| absence of interhuman transmission of hantavirus pulmonary syndrome in minas gerais, brazil: evidence from a serological survey. | | 1999 | 10585829 |
| hantavirus pulmonary syndrome in uberaba, minas gerais, brazil. | this report describes the epidemiological and clinical-evolutive characteristics of eight patients with hantavirus pulmonary syndrome (hps) in uberaba, minas gerais, brazil. a positive history of contact with rodents was present in 100% of the cases. the time between the onset of symptoms and hospital care was, on average, 3.6 days. all patients showed clinical and laboratory findings suggestive of hps. elevated urea and creatinine levels were observed in 6 (75%) cases, po2 was < 60 mmhg in 100% ... | 2002 | 12386696 |
| [hantavirus cardiopulmonary syndrome in the triângulo mineiro and alto paranaíba regions, state of minas gerais, 1998-2005: clinical-epidemiological aspects of 23 cases]. | the epidemiological, clinical, laboratory and treatment findings from 23 cases of hantavirus cardiopulmonary syndrome were analyzed. these cases were identified either serologically or immunohistochemically in hospitals in the municipality of uberlândia, state of minas gerais. fever (100%), dyspnea (100%) and myalgia (78%) were the symptoms most frequently observed in this sample. the most prevalent physical signs were hypotension (65%) and tachycardia (65%). the most common laboratory findings ... | 2007 | 17653464 |
| barn owl (tyto alba) predation on small mammals and its role in the control of hantavirus natural reservoirs in a periurban area in southeastern brazil. | the aim of this study was to inventory the species of small mammals in uberlândia, minas gerais, brazil, based on regurgitated pellets of the barn owl and to compare the frequency of rodent species in the diet and in the environment. since in the region there is a high incidence of hantavirus infection, we also evaluate the importance of the barn owl in the control of rodents that transmit the hantavirus. data on richness and relative abundance of rodents in the municipality were provided by the ... | 2008 | 19197490 |
| cross-sectional survey of hantavirus infection, brazil. | a cross-sectional serosurvey was conducted to assess the proportion of persons exposed to hantaviruses in a virus-endemic area of the state of minas gerais, brazil. findings of this study suggested the presence of > or =1 hantaviruses circulating in this region causing hantavirus pulmonary syndrome, mild disease, or asymptomatic infection. | 2009 | 19961680 |
| hantavirus pulmonary syndrome and rodent reservoirs in the savanna-like biome of brazil's southeastern region. | this paper describes the diversity of rodent fauna in an area endemic for hantavirus cardiopulmonary syndrome (hcps) in brazil, the population dynamics and the relationship of rodents with hantavirus in the cerrado (savanna-like) biome. additionally, an analysis is made of the partial s segment sequences of the hantaviruses obtained from serologically confirmed human hcps cases and from rodent specimens. rodents were collected during four campaigns. human serum samples were collected from suspec ... | 2016 | 26541807 |
| co-circulation in a single biome of the juquitiba and araraquara hantavirus detected in human sera in a sub-tropical region of brazil. | hantaviruses is an emerging infectious disease. although hcps has been reported in several regions of brazil, more cases of hcps have recently been reported in minas gerais than in any other state. in 2009, we analyzed 27 samples presenting antibodies against hantaviruses. these samples originated from 688 symptomatic patients, as determined based on the hemorrhagic fever protocol. a subsequent sybr green-based real-time rt-pcr demonstrated the presence of the virus in 22 of the samples. among t ... | 2015 | 25678450 |
| serological survey of hantavirus in rodents in uberlândia, minas gerais, brazil. | we conducted a serological survey to determine the presence of hantavirus infection in rodents in uberlândia, minas gerais as well as to identify and characterize associated factors. rodents were captured using sherman live-capture traps set in rural and peri-urban environments. a total of 611 rodents were captured. there was a higher trap success in peri-urban areas (26.3%) and a higher prevalence of antibodies among rodents captured in rural areas (2.9%). necromys lasiurus was the most common ... | 2013 | 23740018 |
| could hantavirus circulation superpose areas of highly endemic vaccinia virus outbreaks? a retrospective seroepidemiological study in state of minas gerais. | hantavirus infections have been described in several regions in brazil through seroepidemiological studies. usually, populations are associated with rural and wild environment mainly due to close contact to species of sigmodontinae rodents, considered hantavirus reservoirs. | 2015 | 25626659 |
