Singapore dengue cases surpass 2023 total with five months to go in the year
The agency’s latest update (as of Jul 22) showed that there are 70 active dengue clusters in Singapore. Ten are considered red-alert clusters, which indicate high-risk areas with 10 or more cases each.
One such area is in Jurong West (Avenue 1, Avenue 2, Street 42) with 103 cases since the start of the cluster. NEA also noted persistent transmission at the 410-case Gangsa Road cluster and 47-case Benoi Road cluster.
There are four dengue virus serotypes circulating in Singapore. Dengue virus serotype 2 (DENV-2) has been predominant since September 2023, with prior periodic dominance of DENV-1 and DENV-3 in 2023.
“Our population’s immunity to all four dengue virus serotypes remains low,” said NEA.
“The continued presence of all these dengue risk factors may lead to a surge in dengue cases in the coming months, if insufficient action is taken.
It added that there are nine isolated Zika cases reported so far in 2024, with no clusters to date. Similar to dengue, Zika is a virus infection that is spread by the Aedes mosquito.
