CNES and Sanofi Pasteur join forces to combat dengue fever

In response to the haemorrhagic dengue fever pandemic currently sweeping the planet, CNES and Sanofi Pasteur are joining forces to develop predictive mapping techniques for risk zones.

Global public health issue

Dengue fever is a viral infection borne by certain species of mosquito that today threatens nearly half of the world’s population.

The haemorrhagic form of the disease, which often requires hospital treatment, has become widespread in recent years and can swamp local health services in a matter of days.

The challenge facing CNES and Sanofi Pasteur is therefore to develop a model capable of predicting the risk of outbreaks of the disease to help health authorities prepare to respond.

To this end, CNES will be combining its expertise in tele-epidemiology and satellite imagery with that of scientists working in fields as varied as entomology (the study of insects), sociology, microbiology and meteorology.

New application for tele-epidemiology

This first-of-a-kind partnership between the French space agency and a leading player in healthcare will give CNES the opportunity to exploit the tele-epidemiology approach—based on risk maps compiled from satellite data to show when and where mosquitoes are likely to breed—that it has successfully developed to help combat Nile Valley fever and malaria.

In this context, the recent launch of the high-resolution Pléiades imaging satellite will pave the way for better detection and a closer understanding of the environmental factors that contribute to the onset of epidemics.

For Murielle Lafaye, in charge of developing environment, climate and health applications at CNES,in supplying the first link in the chain to combat this kind of disease through its expertise in satellite imagery, CNES is fully accomplishing its mission to get space working more for citizens.
