Asia’s burgeoning airline network is helping spread the dengue virus (DENV) across the continent says this new study. It found that air traffic volumes and connections explain DENV migration across Asia better than socio-economic and environmental factors like gross domestic product (GDP) and conducive temperatures. Central air hubs such as those in China, India, Singapore and Thailand contribute more to the diffusion of dengue compared to less busy routes. The findings suggest that future trends in global mobility could potentially accelerate the appearance and diffusion of DENV worldwide.
