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.

- Suppression of Midgut Microbiota Impact Pyrethroid Susceptibility in Aedes aegypti Thu, 18 Aug 2022 06:00:00 -0400
Aedes aegypti is a mosquito that transmits viral diseases such as dengue, chikungunya, Zika, and yellow fever. The insect's microbiota is recognized for regulating several biological processes, including digestion, metabolism, egg production, development, and immune response. However, the role of the bacteria involved in insecticide susceptibility has not been established. Therefore, the objective of this study was to characterize the resident microbiota in a field population of A. aegypti to...
- Quantitative Trait Locus Determining the Time of Blood Feeding in Culex pipiens (Diptera: Culicidae) Wed, 17 Aug 2022 06:00:00 -0400
Mosquitoes and other blood feeding arthropods are vectors of pathogens causing serious human diseases, such as Plasmodium spp. (malaria), Wuchereria bancrofti (lymphatic filariasis), Borrelia burgdorferi (Lyme disease), and viruses causing dengue, Zika, West Nile, chikungunya, and yellow fever. Among the most effective strategies for the prevention of vector-borne diseases are those aimed at reducing human-vector interactions, such as insecticide applications and insecticide-treated bed nets...
- Lack of association of the KIR and HLA class I ligands with ZIKV infection in south and southeast of Brazil Wed, 17 Aug 2022 06:00:00 -0400
BACKGROUND: Zika virus (ZIKV) is an emerging arbovirus associated with foetal malformations and neurological complications. The infection is usually associated with mild symptoms. The comparison between the allelic frequency of polymorphic genes in symptomatic infected individuals in the population can clarify the pathogenic mechanisms of ZIKV. During ZIKV infection, cytokines are produced and natural killer (NK) cells are recruited, whose activation depends on signaling pathways activated by...
- Aquatic Flaviviruses Wed, 17 Aug 2022 06:00:00 -0400
Flaviviruses are positive-sense single-stranded RNA viruses, including some well-known human pathogens such as Zika, dengue, and yellow fever viruses, which are primarily associated with mosquito and tick vectors. The vast majority of flavivirus research has focused on terrestrial environments; however, recent findings indicate that a range of flaviviruses are also present in aquatic environments, both marine and freshwater. These flaviviruses are found in various hosts, including fish,...
- Quantitative electrostatic force tomography for virus capsids in interaction with an approaching nanoscale probe Wed, 17 Aug 2022 06:00:00 -0400
Electrostatic interactions are crucial for the assembly, disassembly and stability of proteinaceous viral capsids. Moreover, at the molecular scale, elucidating the organization and structure of the capsid proteins in response to an approaching nanoprobe is a major challenge in biomacromolecular research. Here, we report on a generalized electrostatic model, based on the Poisson-Boltzmann equation, that quantifies the subnanometric electrostatic interactions between an AFM tip and a...
- Spatial distribution of insecticide resistant populations of Aedes aegypti and Ae. albopictus and first detection of V410L mutation in Ae. aegypti from Cameroon Tue, 16 Aug 2022 06:00:00 -0400
CONCLUSIONS: This study revealed that Ae. aegypti and Ae. albopictus are resistant to multiple insecticide classes with multiple resistance mechanisms implicated. These findings could guide insecticide use to control arbovirus vectors in Cameroon.
- Zika virus causes placental pyroptosis and associated adverse fetal outcomes by activating GSDME Tue, 16 Aug 2022 06:00:00 -0400
Zika virus (ZIKV) can be transmitted from mother to fetus during pregnancy, causing adverse fetal outcomes. Several studies have indicated that ZIKV can damage the fetal brain directly; however, whether the ZIKV-induced maternal placental injury contributes to adverse fetal outcomes is sparsely defined. Here, we demonstrated that ZIKV causes the pyroptosis of placental cells by activating the executor gasdermin E (GSDME) in vitro and in vivo. Mechanistically, TNF-α release is induced upon the...
- XAF1 Protects Host against Emerging RNA Viruses by Stabilizing IRF1-Dependent Antiviral Immunity Tue, 16 Aug 2022 06:00:00 -0400
XIAP-associated factor 1 (XAF1) is an interferon (IFN)-stimulated gene (ISG) that enhances IFN-induced apoptosis. However, it is unexplored whether XAF1 is essential for the host fighting against invaded viruses. Here, we find that XAF1 is significantly upregulated in the host cells infected with emerging RNA viruses, including influenza, Zika virus (ZIKV), and SARS-CoV-2. IFN regulatory factor 1 (IRF1), a key transcription factor in immune cells, determines the induction of XAF1 during...
- Evidence that untranslated genomic sequences are key determinants of insect-specific flavivirus host restriction Mon, 15 Aug 2022 06:00:00 -0400
Most flaviviruses cycle between arthropods and vertebrates. Others, such as Long Pine Key virus (LPKV), are insect-specific. We investigated whether untranslated sequences in the genome of LPKV are critical determinants of its host restriction. A chimeric virus was created by inserting the entire 5' and 3' untranslated regions and capsid gene of LPKV into the genetic backbone of Zika virus (ZIKV). The virus replicated in mosquito cells, but not vertebrate cells. Three additional chimeras were...
- Antiviral Profiling of C-18- or C-19-Functionalized Semisynthetic Abietane Diterpenoids Mon, 15 Aug 2022 06:00:00 -0400
Viral infections affect several million patients annually. Although hundreds of viruses are known to be pathogenic, only a few can be treated in the clinic with available antiviral drugs. Naturally based pharmacotherapy may be a proper alternative for treating viral diseases. Several natural and semisynthetic abietane-type diterpenoids have shown important antiviral activities. In this study, a biological evaluation of a number of either C-18- or C-19-functionalized known semisynthetic abietanes...
