1. 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

2. Reconstrução ligamentar da membrana interóssea do antebraço, no tratamento da instabilidade da articulação radioulnar distal
RESUMO: As infecções por pestivírus são importantes nas indústrias pecuárias, com infecções em bovinos, ovinos e suínos. O gênero Pestivirus da família Flaviviridae inclui quatro espécies reconhecidas: vírus da diarreia viral bovina 1 (BVDV-1), vírus da diarreia viral bovina 2 (BVDV-2), vírus da doença de fronteira (VDF) e vírus da peste su�

4. 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

5. 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

6. 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

7. Zika virus congenital syndrome: experimental models and clinical aspects
Abstract Viral infections have long been the cause of severe diseases to humans, increasing morbidity and mortality rates worldwide, either in rich or poor countries. Yellow fever virus, H1N1 virus, HIV, dengue virus, hepatitis B and C are well known threats to human health, being responsible for many million deaths annually, associated to a huge economic an

8. Enveloped and non-enveloped viral-like particles in Trypanosoma cruzi epimastigotes
ABSTRACT Electron microscopy is routinely used to identify viral infections in protozoan parasites. These viruses have been described as non-enveloped and icosahedral structures with a diameter of 30-60 nm. Most of them are classified within the non-segmented dsRNA Totiviridae family. We observed virus-like particles (VLPs) through transmission electron micr

9. Mosquito-transmitted viruses - the great Brazilian challenge
ABSTRACT Arboviruses pose a serious threat to public health worldwide, overloading the healthcare system and causing economic losses. These viruses form a very diverse group, and in Brazil, arboviruses belonging to the families Flaviviridae and Togaviridae are predominant. Unfortunately, the number of arboviruses increases in proportion with factors such as

10. One year after the Zika virus outbreak in Brazil: from hypotheses to evidence
Abstract Zika virusis an arbovirus of the Flaviviridae family with two major strains, an Asian and an African strain. The main vectors involved in the transmission of Zika virus are the Aedes aegypti and Aedes albopictus mosquitoes. Despite its identification, discovered in 1947 in the Zika forest in Uganda, only isolated and sporadic occurrences of human in

11. Overview of Zika virus (ZIKV) infection in regards to the Brazilian epidemic
Zika virus (ZIKV), a mosquito-borne flavivirus, belongs to the Flaviviridae family, genus Flavivirus. ZIKV was initially isolated in 1947 from a sentinel monkey in the Zika forest, Uganda. Little clinical importance was attributed to ZIKV, once only few symptomatic cases were reported in some African and Southeast Asiatic countries. This situation changed in

12. Hanseníase boderline tuberculóide e reação hansênica do tipo 1 em paciente com hepatite C durante tratamento com interferon e ribavirina
A hepatite C é uma doença inflamatória fígado causada por um vírus RNA de fita simples, pertencente ao gênero Hepacivirus e à família Flaviviridae, denominado de vírus da hepatite C. Após infecção inicial 70 a 85% dos pacientes infectados evoluem para hepatite C crônica, com fibrose progressiva. Além das alterações hepáticas específicas, v�
