Serological survey of hantavirus in rodents in Uberlândia, Minas Gerais, Brazil
We conducted a serological survey to determine the presence of hantavirus infection in rodents in Uberlândia, Minas Gerais as well as to identify and characterize associated factors. Rodents were captured using Sherman live-capture traps set in rural and peri-urban environments. A total of 611 roden...
