Brief Summary:

Dengue is the most common arbovirus worldwide (390 million people infected each year) and belongs to the Flavivirus genus of the Flaviviridae family like Zika. Its expansion has been rapid since the last decade with an increase in the number of cases of 400% and the first cases of indigenous dengue described in Europe.

Current data on the consequences of dengue fever on the fetus are incomplete. The risk of maternal-fetal transmission of dengue during the peripartum period has now been recorded in numerous case reports and a few case series for patients who contracted dengue in the 12 days preceding childbirth or at the time of delivery. However, the transmission of dengue is highly variable depending on the studies ranging from 1.6 to 15% and the consequences for the newborn are very variable ranging from simple thrombocytopenia to death in severe neonatal dengue.

Regarding the risk of malformation, a few old cases of heart disease, hydrocephalus and neural tube closure abnormalities have been described in the literature following exposure to dengue fever during pregnancy. Since no malformative case has been described, however, to our knowledge, no prospective study with specialized ultrasound monitoring has been performed for pregnant women who contracted dengue during their pregnancy.

Primary Outcome Measures :
  1. Study the teratogenic effects of the dengue virus on the fetus [ Time Frame: at childbirth ]
    Rate of fetal anomalies such as infectious fetal disease or any other fetal anomaly detected during specialized antenatal ultrasound follow-up.


Secondary Outcome Measures :
  1. Study the maternal-fetal transmission of dengue fever during pregnancy [ Time Frame: at childbirth ]
    Amniotic fluid positive dengue PCR (Polymerase Chain Reaction) rate

  2. Study the maternal-fetal transmission of dengue fever in the peri-partum [ Time Frame: at childbirth ]
    Umbilical cord dengue positive and / or IgM (immunoglobulin M) positive PCR rate

  3. Study the materno-placental transmission of dengue fever during pregnancy and peri-partum [ Time Frame: at childbirth ]
    Placental dengue positive PCR rate

  4. Study the consequences at the placental level of dengue, in terms of anatomopathological alterations [ Time Frame: at childbirth ]
    Placental pathology abnormalities rate
