At least three hantavirus genospecies are circulating among wild rodents in Europe: Puumala, Dobrava and Tula, the two first being of clinical significance for humans as possible causative agents of haemorrhagic fever with renal syndrome. As many as 710 adult individuals randomly selected from 12 regions of the Czech Republic were screened for the presence of antibodies against hantaviruses. Commercial sets with Hantaan and Puumala antigens were used for this purpose. Five subjects showed IgG reactivity to Hantaan-like virus (Dobrava) and one subject tested positive for both IgG and IgM antibodies. Two other subjects showed IgM reactivity alone. This means that as many as seven (1.0%) subjects showed reactivity to Hantaan antigen. Eight subjects showed IgG reactivity to Puumala antigen, none of them being IgM positive. Two other subjects were IgM positive only. Altogether ten (1.4%) subjects were reactive to Puumala antigen. Three subjects showed reactivity to both of the antigens tested.

In 2021, a large outbreak of hantavirus disease (HAVID) in Croatia with 334 notified cases coincided with a COVID-19 wave and included patients from areas previously not considered endemic, challenging HAVID recognition and patient management. We analysed clinical and epidemiological data on all 254 patients with HAVID treated in the Clinical Hospital Center Rijeka (CHC Rijeka) between February and November 2021. Most patients (n = 246; 96.

Orthohantaviruses are emerging zoonotic viruses that can infect humans via the respiratory tract. There is an unmet need for an in vivo model to study infection of different orthohantaviruses in physiologically relevant tissue and to assess the efficacy of novel pan-orthohantavirus countermeasures. Here, we describe the use of a human lung xenograft mouse model to study the permissiveness for different orthohantavirus species and to assess its utility for preclinical testing of therapeutics.

Wild rodents serve as crucial reservoirs for zoonotic viruses. Anthropogenic and environmental disruptions, particularly those induced by mining activities, can destabilize rodent populations and facilitate the emergence of viral agents. In the Canaã dos Carajás and Curionópolis regions of Brazil, significant environmental changes have occurred due to mining expansion, potentially creating conditions conducive to the emergence of rodent-associated viral diseases.

Introduction: Acute undifferentiated febrile illnesses are fevers lasting less than fourteen days without an evident focus of infection on the initial physical examination or with inconclusive laboratory tests.
Objective: Carry out epidemiological surveillance of the etiology of acute undifferentiated febrile syndrome in the Meta department.
Methods: A descriptive, prospective cross-sectional study was carried out between February 2021 and June 2023 in a first-level hospital in the department of Meta, Colombia.

Hantaviruses are zoonotic pathogens associated with severe human diseases such as hemorrhagic fever with renal syndrome and hantavirus pulmonary syndrome. Despite the extensive study of rodent-borne hantaviruses, research on bat-associated hantaviruses remains limited. This study aimed to investigate the seroprevalence and cross-reactivity of neotropical bat samples with rodent- and bat-associated recombinant hantavirus nucleoproteins (rNPs) to improve hantavirus surveillance in the Brazilian Atlantic Forest.
