Zika Virus Net is the web resource for anyone interested in Zika virus. Zika virus (ZIKV) is an insect-borne virus, of the flavivirus genus, that is spread by Aedes mosquitoes. The most common symptoms of Zika virus disease (Zika) are fever, rash, joint pain, and red eye. The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon. The symptoms of Zika are similar to those of dengue and chikungunya, which are diseases caused by other viruses spread by the same type of mosquitoes. Zika virus can be spread from a pregnant woman to her unborn baby. There have been reports of a serious birth defect of the brain called microcephaly and other poor pregnancy outcomes in babies of mothers who were infected with Zika virus while pregnant. On February 1st, 2016, the WHO declared the Zika outbreak as a Public Health Emergency of International Concern (PHEIC). As of August 2017 the number of new Zika virus cases in the Americas had fallen dramatically.

The objectives of Zika Virus Net are to be the public and professional information resource for zika fever and to serve as a network in the exchange of information and news related to zika.

  Yellow Fever, Zika virus, Dengue, Chikungunya -- France
  A potentially deadly mosquito that can carry viruses such as yellow fever and Zika has been spotted in Brittany, northern France, sparking fears they may soon land on British shores. Asian tiger mosquitoes [_Aedes albopictus_] have been confirmed to be in the commune of Domagne in the department of Ile-et-Vilaine in western Brittany.
  Health authorities are preparing an intensive campaign to rid the area of the insects with strong insecticides.

• Zika virus replication on endothelial cells and invasion into the central nervous system by inhibiting interferon β translation Thu, 30 Mar 2023 06:00:00 -0400
  The blood-brain barrier (BBB) is one of the tightest physical barriers to prevent pathogens from invading the central nervous system (CNS). However, the mechanism by which Zika virus (ZIKV) crossing the BBB remains unresolved. We found ZIKV induced high morbidity and mortality in newborn mice, accompanied by inflammatory injury on CNS. ZIKV was found to replicate primarily in the cortex and hippocampus in neonatal mouse brains. An in vitro model revealed that ZIKV had no impact on hBMECs...
• Gain without pain: Adaptation and increased virulence of Zika virus in vertebrate host without fitness cost in mosquito vector Thu, 30 Mar 2023 06:00:00 -0400
  Zika virus (ZIKV) is now in a post-pandemic period, for which the potential for re-emergence and future spread is unknown. Adding to this uncertainty is the unique capacity of ZIKV to directly transmit between humans via sexual transmission. Recently, we demonstrated that direct transmission of ZIKV between vertebrate hosts leads to rapid adaptation resulting in enhanced virulence in mice and the emergence of three amino acid substitutions (NS2A-A117V, NS2A- A117T, and NS4A-E19G) shared among...

• Antibody Immunity to Zika Virus among Young Children in a Flavivirus-Endemic Area in Nicaragua Thu, 30 Mar 2023 06:00:00 -0400
  Objective: To understand the dynamics of Zika virus (ZIKV)-specific antibody immunity in children born to mothers in a flavivirus-endemic region during and after the emergence of ZIKV in the Americas. Methods: We performed serologic testing for ZIKV cross-reactive and type-specific IgG in two longitudinal cohorts, which enrolled pregnant women and their children (PW1 and PW2) after the beginning of the ZIKV epidemic in Nicaragua. Quarterly samples from children over their first two years of life...
• Role of the Microbiome in Aedes spp. Vector Competence: What Do We Know? Thu, 30 Mar 2023 06:00:00 -0400
  Aedes aegypti and Aedes albopictus are the vectors of important arboviruses: dengue fever, chikungunya, Zika, and yellow fever. Female mosquitoes acquire arboviruses by feeding on the infected host blood, thus being able to transmit it to their offspring. The intrinsic ability of a vector to infect itself and transmit a pathogen is known as vector competence. Several factors influence the susceptibility of these females to be infected by these arboviruses, such as the activation of the innate...
• Host Cell Targets for Unconventional Antivirals against RNA Viruses Thu, 30 Mar 2023 06:00:00 -0400
  The recent COVID-19 crisis has highlighted the importance of RNA-based viruses. The most prominent members of this group are SARS-CoV-2 (coronavirus), HIV (human immunodeficiency virus), EBOV (Ebola virus), DENV (dengue virus), HCV (hepatitis C virus), ZIKV (Zika virus), CHIKV (chikungunya virus), and influenza A virus. With the exception of retroviruses which produce reverse transcriptase, the majority of RNA viruses encode RNA-dependent RNA polymerases which do not include molecular...
• Vector Competence for Zika Virus Changes Depending on the Aedes aegypti's Region of Origin in Manaus: A Study of an Endemic Brazilian Amazonian City Thu, 30 Mar 2023 06:00:00 -0400
  Zika virus (ZIKV) is transmitted to humans by the infectious bite of mosquitoes such as Aedes aegypti. In a city, the population control of mosquitoes is carried out according to alerts generated by different districts via the analysis of the mosquito index. However, we do not know whether, besides mosquito abundance, the susceptibility of mosquitoes could also diverge among districts and thus impact the dissemination and transmission of arboviruses. After a viremic blood meal, the virus must...
• Growth Velocity and Nutritional Status in Children Exposed to Zika Virus during Pregnancy from Amazonas Cohort, Brazil Thu, 30 Mar 2023 06:00:00 -0400
  The high incidence of Zika virus (ZIKV) infection in the period of 2015-2016 in Brazil may have affected linear height growth velocity (GV) in children exposed in utero to ZIKV. This study describes the growth velocity and nutritional status based on the World Organization (WHO) standards of children exposed to ZIKV during pregnancy and followed up in a tertiary unit, a reference for tropical and infectious diseases in the Amazon. Seventy-one children born between March 2016 and June 2018 were...
• Identification of Zika Virus NS1-Derived Peptides with Potential Applications in Serological Tests Thu, 30 Mar 2023 06:00:00 -0400
  Zika virus (ZIKV), a mosquito-borne pathogen, is an emerging arbovirus associated with sporadic symptomatic cases of great medical concern, particularly among pregnant women and newborns affected with neurological disorders. Serological diagnosis of ZIKV infection is still an unmet challenge due to the co-circulation of the dengue virus, which shares extensive sequence conservation of structural proteins leading to the generation of cross-reactive antibodies. In this study, we aimed to obtain...
• Zika Virus Infection Damages the Testes in Pubertal Common Squirrel Monkeys (Saimiri collinsi) Thu, 30 Mar 2023 06:00:00 -0400
  During the Zika virus (ZIKV) outbreak and after evidence of its sexual transmission was obtained, concerns arose about the impact of the adverse effects of ZIKV infection on human fertility. In this study, we evaluated the clinical-laboratory aspects and testicular histopathological patterns of pubertal squirrel monkeys (Saimiri collinsi) infected with ZIKV, analyzing the effects at different stages of infection. The susceptibility of S. collinsi to ZIKV infection was confirmed by laboratory...
