Hantavirus Pulmonary Syndrome
Hantaviruses are a group of viruses that can cause severe illness in humans. There are several different types of hantaviruses found around the world, and each can cause a different disease. The two most common diseases caused by a hantavirus infection are hantavirus pulmonary (lung) syndrome (found in North and South America) and haemorrhagic fever with renal (kidney) syndrome (found mainly in Europe and Asia).
The key to disease prevention is preventing rodent infestations and properly cleaning and disinfecting areas contaminated by rodent droppings. Keep your home, workplace, cottage, or campsite rodent-free. All rodent droppings are potentially harmful. See a healthcare provider immediately if you have had contact with rodents or their droppings and urine and are showing some or all of the symptoms. Be sure to mention that you have had contact with rodents or their droppings or urine.
