Hantaviruses are most commonly found in rodents and Hantavirus Syndrome is contracted through contact with the urine, saliva or faeces of rats and mice. The virus is mainly transmitted to people when they breathe in air contaminated with the virus. The virus gets into the air when rodent urine, droppings, or nesting materials are stirred up. People then breathe in this ‘mist’ and this leads to infection. It is possible that the virus may be transmitted by rodent bites, direct contact with rodent urine and faeces.
Hantavirus Syndrome is a very rare disease.
