title: [Arboviruses and epizootic viruses].
abstract: Some viral diseases are transmitted to human by arthropods (arboviroses), or by animals (zoonoses). Among more than 500 arboviruses and epizootic viruses that are classified into seven families, only a few are responsible for zoonoses or cause severe human diseases. Infected patients may show an acute disease associated with different symptoms, ranging from high fever to encephalitis, pulmonary distress, and haemorrhages. Some diseases show one or more of these symptoms and the factors responsible for severe outcomes, either linked to the virus, or to the host, or to the vector, remain poorly understood. Arboviroses and zoonoses are emerging or re-emerging diseases that need a multidisciplinary effort to control the propagation of the infectious agent and the pathogenesis in infected patients. Some viruses could be used for bioterrorism attacks. In virology, studies on the interactions of the viruses with their vectors and vertebrate hosts and on the pathophysiology of the infections will allow a better prevention of these diseases.
