Scientists from Buenos Aires' leading virology centre and local specialists are inspecting rodent traps in Ushuaia to trace a deadly hantavirus outbreak.
The operation is critical because the Andes strain is the only hantavirus known to spread between people [1]. Identifying the presence of this specific strain in local rodent populations allows health officials to understand the scope of the transmission risk in the region.
The team is currently on the second day of the hunt on the southern island of Tierra del Fuego. This follows the initial deployment of traps that began on Monday [2]. The researchers are focusing their efforts in Ushuaia to determine if local animals are carrying the virus.
By capturing and testing these rodents, the virologists aim to map the geographical spread of the virus. The Andes strain presents a unique public health challenge compared to other hantaviruses, which typically only jump from animals to humans. The ability for this specific strain to move from person to person increases the potential for wider community outbreaks.
The search is part of a broader effort to contain the current deadly outbreak. Local specialists are working alongside the Buenos Aires team to ensure the traps are placed in high-activity rodent areas across the island's rugged terrain.
As the operation continues, the data gathered from these traps will inform the government's response to the outbreak. The findings will help determine if current containment strategies are sufficient or if more aggressive public health interventions are required to stop the spread of the Andes strain.
“The Andes strain is the only hantavirus known to spread between people.”
The focus on the Andes strain is significant because its capacity for human-to-human transmission removes the animal vector as the sole point of infection. This transforms the outbreak from a localized zoonotic event into a potential epidemic, necessitating more stringent quarantine and contact-tracing protocols than standard hantavirus responses.
