Record incidence of hantavirus disease

(Deutsches Aerzteblatt International) 2824 new cases of hantavirus disease were reported in Germany in 2012, the highest number ever in a single year. In the current issue of Deutsches Ärzteblatt International, Detlev Krüger and coauthors present the main facts about this disease.

AbstractHantaviruses (orderBunyavirales, familyHantaviridae), known as important zoonotic human pathogens, possess the capacity to exchange genome segments via genetic reassortment due to their tri-segmented genome. Although not as frequent as in the arthropod-borne bunyaviruses, reports indicating reassortment events in the evolution of hantaviruses have been recently accumulating. The intra- and inter-lineage reassortment between closely related variants has been repeatedly reported for several hantaviruses including the rodent-borne human pathogens such as Sin Nombre virus, Puumala virus, Dobrava-Belgrade virus, or Hant...

AbstractHantavirus cardiopulmonary syndrome (HPS) has gained importance in Latin America as an emerging disease, with reports of about 4000 HPS cases; however, this is probably an underestimate because of limited surveillance programs and diagnostic tools to confirm HPS. In order to address this issue and develop better serosurveillance capability, we evaluated three recombinant peptides from the Necocl í virus (NECV) nucleocapsid in antibody-capture ELISA. We cloned and expressed antigens representing the whole NECV nucleocapsid protein (NECV-rN), the immunodominant domain (NECV-rN100), and a serospecific domain (N...

This study aimed to map the occurrence of N. lasiurus within the Atlantic Forest of Rio de Janeiro state and discuss the potential role of the species as a reservoir of the Araraquara hantavirus in these areas. The study was based on a comprehensive literature search and four expeditions for the collection of specimens in the state of Rio de Janeiro. The data were used to predict the distribution of N. lasiurus, confirm the distribution of the species in the state, and detect the rates of hantavirus infection in these rodents. Necromys lasiurus has been recorded at 16 localities in 10 municipalities of Rio de Janeiro state...

AbstractGreen spaces in urban areas can play a key role in protecting wildlife. However, the presence of wildlife in urban areas can lead to human health risks. Although the presence of the rodent speciesOligoryzomys flavescens (hantavirus reservoir) has been recorded in cities of Argentina, its population dynamics in this type of habitat is still unknown. Here, we evaluated: (1) long-term spatial and temporal patterns ofO. flavescens abundance and how these patterns were influenced by weather factors and (2) the seroprevalence of hantavirus and the identity of the viral lineage circulating in the population that inhabits ...

We described a serosurvey for orthohantaviruses circulation in an apparently healthy human population and small mammals from rural areas in Central Minas Gerais State, Brazil. A total of 240 individuals and 50 small mammals (26 rodents belonging to 10 different species and 24 marsupials from 4 different species) were sampled during 2012 –2013. The seroprevalence rates of IgG/IgM antibodies in humans were 7.1 and 1.6%, respectively. Only one rodent, anOligoryzomys nigripes captured in peridomestic area, tested positive for IgG antibodies and viral RNA. Our findings suggest a silent circulation of orthohantaviruses in ...

Background: Hantavirus is responsible for potentially deadly emerging disease in humans and have rodents as natural reservoirs. The human disease may be mainly exhibited as haemorrhagic fever with renal syndrome, which is prevalent in Europe and Asia, or cardiopulmonary syndrome, with significant morbidity and mortality and which is prevalent in America. Despite being endemic in the Amazon region, there are few reported cases and little epidemiological data.

Background: Introduction: Hantavirus pulmonary syndrome (HPS) is an emerging zoonotic disease in our country, transmitted to humans by infected rodents. The endemic areas are 4: Northwest, Central, Northeast and Southwest area. Infection rates in wild reservoirs are variable, with seasonal fluctuations. In recent years there has been an increase in cases attributed to biological factors due to changes in the environment.

Background: Hantaviruses, like other members of the Bunyaviridae family, are emerging viruses that are able to cause hemorrhagic fevers. They are the etiological agents of 2 syndromes geographically distributed: hemorrhagic fever with renal syndrome (HFRS) in Europe and Asia, and hantavirus cardiopulmonary syndrome (HCPS) in America. There are 52 hantavirus species. Research on them, has not been equal. So far, there is no comprehensive bibliometric studies assessing advances in their research.
