A serological survey was conducted in Uberlândia, Brazil, to find hantavirus infection in rodents, capturing 611 rodents with a higher success rate in peri-urban areas (26.3%).
Rodents in rural areas showed a higher prevalence of hantavirus antibodies, particularly the species Necromys lasiurus, which had the highest infection rate (4.6%).
The study found that factors like population density, age, and presence of scars in N. lasiurus correlated with higher antibody prevalence, indicating that horizontal transmission is key for the virus's persistence in the ecosystem.
