  • New Caledonia - Wolbachia project 1 year later: half of mosquitoes are believed to be carriers of the bacteria today

    September 30, 2020

    For the moment, on the Caillou, only Nouméa is experimenting with the device. The first mosquitoes carrying Wolbachia bacteria were released a little over a year ago. For the World Mosquito Program, which carries the project, the first assessment is positive.

    Impossible to differentiate them, yet they are there, all around us.
    Mosquitoes carrying Wolbachia. A natural bacteria, presented as harmless which reduces the ability of mosquitoes to transmit diseases such as dengue, Zika or chikungunya.
    On average throughout the municipality, we are roughly half of the mosquitoes that are carriers of the Wolbachia bacteria. It varies depending on the area, others are 70% carrier and others a little less. That's why we would like to intervene a second time from the month of December.

    Less dengue this year, is that a sign?

    There have been few cases of dengue this year. Could it be thanks to the Wolbachia bacteria? At this stage Nadège Rossi prefers to remain cautious:


    " It is still a bit early to put them in touch, it is true that generally we have had few cases of dengue, whether in Nouméa or in other municipalities this year. That said, in the cases that we have observed, where we had high levels of Wolbachia, we have seen that there were no transmissions on people with dengue. 'other neighborhoods, where we could see epidemic foci, we realized that Wolbachia were not well established."
    Pour l’instant, sur le Caillou, seule Nouméa expérimente le dispositif. Les premiers moustiques porteurs de la bactérie Wolbachia ont été lâchés i
