dengue epidemic in the state of rio grande do norte, brazil, in 1997.during 1997 a large dengue epidemic occurred in rio grande do norte, a state in north-east brazil. the co-circulation of dengue virus type 1 and dengue virus type 2 was demonstrated by virus isolation in aedes albopictus clone c6/36 cell-line and by reverse transcriptase-polymerase chain reaction (rt-pcr). igm capture enzyme-linked immunosorbent assay confirmed 52.3% of the 8105 studied cases and dengue antigen was demonstrated by immunohistochemical reaction on hepatocytes from 2 out of 5 fatal ...199910492750
seasonal variation of potential flavivirus vectors in an urban biological reserve in northeastern brazil.although yellow fever (yf) has not been reported on the eastern coast of brazil since 1942, there was a reemergence of dengue fever in brazil in 1987 due to the reintroduction of aedes aegypti (l.). to assess areas of potential risk for transmission of vector-borne diseases, a surveillance system was placed in a large atlantic forest reserve in natal, rio grande do norte, brazil, where in 2004 unexplained epizootics were reported among marmosets. the etiologic agent causing the mortality in marm ...200919960696
zika virus in brazil and the danger of infestation by aedes (stegomyia) mosquitoes.zika virus, already widely distributed in africa and asia, was recently reported in two northeastern brazilian: state of bahia and state of rio grande do norte, and one southeastern: state of são paulo. this finding adds a potentially noxious virus to a list of several other viruses that are widely transmitted by aedes (stegomyia) aegypti and aedes (stegomyia) albopictus in brazil. the pathology and epidemiology, including the distribution and vectors associated with zika virus, are reviewed. th ...201626689277
dengue virus infection of the central nervous system (cns): a case report from brazil.dengue infection that is accompanied by unusual complications has been described in brazil. we report on the presence of dengue virus in the central nervous system (cns) of a patient who died in 1998 in rio grande do norte, northeast brazil. den-2 viruses were isolated from the brain liver, and lymphnode tissue of a 67-year-old man whose signs and symptoms were those of dengue infection and a secondary immune response. a postmortem revealed nose bleeds a liver that was brownish with yellow areas ...200212118463

spatial distribution of dengue disease in municipality of mossoró, rio grande do norte, using the geographic information system.the dengue viral infection is one of the most relevant vector-borne diseases in the world. the disease can manifest in a variety of forms, from asymptomatic to a condition of dengue hemorrhagic fever (dhf). the last reported cases in brazil correspond to 80% of the cases reported in the americas, which emphasizes the magnitude of the problem. this study was conducted using geographic information system (gis) techniques, in order to evaluate the spatial distribution of the disease in the urban ar ...201324896274
