You're gonna die b!tch:
Hantavirus is a rare, incurable viral disease transmitted by long-tailed wild mice. It is present throughout the Americas (though not in the far south of Patagonia) and produces haemorrhagic fever and severe respiratory problems caused by the accumulation of liquid in the lungs. Initial symptoms are similar to influenza - with fever, headache, stomachache and muscle pain - and the fatality rate is around fifty percent. The virus is present in the excrement, urine and saliva of the mouse and is transmitted to humans through breathing in contaminated air, consuming contaminated food or water, or by being bitten by or handling a virus-bearing mouse. It cannot survive sunlight, detergent or disinfectant and the best way to avoid contamination is by being scrupulously clean when camping, particularly in rural areas. Recommended precautions are using tents with a proper floor, good fastenings and no holes; keeping food in sealed containers and out of reach of mice (hanging a knotted carrier bag from a tree is a standard precaution) and cleaning up properly after eating. If staying in a cabaña which looks as though it hasn't been used for a while, let the place ventilate for a good thirty minutes before checking (while covering your mouth and nose with a handkerchief) for signs of mouse excrement. If any is found, all surfaces should be disinfected then swept and aired. Despite the severity of hantavirus, you should not be unduly worried about the disease. In the unlikely case that there is an outbreak in the area you are visiting you will be well-informed by the local authorities of the virus's presence.
