IRD/IMéRA Cycle on Sustainable Development seminary :

Spread and control of mosquito-borne diseases in a changing world

December 18th, 2018, 10-12:30

Maison des astronomes, IMéRA,

2, place Le Verrier 13004 Marseille

Free entry

Organized and chaired by Mercedes Pascual (IMéRA resident, 2018-2019, Department of Ecology and Evolution, University of Chicago).

Infectious diseases transmitted by mosquito vectors are thriving under increased urbanization, socio-economic inequality, and environmental changes. The talks in this symposium will address the spatio-temporal variation of established and emerging infections transmitted by mosquito vectors in the developing world, as well as the associated challenge of effective control efforts.

Diffusion of emerging diseases in cities: does heterogeneity of the socio-economic environment matter?

The classical model of geography stipulates that within urban spaces, economically deprived areas have been the most affected by major infectious diseases such as cholera and plague. The current rise of emerging diseases today in urban areas worldwide calls this model into question. In particular dengue is one of the major modern urban diseases that have swept through the tropics and subtropics over recent decades. It provides us with a unique case with which to understand the link between urbanization and emerging disease. Although several studies suggest that dengue risk cannot be predicted based solely on socio-economic factors, this does not mean that these factors do not play a major role in the spread of the disease within cities. After presenting a few examples of such a link, I will describe the opportunity offered by open source data (census and other environmental data) to develop an understanding of the connection between socio-economic heterogeneity and the spatio-temporal spread of infectious diseases in Asia.

Mosquito control strategies in an urban environment - where is the World Health Organization taking us?

In response to the global expansion and re-emergence of vector-borne diseases, WHO launched the Global Vector Control Response program in 2017. The aim is to strengthen vector control through increased capacity, innovation, improved surveillance, better coordination and integrated action. Will this "new" approach overcome the failings of previous initiatives?

Spatiotemporal dynamics of malaria in West Africa: challenges for new sustainable control strategies

Malaria transmission is highly heterogeneous through time and space, and mapping of this heterogeneity is necessary to better understand local dynamics. Based on epidemiological analysis, the presentation will focus on the determination of hotspots and associated environmental risk factors including urbanization and land-use change, and on patterns of asymptomatic carriage. Targeting local persistent transmission and epidemiological changes is necessary to maintain efficient control, but also to deploy sustainable elimination strategies against identified transmission bottlenecks such as the reservoir of subpatent infections. Such decision-making tools are paramount to allocate resources based on sound scientific evidence and public health priorities.

 

About the IRD/IMéRA Cycle on Sustainable Development

As explicitly admitted in the UN’s Sustainable Development Objectives (SDOs), human development can only be conceived on a global scale considering the multiple interactions—economic (trade, outsourcing, etc.), demographic (migrations, epidemics, etc.), cultural (connectivity, networks, etc.) and environmental (global warming, etc.)—at play between North and South countries. These aspects are at the heart of the IMéRA Program “Global phenomena and regulation” (see https://imera.hypotheses.org/le-programme-phenomenes-globaux-et-regulation) and they are a fortiori even more salient the IRD research, IRD being one of the significant national and international players in the SDO’s agenda (see https://en.ird.fr/the-research).

The research cycle “Sustainable Development” held at IMéRA in this academic year 2018/2019 is designed to strengthen cooperation between IRD and IMéRA on sustainable development research through the dedicated joint chair hosted by IMéRA.  In 2018/2019, the cycle is managed by the IRD/IMéRA co-chair holders, Andrew Dobson (Princeton Univ.) and Mercedes Pascual (Univ. of Chicago), together with IMéRA director general and director of the “Global phenomea and regulation” program, Raouf Boucekkine (AMU). The first event took take place at IMéRA on October 19th 2018.
