Chikungunya fever CF is an arboviral disease in worldwide expansion due to the plasticity of its pathogen and vector. Chikungunya virus CHIKV , a positive-sense, singlestranded RN" alphavirus, is transmitted by Aedes Stegomyia aegypti and Aedes albopictus mosquitoes, two hegemonic anthropophilic day-biting mosquitoes capable of colonizing very different environments. This expert review discusses the molecular epidemiology, pathophysiology, clinical features, diagnosis, management, and prevention of CF during pregnancy, infancy, and childhood. Specifically, it will focus not only on the issue and challenges of perinatal mother-to-child transmission of CHIKV, its pathogenesis, and effects on neurodevelopment, but also on CHIKV-associated central nervous system disease in children, two previously ill-characterized features of the infection.
