Dengue fever is on the rise again, with at least 100 cases recorded every week.

Deputy Health Minister Datuk Seri Dr Hilmi Yahaya said the ministry was still actively carrying out anti-Aedes activities to reduce the number of dengue cases.

He said that until last Friday, over 2,000 dengue cases were reported nationwide.

"This figure is worrying us, with Selangor still top of the chart in the number of dengue fever cases recorded.

"This is probably due to its high population density compared to the other states, making its efforts to eradicate Aedes mosquitoes less effective."

Dr Hilmi said this to reporters after the handing-out of 1Malaysia People's Aid (BR1M) to 789 recipients from the Bayan Lepas state constituency at Sekolah Menengah Teluk Kumbar 2, here, today.

"In densely populated areas, it is difficult to control dumping of rubbish, littering and the drainage system," he said.

Therefore, he urged the public to keep their surroundings clean and organise gotong-royong each week to get rid of Aedes breeding grounds, and not just wait for the local authority workers to do the job.

Dr Hilmi said 2,885 dengue cases were recorded last week, an increase of 100 cases from the 2,785 recorded the previous week.
