​Invasive Mosquito Not Eradicated in Fuerteventura

Invasive Mosquito Not Eradicated in Fuerteventura

It is reported this week that the Aeges aegypti mosquito that was widely detected in Fuerteventura in December last year is now controlled, but has not been eradicated. This mosquito is a transmitter of diseases such as yellow fever and dengue.

Jose Juan Aleman, Director of Public Health of the Government of the Canary Islands released a press release to explain that the surveillance programme instigated across Fuerteventura since December show evidence of these mosquitoes in the urbanisation of Las Granadas in Puerto del Rosario.

Aleman pointed out that the Aeges aegypti mosquito situation is controlled, but that it will be necessary to wait 18 months from the discovery of specimens or eggs, as stipulated by the protocol issued by the World Health Organisation (WHO) to finally declare its eradication.

Specifically, it will be around the middle of May 2019 when the period ends, but since the end of December, Aeges aegypti mosquitoes have not been detected on the island despite the meteorological circumstances, such as rain that encourages hatching to take place. Therefore, there is still a real risk that there may be some eggs in remote places that could hatch, so surveillance will be maintained.

Basilio Valladares, Director of the University Institute of Tropical Diseases and Public Health of the Canary Islands has counted 35 adult mosquito specimens, and several of these were female, as well as larvae detected in Fuerteventura. He also explained that the place of origin of these specimens is not known, and the mutations that they have of their genome have not given any indication of being able to affirm exactly where they come from. However, he did suggest that one explanation could be mosquito eggs arrived on the island when someone illegally put a plant in a suitcase for planting in a private garden, but this theory can only be confirmed with further investigations.
