SHAH ALAM, June 21 — The state recorded 15,549 dengue cases between January 1 and June 13, an increase of 29.9 per cent compared with 11,970 cases during the same period last year.
Harian Metro reported that state executive councillor for public health Jamaliah Jamaluddin said a shift toward the dominant DEN-3 subvariant has been identified as one of the factors potentially contributing to the rise.
The community’s lower immunity level towards the serotype may be among the reasons for the increase in infections.
“This change has the potential to contribute to the increase in cases because the community’s immunity level towards the serotype may be lower.
“However, the rise in dengue cases is also driven by a combination of factors, including weather conditions, the density of the Aedes mosquito population, and the effectiveness of mosquito breeding control measures on the ground,” she said.
Jamaliah was speaking after the launch of the 2026 Clean, Beautiful and Healthy Community Programme for the Hulu Kelang state constituency at the Ampang Jaya Municipal Council (MPAJ) Multipurpose Hall today.
She added that 1,242 dengue cases were reported during Epidemiological Week 23, covering the period from June 7 to June 13, representing an increase of 28.3 per cent compared with 968 cases recorded the previous week.
During the same period, Selangor recorded 15 dengue-related deaths, with a case fatality rate (CFR) of 0.09 per cent, compared with four deaths and a CFR of 0.03 per cent during the corresponding period last year.
Meanwhile, MPAJ Deputy President Hasrolnizam Shaari said 748 dengue cases were recorded in Ampang Jaya between January 1 and June 15.
The council also recorded 13 localities with controlled dengue outbreaks in the district, including Taman Keramat, Kampung Melayu Ampang, Taman Melawati, Taman Sri Raya, Taman Bukit Indah, Taman Ukay Perdana, and Kampung Ampang Campuran.
“In this district, there is one dengue hotspot locality, namely Kampung Bukit Sungai Puteh. Overall, dengue cases in the district are under control,” he said.
Hasrolnizam noted that MPAJ received a RM228,500 allocation from the state government through the Selangor Public Health Standing Committee to implement the Dengue Fever Control and Prevention Programme.
The funds are being used for enforcement measures, health education programmes, public awareness campaigns, and the activation of the Communication for Behavioural Impact (COMBI) volunteer teams within local communities.
He said the council also introduced the Coffee and COMBI programme to encourage public participation in dengue eradication efforts through neighbourhood clean-up and recycling activities.
“Each household that clears its premises of Aedes breeding sites and brings recyclable items weighing at least 5kg to the 'Trash to Cash' counter can redeem a complimentary cup of coffee at the designated counter,” Hasrolnizam said.
