Background: Hantavirus infection is an emerging zoonosis transmitted by wild rodents. In Brazil, high case-fatality rates among humans infected with hantavirus are of serious concern to public health authorities. Appropriate preventive measures partly depend on reliable knowledge about the geographical distribution of this disease.
Methods: Incidence of hantavirus infections in Brazil (1993-2013) was analyzed. Epidemiological, socioeconomic, and demographic indicators were also used to classify cities' vulnerability to disease by means of multi-criteria decision analysis (MCDA).
Results: From 1993 to 2013, 1752 cases of hantavirus were registered in 16 Brazilian states. The highest incidence of hantavirus was observed in the states of Mato Grosso (0.57/100,000) and Santa Catarina (0.13/100,000). Based on MCDA analysis, municipalities in the southern, southeastern, and midwestern regions of Brazil can be classified as highly vulnerable. Most municipalities in northern and northeastern Brazil were classified as having low vulnerability to hantavirus cardiopulmonary syndrome.
Conclusions: Although most human infections by hantavirus registered in Brazil occurred in the southern region of the country, a greater vulnerability to hantavirus was found in the Brazilian Midwest. This result reflects the need to strengthen surveillance where the disease has thus far gone unreported.

Hantavirus Pulmonary Syndrome (HPS) is a Pan-American emerging infectious disease with a high mortality rate caused by rodent-borne viruses of the genus Orthohantavirus. In Argentina, almost half of the HPS infections occur in the northwestern endemic region. In this study, we evaluated rodent composition, abundance, and antibody prevalence in wild rodents in three subtropical sites: primary forest, secondary forest, and crop fields.

Background: Bat-borne hantaviruses have been identified worldwide but little is known about neotropical bats in the megadiverse biomes of the American continent. Although serological evidence has hinted at hantavirus circulation in Brazil, the scarce number of genomic detection represents a gap to understand viral diversity, prevalence, and ecology of bat-borne hantaviruses.
Objective: We aim to investigate and evaluate the presence and prevalence of bat-borne hantavirus in the Brazilian Atlantic Forest.

Background: Leptospirosis (LS) and hantavirus (HV) are rodent-borne diseases and share similar clinical manifestations, posing diagnostic challenges.
Methods: This retrospective study compared clinical characteristics, laboratory data, complications and outcomes of 33 LS and nine HV cases in Kaohsiung, Taiwan, from 2006 to 2021.
Results: Both LS and HV diseases had high rates of acute kidney injury (84.

Molossus molossus is a widely distributed neotropical bat species in the Americas, often found in urban areas. This study evaluated climate change effects on the potential geographic distribution of M. molossus, a natural host of zoonotic pathogens such as Orthohantavirus, in the Neotropical region.
