Hantavirus is a growing topic of interest following the recently reported outbreak on a cruise ship in the Atlantic. While there are no clinical guidelines for the prevention of hantavirus or the treatment of hantavirus pulmonary syndrome, there are numerous recently published articles regarding the virus, including risk assessments and the latest in research and development. Consistent engagement with current medical literature enables clinicians to apply the latest research into clinical practice. This approach enhances patient outcomes by facilitating more effective and individualized care.

Today, we’re showcasing some of the latest hantavirus-related articles published recently across medical journals followed by some insights from the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO). Some article descriptions were edited for clarity and brevity.

High-Resolution in Situ Structures of Hantavirus Glycoprotein Tetramers

  • Cell, March 2026
  • Description: New World hantaviruses cause severe infections in humans. Previous structural studies have advanced our understanding of hantavirus glycoprotein architecture, however, the lack of high-resolution structures of the glycoprotein tetramer and its lattice organization has limited mechanistic insights into viral assembly and entry. Here, we leveraged a virus-like particle (VLP) system to establish a cryo-electron microscopy workflow for lattice-forming viral glycoproteins.

Human Hantavirus Infections in Hungary (2018–2025): Epidemiology, Molecular Detection Across Clinical Sample Types, and Phylogenetic Analysis

  • Viruses, March 2026
  • Description: Hantaviruses are globally distributed, rodent-borne zoonotic pathogens. In Hungary, Dobrava-Belgrade virus (DOBV) and Puumala virus (PUUV) are circulating, causing hemorrhagic fever with renal syndrome and nephropathia epidemica, respectively.

A Pan-European Assessment of Multi-Sector Drivers of Human Hantavirus Risk: Climate Biodiversity, and Socio-Economic Factors as Key Determinants

  • Environmental Research, March 2026
  • Description: The landscape of emerging zoonoses is being rapidly reshaped by concurrent climate change, environmental transformation, and biodiversity loss. These pressures can alter host populations, pathogen dynamics, and human exposure. Yet, continental-scale evidence linking multi-sector drivers to human infection risk for specific rodent-borne diseases remains limited, particularly for hantavirus. To untangle these influences, we assembled the most high-resolution European hantavirus infection dataset to date (2011–2021), combining large datasets on climatic, environmental, biodiversity, and socio-economic aspects to identify the main drivers of human hantavirus transmission.

Specific and Versatile Monoclonal Antibodies for Hantavirus Research

  • mSphere, December 2025
  • Description: Rodent-borne hantaviruses pose a continual public health threat to humans through zoonotic transmission, with case fatality rates of up to 50% in some cases. Human infections can lead to hemorrhagic fever with renal syndrome (HFRS) or hantavirus cardiopulmonary syndrome depending on the viral species. Despite the morbidity and mortality associated with this family of viruses, no anti-viral therapeutics or vaccines are available to treat and prevent hantavirus disease.

Epidemiologic and Environmental Investigations of Reported Hantavirus Cases Inform Exposure Risk in California, 1993–2020

  • The American Journal of Tropical Medicine and Hygiene, October 2025
  • Description: The objectives of this paper were to summarize the key findings from investigations of reported hantavirus cases from 1993 to 2020 and demonstrate which types of information (epidemiologic, environmental, or molecular SNV testing) were most valuable to identify likely exposure locations. Information from this summary may guide future public health response to hantavirus cases.

Hantavirus is Associated with Open Developed Areas and Arid Climates, Highlighting Increased Risk in Western United States

  • Transboundary and Emerging Diseases, October 2025
  • Description: Here, we use ecological niche models and human cases of HPS in the U.S. from 1993 to 2022 to assess hantavirus risk using four socioeconomic variables, 17 land use variables, one variable of rodent richness, and seven climate variables to determine both the geographical locations of highest exposure risk and leading environmental predictors.

Insights from the CDC and WHO

While there are no clinical practice guidelines on hantavirus, the CDC and the WHO have a few recommendations regarding hantavirus.

The CDC states, in a 2024 clinician brief, that early symptoms of hantavirus pulmonary syndrome may resemble other respiratory illnesses, and providers should test patients for hantavirus if patients have compatible symptoms and have experienced recent contact with rodents. The CDC states that rodent infestation in and around dwellings is the primary risk for hantavirus exposure; this includes being bitten by infected rodents, eating food contaminated with hantavirus, breathing in hantavirus-contaminated air when clearing out rodents, and a person touching contaminated objects and then touching their nose or mouth.

A 2026 WHO fact sheet on hantavirus states that, in the Americas, hantavirus can lead to a severe respiratory illness called hantavirus cardiopulmonary syndrome, with a case fatality of up to 50%. Listed symptoms include nausea, vomiting, abdominal pain, muscle aches, headache, and fever. Early supportive medical care is key, the WHO fact sheet explains, accompanied by close clinical monitoring and management of complications.
