Klang district has recorded an average of 83 dengue cases per week since Jan 1, indicating steady transmission across the city, according to health officials.
Klang District Health Department (PKD) officer Dr Noriah Ismail said this weekly average over the 19-week period made the disease a continuing public health priority.
Speaking at a “gotong-royong for a dengue-free community” event at Prima Bayu Apartments in Bayu Tinggi, she said high- density residential buildings presented distinct operational challenges for containment teams.
“Health inspectors are able to manage active clusters more effectively in landed neighbourhoods compared to strata properties,” she said.
Dr Noriah added that the close proximity in apartment living fed the prevalence of the disease.
PKD reported two deaths for the period ending May 17, compared to one during the corresponding period last year.
The authorities noted that there was an overall decline in total infections, which fell to 1,583 cases from 2,050 recorded during the same period last year.
Klang Royal City Council (MBDK) Health Department director Azmi Muji said the district recorded 4,207 cases across the whole of 2025.
He said Prima Bayu Apart-ments remained a recurrent focus for health monitoring, having registered 23 cases in 2023, 56 in 2024 and 25 last year.
He said MBDK and PKD continue to run targeted prevention operations throughout the district to clear breeding grounds.
Commenting on the gotong- royong, which included dissemination of information on Aedes mosquito and the prevention measures, MBDK Environmental Health assistant officer Rasyidah Ain Mohamad Soib said there was good response from residents.
“Search-and-destroy activities to eliminate dengue larvae were also carried out during the event,” she said.
