We report a full-term neonate presenting with symptomatic congenital cytomegalovirus (CMV) infection with hepatosplenomegaly, 'blueberry muffin' rash, intracranial calcifications, thrombocytopenia and respiratory distress. Maternal history was relevant for Guillain-Barré syndrome (GBS) during the first trimester of pregnancy. CMV infection is an important cause of GBS; thus, women presenting GBS during pregnancy should be screened for CMV infection. If positive, they may benefit from specialised monitoring and treatment in the antenatal period, which may decrease the risk of major neurodevelopmental sequelae of congenital CMV in the neonate...

Sporadic Zika virus infections had only occurred in Africa and Asia until an outbreak in Micronesia (Oceania) in 2007. In 2013 to 2014, several outer Pacific Islands reported local outbreaks. Soon thereafter, the virus was likely introduced in Brazil from competing athletes from French Polynesia and other countries that participated in a competition there. Transmission is thought to have occurred through mosquito bites and spread to the immunologically naive population. Being also a flavivirus, the Zika virus is transmitted by the Aedes mosquito that is endemic in South and Central America that is also the vector of West Nile virus, dengue, and chikungunya...

PURPOSE OF REVIEW: Zika virus (ZIKV) is the latest 'emerging virus' that has affected the Americas. First identified in the mid-20th century in Uganda, it was described as a vector arthropod-borne virus (arbovirus) and subsequently found capable of producing illness in humans. The illness was not different from other flavivirus infections and caused a relatively mild disease characterized by low-grade fever, nonspecific exanthem, nonpurulent conjunctivitis, and mild to moderate arthralgia...

Guillain-Barré syndrome has been reported in pregnancy and is a potentially lethal condition. It affects the nervous system with acute onset of symmetric ascending weakness and may result in frank respiratory failure and autonomic dysfunction. Most patients recall symptoms of a respiratory or gastrointestinal illness in the weeks preceding the onset of weakness. Recent evidence suggests a potential role of the Zika virus as a trigger for the syndrome. The diagnosis of Guillain-Barré is clinical. Supportive measures include venous thromboembolism prophylaxis, aggressive physical therapy, pressure ulcer prevention, enteral nutrition, and respiratory support...

Zika virus is an emerging mosquito-borne flavivirus that typically causes an asymptomatic infection or mild illness, although infection during pregnancy is a cause of microcephaly and other serious brain abnormalities. Guillain-Barré syndrome and other neurologic complications can occur in adults after Zika virus infection. However, there are few published reports describing postnatally acquired Zika virus disease among children. During January 2015-July 2016, a total of 158 cases of confirmed or probable postnatally acquired Zika virus disease among children aged <18 years were reported to CDC from U...

Zika virus is a mosquito-borne flavivirus primarily transmitted to humans by Aedes aegypti mosquitoes (1). Zika virus infections have also been documented through intrauterine transmission resulting in congenital infection; intrapartum transmission from a viremic mother to her newborn; sexual transmission; blood transfusion; and laboratory exposure (1-5). Most Zika virus infections are asymptomatic (1,6). Clinical illness, when it occurs, is generally mild and characterized by acute onset of fever, maculopapular rash, arthralgia, or nonpurulent conjunctivitis...

Over the past year, the Zika virus, an arthropod-borne Flavivirus, has transitioned from a relatively unknown tropical disease to the cause of a public health emergency. The Zika virus is transmitted by the Aedes species of mosquito as well as by sexual intercourse. Although the symptoms of acute Zika virus infection are usually mild and self-limited, it causes fetal microcephaly in pregnant women, and is associated with an increased risk of Guillain-Barré syndrome. The risk of microcephaly from Zika virus infection is estimated to be highest in women who are infected during the first trimester of pregnancy...

Zika virus is a flavivirus transmitted primarily by Aedes aegypti and Aedes albopictus mosquitoes, and infection can be asymptomatic or result in an acute febrile illness with rash (1). Zika virus infection during pregnancy is a cause of microcephaly and other severe birth defects (2). Infection has also been associated with Guillain-Barré syndrome (GBS) (3) and severe thrombocytopenia (4,5).

