The National Environment Agency of Singapore (NEA) reports that the number of weekly dengue cases continues to rise sharply, even before the peak of the dengue season in June.

For the first 15 weeks of 2022, authorities are reporting 4,493 dengue fever cases, roughly double the total reported in the same period last year.

As of April 11, 2022, there were 145 active dengue clusters, with 33 dengue clusters with red color alert (i.e. 10 or more cases in the cluster). Dengue virus serotype 3 (DENV-3) was detected in 24 of 33 dengue clusters with a red color alert.

In February 2022, the Aedes aegypti the mosquito population (the main vector of dengue fever) remained high in parts of Singapore and was about 17% higher than the same period last year (February 2021). If nothing is done, the top Aedes Egyptian The mosquito population – together with the circulation of the previously rare DENV-3 and a proportion of people who are still staying and working from home – will lead to a further increase in dengue cases in the coming months.

Eradicating mosquito breeding habitats at source and spraying insecticides to control the adult mosquito population remain essential for dengue fever prevention. The NEA, in collaboration with the various agencies and other stakeholders represented in the Inter-Agency Dengue Task Force (IADTF), including city councils, has checked and cleared our public spaces and housing estates of potential breeding habitats. mosquitoes.

Residents, especially those residing in dengue cluster areas, are encouraged to perform the three dengue protective actions: “Spray, Apply, Wear” or ‘SEEN‘ brief:

Spray insecticide in the dark corners of the house
Aregularly apply insect repellent
Olong sleeve tops and long pants

The NEA advises members of the public to regularly use insect repellent to protect themselves from mosquito bites, particularly if they live in dengue risk areas. Repellents containing DEET (N,N-diethyl-m-toluamide), picaridin or IR3535 as the active ingredient, are the most effective in repelling mosquitoes.

People with symptoms suggestive of dengue should consult a doctor as soon as possible, in order to be diagnosed and taken care of accordingly. Early diagnosis can facilitate better case management, and people with dengue fever can also help prevent further transmission by applying repellent regularly, so mosquitoes don’t bite them and transmit the virus. Symptoms suggestive of dengue fever include:

  • Sudden onset of fever for two to seven days;
  • Severe headache with retro-orbital pain (behind the eye);
  • Joint and muscle pain
  • Rashes;
  • Nausea and vomiting;
  • Bleeding from the nose or gums;
  • Easy skin bruising.
