SINGAPORE - The majority of the 72 clusters are in the central and eastern parts of the country - traditionally the worst-hit areas for dengue.

In the week ending June 28, there were 676 reported cases of dengue. This is a significant increase in cases from the previous week, the National Environment Agency (NEA) said on its dengue website.
So far, close to 9,000 people have been infected this year.
The agency added that there may be a further rise in dengue incidence as the warmer weather over the next two to three months shortens the breeding and maturation cycles of the Aedes mosquitoes, as well as the incubation periods for the dengue virus.
"The best way to mitigate the higher transmission is to continue efforts to reduce the mosquito population," NEA said.
NEA and its Inter-Agency Dengue Task Force partners, as well as Town Councils, are continuing in its efforts to check for and remove potential mosquito breeding habitats.
"As community support is critical in stopping dengue transmission, we strongly encourage everyone to do the 5-Step Mozzie Wipout and join in the collective effort to fight dengue," NEA said.
