Introduction

Zika virus world map (CDC 2016)
Zika Virus Pregnancy USA (2015-2016)
Zika Virus Pregnancy USA (2015-2016)[1]

Zika virus (ZIKV) is a mosquito-borne flavivirus related to dengue virus first isolated from a rhesus monkey in Zika forest, Uganda (1947). Transmitted by mosquitoes (Aedes aegypti) it was then identified in humans in Nigeria in 1954 and subsequently in South America, Asia and Pacific regions. More recently in Australia from returning travellers.[2]

Mosquito lifecycle

Mosquito bites lead to an initial infection of skin cells.[3] The virus may also be transmitted transplacentally or during delivery.[4]

Now good evidence, from Brazil and other South American countries, for association with neural abnormalities (microcephaly, vision development, Guillian Barre Syndrome). This possible association in other developmental systems requires more clinical and scientific evidence before being confirmed.


"Although a causal link between Zika infection in pregnancy and microcephaly - and I must emphasise - has not been established, the circumstantial evidence is suggestive and extremely worrisome" (Margaret Chan, WHO General Director).

Some Recent Findings

Microlissencephaly MRI-01.jpg

  • Congenital Zika Virus Infection: Beyond Neonatal Microcephaly[5] "Recent studies have reported an increase in the number of fetuses and neonates with microcephaly whose mothers were infected with the Zika virus (ZIKV) during pregnancy. To our knowledge, most reports to date have focused on select aspects of the maternal or fetal infection and fetal effects. To describe the prenatal evolution and perinatal outcomes of 11 neonates who had developmental abnormalities and neurological damage associated with ZIKV infection in Brazil....Three of 11 neonates died, giving a perinatal mortality rate of 27.3%. The median (SD) cephalic perimeter at birth was 31 (3) cm, a value lower than the limit to consider a microcephaly case. In all patients, neurological impairments were identified, including microcephaly, a reduction in cerebral volume, ventriculomegaly, cerebellar hypoplasia, lissencephaly with hydrocephalus, and fetal akinesia deformation sequence (ie, arthrogryposis). Results of limited testing for other causes of microcephaly, such as genetic disorders and viral and bacterial infections, were negative, and the ZIKV genome was found in both maternal and neonatal tissues (eg, amniotic fluid, cord blood, placenta, and brain)."
  • Modeling Zika Virus Infection in Pregnancy[6] "Collectively, the findings from the stud- ies in mice support the hypothesis that infection during pregnancy with contemporary ZIKV strains causes placental infection and injury and that ZIKV spreads to the fetal brain and kills neuronal progenitor cells, which probably con- tributes to the microcephaly and other congeni- tal malformations that have been observed in human neonates."
  • Clinical features and neuroimaging (CT and MRI) findings in presumed Zika virus related congenital infection and microcephaly: retrospective case series study[7] "23 children with a diagnosis of congenital infection presumably associated with the Zika virus during the Brazilian microcephaly epidemic. Types of abnormalities and the radiological pattern of lesions identified on CT and MRI brain scans. Six of the 23 children tested positive for IgM antibodies to Zika virus in cerebrospinal fluid. The other 17 children met the protocol criteria for congenital infection presumably associated with the Zika virus, even without being tested for IgM antibodies to the virus-the test was not yet available on a routine basis. Of the 23 children, 15 underwent CT, seven underwent both CT and MRI, and one underwent MRI. ...Severe cerebral damage was found on imaging in most of the children in this case series with congenital infection presumably associated with the Zika virus. The features most commonly found were brain calcifications in the junction between cortical and subcortical white matter associated with malformations of cortical development, often with a simplified gyral pattern and predominance of pachygyria or polymicrogyria in the frontal lobes. Additional findings were enlarged cisterna magna, abnormalities of corpus callosum (hypoplasia or hypogenesis), ventriculomegaly, delayed myelination, and hypoplasia of the cerebellum and the brainstem."
  • Zika Virus Infection with Prolonged Maternal Viremia and Fetal Brain Abnormalities[8] "The 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."
  • Zika virus outbreaks prompt warnings to pregnant women[9] "The rapid spread of Zika virus in the Americas, where there is little population immunity, is a major concern, especially given the possible link between infection during pregnancy and the congenital abnormality microcephaly, the World Health Organization has warned. Margaret Chan, WHO’s director general, said, “Although a causal link between Zika infection in pregnancy and microcephaly has not been established, the circumstantial evidence is suggestive and extremely worrisome. An increased occurrence of neurological syndromes, noted in some countries coincident with arrival of the virus, adds to the concern."
  • Ocular Findings in Infants With Microcephaly Associated With Presumed Zika Virus Congenital Infection in Salvador, Brazil[10] "Twenty-three of 29 mothers (79.3%) reported suspected ZIKV infection signs and symptoms during pregnancy, 18 in the first trimester, 4 in the second trimester, and 1 in the third trimester. Of the 29 infants (58 eyes) examined (18 [62.1%] female), ocular abnormalities were present in 17 eyes (29.3%) of 10 children (34.5%). Bilateral findings were found in 7 of 10 patients presenting with ocular lesions, the most common of which were focal pigment mottling of the retina and chorioretinal atrophy in 11 of the 17 eyes with abnormalities (64.7%), followed by optic nerve abnormalities in 8 eyes (47.1%), bilateral iris coloboma in 1 patient (2 eyes [11.8%]), and lens subluxation in 1 eye (5.9%)."

Zika History

Zika virus (ZIKV) is a mosquito-borne flavivirus related to dengue virus first isolated from a rhesus monkey in Zika forest, Uganda (1947), Africa. Transmitted by mosquitoes (Aedes aegypti) it was then identified in humans in Nigeria in 1954 and subsequently in South America, Asia and Pacific regions. More recently in Australia from returning travellers.[12]

Pyriproxyfen

Pyriproxyfen structure
Pyriproxyfen structure

(C20H19NO3) A chemical larvicide used to control mosquito populations, and therefore mosquito-bourns infections. A juvenile hormone analog to insect growth regulator (IGR), inhibiting metamorphosis and embryogenesis in several insects. Suggested that the chemical exposure can act at two levels; firstly the blood-fed females may carry the chemical to the larval habitats, thereby inhibiting adult emergence;secondly that tarsal contact with the chemical may inhibit egg maturation in adult mosquitoes.[13]

Vision Abnormalities

Some viral infections (herpes and rubella) are known to cause developmental vision abnormalities. A clinical study[10] of infants from Zika infected mothers in Brazil have described vision abnormalities including:

  • bilateral ocular lesions
  • focal pigment mottling of the retina
  • chorioretinal atrophy
  • optic nerve abnormalities
iris coloboma
