The word Hanta comes from the Hantan River region, which is linked to the origin of the name hantavirus. Hantaviruses are RNA viruses usually carried by rodents and may cause serious disease in some humans. In everyday language, they may be referred to as “Hanta virus.” These viruses are commonly spread into the environment through the urine, feces, or saliva of rodents such as mice and rats. When they cause disease in humans, they may affect the respiratory system or kidneys. Therefore, Hanta refers to a group of rodent-borne viral infections rather than a single simple illness.
