Weekly new dengue cases hit an all-time high of 1,570 as of May 28

Another surge in dengue case numbers was recorded in the past week, with 1,570 new dengue cases reported in the week ending May 28. 

This is the highest number of cases reported in a single week in 2022, surpassing the previous record in the week ending May 14. 

The total number of dengue cases recorded this year as of May 28 stands at 11,674, more than twice the 5,258 cases recorded in the entire year of 2021. 

There were also 398 active dengue clusters as of May 30. Among these, 103 dengue clusters have been put on red alert as they contain 10 or more cases. 

The Lorong Kismis and Cheng Soon Crescent area in Bukit Timah remains the largest cluster with 455 cases in total, up from 408 last week.

A previously uncommon dengue serotype DENV-3 has also been detected in more than half of the clusters with red alerts. 

This will lead to “a further surge in dengue cases in the coming months,” said the National Environment Agency (NEA) in an update on May 30.

“Most mosquito breeding continues to be found in homes,” it added.

Residents are therefore advised to “use mosquito repellent regularly”, especially if they are living in areas with dengue clusters. Repellents with the active ingredients DEET, picaridin or IR3535 are recommended as they are more effective in repelling mosquitoes. 

Residents should also continue to carry out the “B-L-O-C-K” and “SAW” techniques to prevent mosquitoes from breeding and protect themselves from dengue, said the NEA.
