The common denominators are 1) the possible emergence of a disease with general bleedings – often leading to death; 2) the potential risk to close contacts
Hantaviruses are rodent-borne viruses. They may cause severe diseases with potential risks of human-to-human transmission via body fluids or droplets. Eliminating or minimising contact with rodents is the best way to prevent infection.
Hantaviruses are rodent-borne viruses can be transmitted to humans by contact with faeces/urine from infected rodents or with dust containing infective particles. They may cause severe diseases. Eliminating contact with rodents is the best way to prevent infection.
