Abstract

Summ a r yThe current outbreak of Zika virus (ZIKV) infection has been associated with an apparent increased risk of congenital microcephaly.We describe a case of a pregnant woman and her fetus infected with ZIKV during the 11th gestational week.The fetal head circumference decreased from the 47th percentile to the 24th percentile between 16 and 20 weeks of gestation.ZIKV RNA was identified in maternal serum at 16 and 21 weeks of gestation.At 19 and 20 weeks of gestation, substantial brain abnormalities were detected on ultrasonography and magnetic resonance imaging (MRI) without the presence of microcephaly or intracranial calcifications.On postmortem analysis of the fetal brain, diffuse cerebral cortical thinning, high ZIKV RNA loads, and viral particles were detected, and ZIKV was subsequently isolated.Z ika virus (ZIKV), a mosquito-borne flavivirus and member of the Flaviviridae family, was originally isolated from a sentinel primate in Uganda in 1947. 1 ZIKV was associated with mild febrile disease and maculopapular rash in tropical Africa and some areas of Southeast Asia.Since 2007, ZIKV has caused several outbreaks outside its former distribution area in islands of the Pacific: in 2007 on Yap island in Micronesia, in 2013 and 2014 in French Polynesia, and in 2015 in South America, where ZIKV had not been identified previously.[2][3][4][5] There are separate African and Asian lineages of the virus, 6 and the latter strains have caused the outbreaks in the Pacific and the Americas.7 As in the transmission of dengue and chikungunya viruses, the main transmission cycle of ZIKV occurs between urban aedes mosquitoes and humans.One striking feature of the current ZIKV outbreak is the apparent increased risk of intrauterine or perinatal transmission of the virus as well as the marked increase in the number of newborns with microcephaly reported in Brazil.[8][9][10][11][12][13][14][15][16][17] A recent prospective study showed fetal ultrasonographic abnormalities in 12 of 42 women (29%) with ZIKV infection during pregnancy; 7 of the 42 fetuses (17%) that were studied had microcephaly, cerebral atrophy, or brain calcifications.11 Because of the association between ZIKV infection and microcephaly and other neurologic disorders, the World Health Organization has declared the ZIKV epidemic a public health emergency of international concern.13 Early in this particular outbreak, investigations into the viral pathogenesis, vertical transmission rates, potential viral cofactors, and sensitivity and specificity of diagnostic testing have presented more questions than answers.Nevertheless, the Centers for Disease Control and Prevention (CDC) has issued a travel advisory The authors' full names, academic degrees, and affiliations are listed in the Appendix.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
