Argentine authorities are intensifying efforts to identify the origin of a hantavirus outbreak that occurred on a recent cruise ship departure from Ushuaia. The investigative team, equipped with protective gear, embarked on a rat-trapping mission in the forests near Ushuaia to assess potential hantavirus presence in previously unaffected areas.
Inspectors meticulously examined 150 traps, collecting deceased rodents and transporting them to a temporary laboratory for further analysis. This fieldwork initiative is part of a broader investigation into the outbreak that affected passengers on the MV Hondius, claiming three lives and causing illness among several individuals, including a Canadian.
The Malbrán Institute, a renowned infectious disease research center in Argentina, leads the investigation and plans to conduct tests on the trapped rodents in their Buenos Aires laboratory. The process may take up to a month, with authorities refraining from disclosing specific details at this stage.
Following a directive from the Argentine Health Ministry, the investigative team will continue their operations in Ushuaia for the next few days. The cruise ship’s departure point, known for its Antarctic connections, has never reported cases of hantavirus prior to this incident.
Despite assertions from health officials that Tierra del Fuego is not the outbreak source, ongoing research aims to determine if the hantavirus is present in the region. The investigation focuses on areas where the long-tailed pygmy rice rat subspecies, a potential carrier of the virus, is prevalent, as scientists explore the possibility of local transmission.
In light of rising hantavirus cases in Argentina, attributed to environmental changes and human activities, health authorities emphasize the importance of this investigation in understanding disease dynamics amid changing climatic conditions. The study’s scope includes assessing the hantavirus risk in Tierra del Fuego and implementing preventive measures to safeguard public health.
