Hantaviruses cause the acute zoonotic diseases hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Infected patients show strong systemic inflammation and immune cell activation. NK cells are highly activated in HFRS, suggesting that also other innate lymphoid cells (ILCs) might be responding to infection.

Article Synopsis
  • The North American Deermouse is a common mammal linked to Hantavirus Pulmonary Syndrome (HPS), posing a public health risk due to its role as a virus host.
  • Recent studies reveal that the Deermouse is actually a complex of multiple species, which complicates the interpretation of longstanding hantavirus monitoring data.
  • A systematic review of 46 studies from 2000 to 2022 shows that virus detection is mainly concentrated in the Western U.S. and Mexico, highlighting geographical gaps and the need to consider the new taxonomic classifications in hantavirus research.

Critical care management of hantavirus cardiopulmonary syndrome. A narrative review.

J Crit Care

December 2024

Departamento de Medicina Intensiva, Facultad de Medicina, Pontificia Universidad Católica de Chile, Santiago, Chile. Electronic address:

Hantaviruses, members of the Bunyaviridae family, can cause two patterns of disease in humans, hantavirus hemorrhagic fever with renal syndrome (HFRS) and cardiopulmonary syndrome (HCPS), being the latter hegemonic on the American continent. Andesvirus is one of the strains that can cause HCPS and is endemic in Chile. Its transmission occurs through direct or indirect contact with infected rodents' urine, saliva, or feces and inhalation of aerosol particles containing the virus.

Article Synopsis
  • Orthohantaviruses are significant public health threats, causing various diseases like hemorrhagic fever and hantavirus pulmonary syndrome, so monitoring wild rodents for these viruses is crucial for outbreak preparedness.
  • Researchers conducted a study from 2015 to 2017 in Southern Anatolia but found no evidence of orthohantavirus infections among the trapped rodents.
  • The study suggests that orthohantavirus presence may be influenced by climatic conditions, particularly precipitation and temperature, and emphasizes the need for further research on rodent surveillance in different regions.
