Argentine scientists are conducting a field investigation in and around Ushuaia to determine whether hantavirus is present in local rodent populations. According to reports, researchers lay the first traps and begin collecting rodents in the woods near the port city. The work is connected to earlier concerns following the departure of the MV Hondius cruise ship, which had reportedly been affected by cases of hantavirus before sailing. Multiple outlets describe the effort as focused on identifying potential rodent carriers in the area from which the ship set sail. The scientists’ activities include trapping and gathering rodents for subsequent testing to assess whether hantavirus is circulating in the region. One report notes that researchers observed the initial trapping on Monday, while another describes the start of broader rodent collection on Tuesday. Overall, the articles present the investigation as an early-stage attempt to check the local wildlife reservoir and clarify whether the virus is present in Ushuaia’s environment, using trapped specimens for laboratory analysis.
