Training commenced this week in Suva, Fiji, aimed at assisting Pacific health professionals in tracking mosquito resistance to insecticides.
The Pacific Mosquito Surveillance Strengthening for Impact (PacMOSSI) program encompasses various activities, such as identifying mosquito species to determine their local distributions, collecting larvae, and breeding Aedes mosquitoes for testing.
Mosquito populations are abundant in the Pacific. A 2023 PacMOSSI report indicated that over 42 species of Anopheles mosquitoes inhabit New Guinea, the Solomon Islands, and Vanuatu. Additionally, the Aedes genus includes 119 species in the region, while the Culex genus comprises 113 different species.
Many of these species can transmit various diseases, such as malaria and dengue.
The report noted that different mosquito species are responsible for spreading distinct pathogens among animal hosts, though not all mosquito species can transmit pathogens.
Dengue prevention is crucial in reducing the incidence of this mosquito-borne viral infection, which can lead to severe illness. Key strategies include eliminating breeding sites for mosquitoes by removing standing water in containers, gutters, and other areas. Using insect repellent containing DEET, picaridin, or oil of lemon eucalyptus can help protect individuals from bites, especially during peak mosquito activity periods. Installing window and door screens, wearing long-sleeved clothing, and using mosquito nets at night also contribute to personal protection. Community awareness and participation in clean-up campaigns are essential, as these encourage collective action to minimize mosquito populations. Vaccination may also be an option in some regions, providing an additional layer of defense against the virus. By combining these efforts, communities can significantly reduce the risk of dengue outbreaks.
