While hantavirus is in the news of late because of severe illness on a cruise ship, it's really a greater risk to campers and hikers. The disease is caused almost exclusively from contact with the waste products, urine and feces, of rodents. Infection can come from particles entering wounds, or by breathing aerosols or dust.
Most cases in the US are transmitted by deer mice, but most rodents carry some strain of hantavirus. Although the death rate is high from the disease the CDC has tracked only about 30 cases per year for the past 30 years. Voles, shrews, bats, pigs, and cattle have all been noted to sometimes carry a hantavirus. In truth, the risk of contacting the virus is high, but simple cleanliness reduces the risk significantly.
94% of cases in the US have occurred west of the Mississippi.
Campers often use huts, shelters, outhouses, and register boxes where evidence of rodent occupation is obvious. There are simple things you can do to reduce your chances of contracting hantavirus:
• try to sleep elsewhere if you encounter mouse droppings or nests
• store your food in rodent-proof containers
• wear gloves and mask if cleaning areas where you find droppings or nests, and disinfect the areas.
