Friday, June 5, 2026- Argentina is urgently widening its public health response as authorities intensify the search for hantavirus-carrying rodents across Mendoza province.
The move comes after recent human infections linked to a rare Andes strain, pushing scientists to expand field trapping and environmental sampling beyond previously monitored southern zones.
Health officials say the goal is not only to trace possible transmission routes but to identify hidden ecological hotspots where infected rodent populations may be circulating undetected.
Teams from Argentina’s national research institutes are now working alongside international experts to capture and test rodents in high-priority areas.
The focus has shifted toward Mendoza due to its ecological conditions and potential rodent reservoirs, even though confirmed local circulation of the virus has not yet been established there.
Authorities stress that early detection is critical, as hantavirus can cause severe respiratory illness with a high fatality rate and no specific cure or vaccine currently available.
The situation is driving a more aggressive surveillance strategy across multiple provinces, signaling a shift from reactive response to proactive containment.
With results from ongoing rodent testing still pending, health officials are treating the situation as time-sensitive, aiming to prevent any unnoticed spread into populated or agricultural regions.
Experts warn that rapid environmental changes and rodent movement patterns could expand risk zones, making early intervention essential for controlling future outbreaks.
