[Mosquito-borne arboviruses and pregnancy: pathological consequences for the mother and infant. A general review]

Vertical transmission of arboviruses, mainly those transmitted by mosquitoes, was considered for a long time as an exceptional event in pregnant women. However, during the recent years, as a result of the global upsurge of these viral infections, several surveys and reports clearly demonstrated that the resulting pathologies were increasing in both severity and frequency in endemic countries where pregnant women are at risk. In order to better assess such new epidemiological trends, the authors performed a general review as exhaustive as possible of the pathological consequences of the infection during pregnancy caused by the four dengue viruses and Japanese encephalitis, West Nile and Chikungunya viruses. At the therapeutic and preventive levels we are quite unarmed in the face of such severe accidents as their pathogenesis remains presently unclear
