengue cases rising sharply, NEA calls for ‘urgent collective community effort’ to fight rise


SINGAPORE – Dengue cases are rising sharply, with 264 cases recorded within the week ending March 5, mentioned the National Environment Agency on Thursday (March 10).

This is a rise of 65 cases in contrast to the earlier week.

There have been greater than 1,500 reported dengue cases this 12 months as at March 5, with the weekly variety of cases climbing steadily up to now eight weeks, mentioned NEA in a media launch.

“A contributing factor and key concern is the high Aedes aegypti mosquito population detected in the community, which has increased by about 9 per cent in January 2022 compared to in the same period last year,” mentioned NEA.

The feminine Aedes aegypti mosquito is the first vector of dengue.

“If left unchecked, the current high Aedes aegypti mosquito population – together with circulation of the previously uncommon dengue virus serotype 3 (DENV-3) and sizeable proportion of people still staying in and working from home – may lead to a surge in dengue cases in the coming months,” added NEA.

The company referred to as for “urgent collective community effort” to drastically cut back mosquito breeding habitats and decelerate the rise within the variety of cases.

“NEA therefore urges members of the public and other stakeholders to stay vigilant and not let their guard down, as dengue remains a serious public health threat,” it added.

New purple alert banners shall be deployed in areas with persistently excessive Aedes aegypti mosquito inhabitants within the coming weeks.

Such areas have greater mosquito populations in contrast to others for durations of three months or extra, in accordance to NEA’s monitoring system.

Said NEA: “These areas kind a subset of places with greater Aedes aegypti mosquito inhabitants, which NEA presently updates month-to-month on its web site.

“The intent is to alert residents, community partners, and key stakeholders at such areas to take preventive measures against mosquito breeding, in order to reduce the risk of dengue.”

These new purple alert banners are as well as to NEA’s present Dengue Community Alert System, which incorporates the show of colour-coded banners – in pink, yellow or inexperienced – to inform residents and members of the general public concerning the dengue state of affairs at their estates.

NEA suggested residents residing in areas with the purple banners to practise the Mozzie Wipeout “B-L-O-C-K” steps at the very least as soon as every week to take away stagnant water.

BLOCK is an acronym for breaking apart hardened soil; lifting and emptying flowerpot platters; overturning pails and wiping their rims; altering water in vases; and retaining roof gutters clear and putting BTI insecticide in them.

BTI pesticides faucet micro organism to produce toxins which might kill mosquitoes.

As at 5pm on Thursday, there have been 12 pink alerts, or high-risk areas with greater than 10 dengue cases; and 45 yellow alerts, or high-risk areas with fewer than 10 dengue cases, recognized on a dengue cluster monitoring map on NEA’s web site.

The largest pink alert cluster is in a locality off Dunearn Road, bounded by Hua Guan Avenue and Rifle Range Road.

Other pink alert clusters are in areas off Jalan Jurong Kechil, off Holland Road and Woodlands Drive 17.

“Our dengue prevention efforts are not only focused on dengue cluster areas, but include non-dengue cluster areas that have higher Aedes aegypti mosquito populations,” mentioned Mr Chew Ming Fai, NEA’s deputy chief govt.

“Taking a pre-emptive approach in heightening dengue awareness and mobilisation of the community for dengue prevention efforts is key to our vector control strategy.”
