title: [Entomological factors of arboviruses emergences].
abstract: Arboviruses - viruses transmitted by haematophagous arthropods - are responsible for febrile syndromes, which sometimes include haemorrhagic or neurological symptoms. Human activities have facilitated the emergence of these originally zoonotic viruses and the domestication and spread throughout the world of their major vectors. The last decade has seen significant changes in the epidemiology of arboviruses transmitted by mosquitoes of the genus Aedes, particularly in relation to the intercontinental spread of Aedes albopictus. Here, we address the epidemiological consequences of the invasion by this species into Central Africa and Europe in a context of viral globalization. The risk of transmission in these areas is influenced by virus-vector adaptation phenomena as well as environmental phenomena including climate. Faced with these new risks, it is essential to develop competences in entomological and virological surveillance, risk assessment and forecasting of epidemic risk in order to develop strategies for the prevention and control of epidemics.
