1. Quanto tempo após o parto as puérperas podem ser vacinadas contra a febre amarela?
A vacina contra a febre amarela não está indicada para as mulheres que estejam amamentando crianças com até 6 meses de idade, independentemente do estado vacinal, devendo ser adiada até a criança completar 6 meses de vida. Na impossibilidade de adiar a vacinação, como em situações de emergência epidemiológica, vigência de surtos, epidemias ou

2. A emergência da dengue como desafio virológico: de doença-fantasma à endemia “de estimação”, 1986-1987
Resumo O artigo analisa como a dengue se apresentou como desafio virológico na década de 1980. O objetivo é entender o papel dos estudos virológicos na compreensão da doença e a construção de uma expertise em arboviroses. Embora surtos da doença já tivessem sido relatados ao longo do século XX, a dengue era pouco conhecida nas Américas até a epi

3. Zika virus RNA detection in blood donors in São Paulo, Brazil
ABSTRACT Introduction: The Zika Virus (ZIKV) is a single-stranded RNA genome virus, belonging to the family Flaviviridae, genus Flavivirus. Outbreaks around the world have demonstrated that the presence of asymptomatic viremic blood donors provides an increase in the risk of transfusion transmission (TT) and nucleic acid test (NAT) screening has been propos

4. PREPARATION OF HYBRID POLYMERS AND USE AS CONTROLLED RELEASE DELIVERY VEHICLE FOR VOLATILE REPELLENT TO CONTROL Aedes aegypti
The Zika virus is a flavivirus spread by the Aedes aegypti mosquito, which also transmits dengue and chikungunya. Current forms of control include elimination of mosquito breeding sites, use of insecticides, repellents and other means. The present study developed new adsorbent materials based on silica and biomaterials capable of releasing an Aedes aegypti m

5. Molecular survey of flaviviruses and orthobunyaviruses in Amblyomma spp. ticks collected in Minas Gerais, Brazil
Resumo Alterações ambientais causadas pelo homem têm levado à emergência de doenças transmitidas por vetores no mundo. Carrapatos são vetores conhecidos de vários patógenos de importância médica e veterinária, tendo sido reportado nas últimas décadas um grande número de enfermidades virais emergentes transmitidas por eles (vírus da Febre Hemo

6. Previous dengue or Zika virus exposure can drive to infection enhancement or neutralisation of other flaviviruses
BACKGROUND Dengue virus (DENV) has circulated in Brazil for over 30 years. During this time, one serotype has cyclically replaced the other, until recently, when all four distinct serotypes began to circulate together. Persistent circulation of DENV for long time periods makes sequential infections throughout a person’s life possible. After primary DENV

7. Comparative assessment of the replication efficiency of dengue, yellow fever, and chikungunya arboviruses in some insect and mammalian cell lines
Abstract INTRODUCTION: Insect cell cultures play an essential role in understanding arboviral replication. However, the replicative efficiency of some of these viruses such as dengue (DENV), yellow fever (YFV), and chikungunya (CHIKV) in a new cellular substrate (Lulo) and in the other two recognized cell lines has not been comparatively assessed. METHODS:

8. West Nile virus infections are here! Are we prepared to face another flavivirus epidemic?
Abstract Emerging arthropod-borne viruses (arboviruses), such as chikungunya and Zika viruses, are a major threat to public health in countries like Brazil where biodiversity is high and medical care is sometimes precarious. West Nile fever is a disease caused by the West Nile Virus (WNV), an RNA virus belonging to the Flaviviridae family. It is transmitted

9. Entomological and virological surveillance for dengue virus in churches in Merida, Mexico
ABSTRACT This study was designed to assess whether churches in endemic dengue districts in Merida, Mexico provide suitable breeding habitats for mosquitoes and are potential sites for dengue virus (DENV) transmission. Churches were inspected for immature and adult mosquitoes once every week from November 2015 to October 2016. A total of 10,997 immatures of f

10. Imported case of Dengue virus 3 genotype I in Rio de Janeiro state, Brazil
The dengue virus (DENV), of the genus Flavivirus (Flaviviridae), has four antigenically distinct serotypes, of which DENV-3 is classified into five genotypes. Here, we describe the detection of DENV-3 genotype I in sera of a Brazilian patient travelling from Singapore to Rio de Janeiro, Brazil, by using multiplex real-time RT-PCR, DNA sequencing of the whole

12. Prevalence of Guillain-Barré syndrome among Zika virus infected cases: a systematic review and meta-analysis
ABSTRACT Zika virus (ZIKV) is an emergent flavivirus transmitted mainly through Aedes spp. mosquitoes that is posing challenge to healthcare services in countries experiencing an outbreak. Usually ZIKV infection is mild, but in some cases it has been reported to progress into neurological diseases such as microcephaly in infants and Guillain-Barré syndrome
