The release of Wolbachia-infected Aedes mosquitoes has led to a 50 to 80 per cent drop in dengue cases in several outbreak areas in Selangor, the Dewan Rakyat was told. Health Minister Datuk Seri Dr Dzulkefly Ahmad said public health studies conducted during the early phase of the programme showed encouraging results. “During the early phase of implementation, the results of public health studies in six dengue outbreak localities in Selangor showed a reduction in dengue cases between 50 per cent and 80 per cent compared with control localities,” he said in a written parliamentary reply last night. He was responding to Mohd Hasnizan Harun (PN-Hulu Selangor), who asked whether the ministry has conducted comprehensive environmental and public health impact studies related to the release of Wolbachia-infected mosquitoes. Hasnizan also asked about continuous monitoring mechanisms to ensure long-term safety. Dzulkefly said the early assessments also examined the interaction between Wolbachia-infected Aedes mosquitoes and the existing mosquito population in the environment.
