Aedes aegypti and company
Soon afterwards, ducks carrying the H5N1 virus are found dead there. All birds in a contaminated poultry farm have to be culled. In France, the immediate economic impact of this outbreak on poultry breeders is unprecedented.
At around the same time, the Chikungunya virus arrives in Europe after an epidemic outbreak in the Indian Ocean.
In the same region, researchers are working to gain a better understanding of the mechanisms and conditions causing the spread of West Nile Virus, also borne by mosquitoes.
Towards operational surveillance of re-emergent diseases
Satellites obviously don’t track swarms of parasite-bearing mosquitoes or infected populations. Instead, they enable collection of health, climate and environment data that have a direct impact on ecosystems likely to harbour vectors of disease.
They are able to monitor factors that make diseases more likely to spread, such as stagnant water, wind or plant cover.
Emercase is just one project among many that should help to set up an early-warning system in Europe to assist health authorities.
