Does hantavirus only occur in ships? Are there moreexamples in say buidlings with poor pest control

Output

No, hantavirus is not specific to ships at all. Ships are just one environment where it can occur.

Hantavirus transmission happens wherever infected rodents (primarily deer mice, white-footed mice, and rats) are present and their droppings, urine, or nesting material become disturbed and aerosolized.

Common settings where outbreaks have occurred:

• Rural cabins and vacation homes — closed up over winter, mice move in, people stir up dried droppings when reopening
• Barns and outbuildings — classic agricultural exposure
• Construction sites — disturbing rodent-infested spaces
• Warehouses and storage facilities — poor pest control, undisturbed areas
• Apartments and housing — particularly basements and crawl spaces in older buildings with poor maintenance
• Campsites — sleeping on ground, rodents in tents or gear

Notable outbreak examples:

• The 1993 Four Corners outbreak in the US Southwest (Navajo Nation area) — deer mice, no ships involved
• Yosemite National Park 2012 — cabins with poor rodent sealing, 10 cases, 3 deaths
• Chile and Argentina have recurring outbreaks in rural housing

The key risk factor is disturbing enclosed, poorly ventilated spaces where rodents have been active — sweeping or vacuuming dried droppings is particularly dangerous. Ships fit that profile, but so does any neglected building.

In Canada, hantavirus (Seoul virus and Sin Nombre virus strains) is present, primarily in prairie provinces through deer mice.
