SummaryBackgroundHantaviruses in Europe and Asia cause haemorrhagic fever with renal syndrome and epidemic nephritis (mortality rate <1–15%). New strains of Hantaviruses cause Hantavirus pulmonary syndrome (HPS) from Canada to South America. Andes virus mortality rate is about 30% in Chile.MethodClinical charts of 54 patients were reviewed.ResultsInhalation of aerosolized urine, faeces or saliva of rodents is the principal cause of infection. The incubation period is between 8 and 43 days. The main prodromal symptoms are: myalgias, fever, fatigue, gastrointestinal disorders, dyspnoea, petechiae and coughing. After the 4th day pulmonary oedema, hypotension and renal failure appear. Haemorrhagic disorders may occur. The first laboratory tests presenting alterations are: haemoconcentration, leukocytosis, low platelet count <150 μ/L, and presence of immunoblasts. The treatment is supportive: mechanical ventilation, vasopressor drugs, haemofiltration or haemodialysis, and extracorporeal membrane oxygenation. There is no specific treatment for HPS. Preventive measures must be empathised.ConclusionThe principal risk factors for tourists are: accommodation in abandoned or closed up facilities; failure to use indicated pathways when walking in forests; camping outside recommended areas; drinking water from natural sources and fishing in risk areas. The risk of infection for foreign tourists in Chile is low.
