oropouche virus transmission in the amazon river basin of peru. | seroepidemiologic studies were conducted to determine the prevalence of oropouche (oro) viral antibody, risk factors, and the incidence of infection among residents of the amazon region of peru. blood samples, as well as demographic, cultural, and medical history data, were collected from residents in a sector of the city of iquitos and in an adjacent rural and three neotropical rain forest communities. blood specimens were obtained approximately one year later from a cohort of the same study su ... | 1997 | 9080872 |
epidemiology of endemic oropouche virus transmission in upper amazonian peru. | a cross-sectional serosurvey of a rural community near iquitos, peru was conducted to determine oropouche (oro) virus antibody prevalence and risk factors for human infection. venous blood samples, and demographic, social, and risk factor data were obtained from people age five years of age and older who lived in the village of santa clara on the nanay river, a tributary of the amazon river. sera were tested for oro viral antibody by an elisa. the specificity of viral antibody reactivity was det ... | 1998 | 9840586 |
biting rates and developmental substrates for biting midges (diptera: ceratopogonidae) in iquitos, peru. | biting midges (diptera: ceratopogonidae) were collected at 16 periurban and rural sites around iquitos, peru, between 17 october 1996 and 26 may 1997. culicoides paraensis (goeldi), the principal vector of oropouche virus, was the most commonly collected species (9,086 flies) with culicoides insinuatus wirth & blanton second (7,229 flies). although both species were collected at all sampling sites (linear (distance surveyed approximately 25 km), c. paraensis dominated at northern collection site ... | 2003 | 14765657 |
changes in relative species compositions of biting midges (diptera: ceratopogonidae) and an outbreak of oropouche virus in iquitos, peru. | species compositions of culicoides paraensis (goeldi) (diptera: ceratopogonidae), the major vector of oropouche virus to humans in central and south american urban cycles, and culicoides insinuatus ortiz & leon differed along a northeast-to-southwest transect across iquitos, department of loreto, peru. the relative distributions of the species were consistent with patterns of human outbreaks along the amazon river. we resumed collection of biting midges between may 2000 and january 2004 at three ... | 2005 | 16119543 |
