Which rodent is considered the primary reservoir for hantavirus?

The deer mouse is recognized as the primary reservoir for hantavirus. This designation stems from various scientific studies which have shown that deer mice carry the virus and are capable of transmitting it to humans, particularly through contact with their droppings, urine, or saliva. Unlike other rodents, the deer mouse's behavior and habitat preferences align closely with areas inhabited by humans, such as rural and semi-rural settings, increasing the likelihood of human exposure.

The risk of hantavirus pulmonary syndrome, a severe respiratory illness, is largely associated with this species because it is the most common carrier of the virus in North America. Understanding the role of deer mice in the ecology of hantavirus is crucial for environmental health specialists and sanitarians when assessing risks in various environments and during outbreaks. The knowledge helps inform prevention strategies and public awareness efforts to minimize the likelihood of hantavirus transmission from these rodents to humans.
