چکیده

We conducted a statewide survey of Oklahoma small mammals to test for antibodies against rodent-borne viral diseases. Four rodent species had antibody to Sin Nombre virus (SNV), the primary causative agent of hantavirus pulmonary syndrome (HPS), and two species had antibody to Whitewater Arroyo virus, an arenavirus associated with human fatalities. The rodent reservoirs for other HPScausing North American hantaviruses also occur within the state. This 13-month seroepidemiologic survey assayed 26 species of small mammals belonging to 14 genera collected from 14 locales in 8 of the 9 major physiognomic regions of Oklahoma. Of 686 captures, 5.25% were SNV-seropositive. The SNV-seropositive species were Peromyscus maniculatus, P. gossypinus, P. leucopus, and Sigmodon hispidus. Of the peromyscines, 8.4% of captures were SNV-seropositive. Four localities exhibited two or more seropositive species. We found high capture and SNV-seropositive rates for the white-footed mouse, P. leucopus: 25% of all captures, 67.7% of all peromyscine captures, and 44.4% of all seropositive individuals. P. leucopus has been associated with HPS cases caused by New York hantavirus and by Monongahela hantavirus in Pennsylvania. Health professionals and those at risk for occupational exposure should be aware that pathogenic rodent-borne viruses occur within the state. © 2001 Oklahoma Academy of Science1

Hantavirus Infection in Humans and Rodents, Northwestern Argentina

We initiated a study to elucidate the ecology and epidemiology of hantavirus infections in northern Argentina. The northwestern hantavirus pulmonary syndrome (HPS)-endemic area of Argentina comprises Salta and Jujuy Provinces. Between 1997 and 2000, 30 HPS cases were diagnosed in Jujuy Province (population 512,329). Most patients had a mild clinical course, and the death rate (13.3%) was low. W...

Hantavirus and arenavirus antibody prevalence in rodents and humans in Trentino, Northern Italy.

The spatial and temporal distribution of hantavirus and arenavirus antibody-positive wild rodents in Trentino, Italy, was studied using immunofluorescence assays (IFA) in two long-term sites trapped in 2000-2003, and six other sites trapped in 2002. The overall hantavirus seroprevalence in the bank voles, Clethrionomys glareolus (n=229) screened for Puumala virus (PUUV) antibodies was 0.4%, and...

Hantavirus and Arenavirus Antibodies in Persons with Occupational Rodent Exposure, North America

Rodents are the principal hosts of Sin Nombre virus, 4 other hantaviruses known to cause hantavirus pulmonary syndrome in North America, and the 3 North American arenaviruses. Serum samples from 757 persons who had worked with rodents in North America and handled neotomine or sigmodontine rodents were tested for antibodies against Sin Nombre virus, Whitewater Arroyo virus, Guanarito virus, and ...

Hantaviruses and Hantavirus Pulmonary Syndrome, Maranhão, Brazil

To confirm circulation of Anajatuba virus in Maranhao, Brazil, we conducted a serologic survey (immunoglobulin G ELISA) and phylogenetic studies (nucleocapsid gene sequences) of hantaviruses from wild rodents and persons with hantavirus pulmonary syndrome. This virus is transmitted by Oligoryzomys fornesi rodents and is responsible for hantavirus pulmonary syndrome in this region.

Serologic survey for hantavirus infections among wild animals in rural areas of São Paulo State, Brazil.

A serosurvey was conducted in wild animals captured close to two areas where hantavirus cardiopulmonary syndrome (HCPS) occurred in São Paulo State, Brazil. Serum samples from a total of 43 mammals were tested for antibodies reactive with Sin Nombre (SN) hantavirus using a strip immunoblot assay. RNAs from the blood clots of the positive samples were submitted to reverse transcriptase-polymeras...
