Virus isolation data improve host predictions for New World rodent orthohantaviruses.

J Anim Ecol 2022 Mar 31. Epub 2022 Mar 31.

Department of Biology, University of Oklahoma, Norman, OK, USA.

Identifying reservoir host species is crucial for understanding the ecology of multi-host pathogens and predicting risks of pathogen spillover from wildlife to people. Predictive models are increasingly used for identifying ecological traits and prioritizing surveillance of likely zoonotic reservoirs, but these often employ different types of evidence for establishing host associations. Comparisons between models with different infection evidence are necessary to guide inferences about the trait profiles of likely hosts and identify which hosts and geographical regions are likely sources of spillover.

Puerto Montt Hospital, San Sebastian University, Puerto Montt, Chile.

Hantaviruses are tri-segmented lipid-enveloped RNA viruses belonging to the family. Human infection corresponds to a zoonosis associated with two different clinical syndromes: hemorrhagic fever with renal syndrome that occurs in Asia and Europe and hantavirus cardiopulmonary syndrome (HCPS) that occurs in the North America, Central America and South America. The major pathogenic mechanisms in HCPS include (1) direct microvascular endothelial injury leading to increased capillary permeability and the development of noncardiogenic pulmonary edema and acute respiratory distress syndrome, and (2) exaggerated host immune response leading to secondary organ damage.

Hanta hemorrhagic fever with renal syndrome: A pathology in whose diagnosis kidney biopsy plays a major role (Review).

Exp Ther Med 2021 Sep 12;22(3):984. Epub 2021 Jul 12.

Department of Nephrology, 'Fundeni' Clinical Institute, 022328 Bucharest, Romania.

Hantavirus infection belongs to a group of zoonoses rare in the Balkan Peninsula, causing two major syndromes, depending on the viral serotype involved: Hemorrhagic fever with renal syndrome (HFRS) also known as endemic nephropathy and cardiopulmonary syndrome (CPS). Because there is no specific treatment or vaccine for this condition approved in the USA or Europe, the key to minimizing the risk of adverse progression to chronic kidney disease, secondary hypertension or even death is primarily the recognition and early diagnosis of this condition with prompt therapeutic intervention. The aim of this study was to review the literature data on the epidemiology, pathogenesis and management of this disease and to identify several aspects related to the difficulties encountered in diagnosing this pathology, taking into consideration that the disease is not endemic in this geographical area.
