Control Measures
Multi-media campaigns for Public Health awareness are ongoing with emphasis on the importance of cleanliness and reduction of breeding sites for mosquitoes.
The Ministry of Health also drives a multi-sectoral approach for the National Vector Control Committee involving various Government ministries and other organizations to assist in mobilising community engagement in source reduction and clean up campaigns, but also in funding response for vector-borne outbreaks.
The positive results from this Multi-Sectoral Committee model encourages budget allocation by each ministry and corporation of chemicals and supplies needed.
Vector Surveillance has instigated the laying of special traps and identification of types of mosquitoes captured. Testing for infected mosquitoes will soon be available locally.
Peri-focal spraying, fumigation and control efforts continues for selected sites.
Enhanced surveillance of DENV outbreak has engaged public and private clinical practices with CME refresher sessions. This includes refresher trainings on DENV management for peripheral clinical sites for Upolu and Savaii.