Before 2007, Zika virus (ZIKV) was generally considered as an arbovirus of low clinical relevance, causing a mild self-limiting febrile illness in tropical Africa and Southeast Asia. Currently, a large, ongoing outbreak of ZIKV that started in Brazil in 2015 is spreading across the Americas. Virus infection during pregnancy has been potentially linked to congenital malformations, including microcephaly. In addition to congenital malformations, a temporal association between ZIKV infection and an increase in cases of Guillain-Barré syndrome is currently being observed in several countries...

A strong causal association has become evident between Zika virus (ZIKV) infection during pregnancy and the occurrence of fetal growth restriction, microcephaly and eye defects. Circumstantial evidence is presented in this paper in support of the hypothesis that these effects, as well as the Guillain-Barré syndrome, are due to an endogenous form of hypervitaminosis A resulting from ZIKV infection-induced damage to the liver and the spillage of stored vitamin A compounds ("retinoids") into the maternal and fetal circulation in toxic concentrations...

The current Zika outbreak is largest of its kind with 1.4 million cases in Brazil alone. World Health Organization declared the current outbreak as the public health emergency of international concerns. The major route of Zika virus transmission is mosquito bites. Sexual transmission and monkey bites are also observed in few cases. There is dire need to evaluate the other routes of transmission like blood transfusion, lactation and contact with body fluids. Zika virus is infecting infants, not only causing microcephaly but also creating number of complications resulting in bad outcomes of pregnancy...

Infection with Asian-lineage Zika virus (ZIKV) has been associated with Guillain-Barré syndrome and fetal abnormalities, but the underlying mechanisms remain poorly understood. Animal models of infection are thus urgently needed. Here we show that rhesus macaques are susceptible to infection by an Asian-lineage ZIKV closely related to strains currently circulating in the Americas. Following subcutaneous inoculation, ZIKV RNA is detected in plasma 1 day post infection (d.p.i.) in all animals (N=8, including 2 pregnant animals), and is also present in saliva, urine and cerebrospinal fluid...

Zika virus has rapidly spread through the World Health Organization's Region of the Americas since being identified in Brazil in early 2015. Transmitted primarily through the bite of infected Aedes species mosquitoes, Zika virus infection during pregnancy can cause spontaneous abortion and birth defects, including microcephaly (1,2). New York City (NYC) is home to a large number of persons who travel frequently to areas with active Zika virus transmission, including immigrants from these areas. In November 2015, the NYC Department of Health and Mental Hygiene (DOHMH) began developing and implementing plans for managing Zika virus and on February 1, 2016, activated its Incident Command System...

Zika virus was originally identified in a sentinel rhesus monkey in the Zika Forest of Uganda in 1947. The virus is a member of the family Flaviviridae, genus Flavivirus, and is transmitted to humans by Aedes species mosquitoes. The first report of Zika virus outside Africa and Asia was in 2007 when the virus was associated with a small outbreak in Yap State, part of the Federated States of Micronesia. Since then, Zika virus infections have been reported around the world, including in southeast Asia; French Polynesia and other islands in the Pacific Ocean; and parts of South, Central, and North America...

Zika virus (ZIKV), a relative newcomer from the flavivirus group that includes dengue, Japanese encepahalitis and yellow fever, is one of the emerging pathogens that is fast transcending geographical boundaries. It is a vector-borne disease transmitted by the same Aedes aegypti and Aedes albopictus, which cause dengue and chikungunya. In addition to the vector-mediated transmission of Zika fever, probable human-to-human transmission through exchange of body fluids, including sexual and perinatal transmission and through blood transfusion, makes containment of this new entity more challenging...

BACKGROUND: As Zika virus continues to spread, decisions regarding resource allocations to control the outbreak underscore the need for a tool to weigh policies according to their cost and the health burden they could avert. For example, to combat the current Zika outbreak the US President requested the allocation of $1.8 billion from Congress in February 2016. METHODOLOGY/PRINCIPAL FINDINGS: Illustrated through an interactive tool, we evaluated how the number of Zika cases averted, the period during pregnancy in which Zika infection poses a risk of microcephaly, and probabilities of microcephaly and Guillain-Barré Syndrome (GBS) impact the cost at which an intervention is cost-effective...
