Which rodent is known for being a carrier of the hantavirus?

The correct answer is the house mouse, which is recognized as a significant carrier of hantavirus. This virus can cause severe respiratory illnesses in humans, notably hantavirus pulmonary syndrome. The house mouse is particularly relevant because it can adapt to various environments, often living in close proximity to humans and their dwellings, which increases the potential for virus transmission.

When considering the other options, while Norway rats, roof rats, and white-footed mice may carry various pathogens, they are not the primary carriers of hantavirus. The hantavirus is notably associated with specific strains found in the droppings and body fluids of the house mouse, making it crucial to acknowledge the specific role this rodent plays in the transmission of hantavirus to humans.
