| [exanthematous diseases and the first epidemic of dengue to occur in manaus, amazonas state, brazil, during 1998-1999]. | in 1998, the fmt/imt-am foundation implemented the surveillance system to diagnose acute undifferentiated febrile syndromes, with the objective of active and passive surveillance in brazilian western amazonian rainforest to identify and diagnose the etiologic agents of acute fever. the diagnoses were performed using serological tests to detect igm antibodies by elisa (enzyme-linked-immunosorbent assay) cdc/opas or using commercial kits. a total of 8,557 serum samples obtained from patients with ... | 2004 | 15765597 |
| oropouche fever epidemic in northern brazil: epidemiology and molecular characterization of isolates. | oropouche fever virus is an important arbovirus associated with febrile disease that re-emerged in 2006 in several municipalities of pará state, bragantina region, amazon, brazil, 26 years after the last epidemic. | 2009 | 19117799 |
| clinical and virological descriptive study in the 2011 outbreak of dengue in the amazonas, brazil. | dengue is a vector-borne disease in the tropical and subtropical region of the world and is transmitted by the mosquito aedes aegypti. in the state of amazonas, brazil during the 2011 outbreak of dengue all the four dengue virus (denv) serotypes circulating simultaneously were observed. the aim of the study was to describe the clinical epidemiology of dengue in manaus, the capital city of the state of the amazonas, where all the four denv serotypes were co-circulating simultaneously. | 2014 | 24978469 |
| identification of oropouche orthobunyavirus in the cerebrospinal fluid of three patients in the amazonas, brazil. | oropouche fever is the second most frequent arboviral infection in brazil, surpassed only by dengue. oropouche virus (orov) causes large and explosive outbreaks of acute febrile illness in cities and villages in the amazon and central-plateau regions. cerebrospinal fluid (csf) samples from 110 meningoencephalitis patients were analyzed. the rna extracted from fluid was submitted to reverse transcription-polymerase chain reaction and sequencing to identify orov. three csf samples showed the prese ... | 0 | 22492162 |
| detection of herpesvirus, enterovirus, and arbovirus infection in patients with suspected central nervous system viral infection in the western brazilian amazon. | acute infections of the central nervous system (cns) can be caused by various pathogens. in this study, the presence of herpesviruses (hhv), enteroviruses (evs), and arboviruses were investigated in csf samples from 165 patients with suspected cns viral infection through polymerase chain reaction (pcr) and reverse transcriptase pcr. the genomes of one or more viral agents were detected in 29.7% (49/165) of the csf samples. evs were predominant (16/49; 32.6%) followed by epstein-barr virus (ebv) ... | 2014 | 24760682 |
| oropouche virus: clinical, epidemiological, and molecular aspects of a neglected orthobunyavirus. | oropouche virus (orov) is an important cause of arboviral illness in latin american countries, more specifically in the amazon region of brazil, venezuela and peru, as well as in other countries such as panama. in the past decades, the clinical, epidemiological, pathological, and molecular aspects of orov have been published and provide the basis for a better understanding of this important human pathogen. here, we describe the milestones in a comprehensive review of orov epidemiology, pathogene ... | 2017 | 28167595 |
