Which two species are primarily associated with the transmission of Hantavirus and Lyme's disease?

The correct answer is linked to the distinct species known to be reservoirs for Hantavirus and Lyme disease. The deer mouse and the white-footed mouse are both recognized as significant carriers of these pathogens.

The deer mouse is specifically associated with Hantavirus, as it can carry the virus without showing symptoms, facilitating its transmission to humans through direct contact with rodent excreta, saliva, or urine. This species is commonly found in rural areas, increasing the risk for humans, particularly in environments where they may come into contact with rodents.

Similarly, the white-footed mouse is a primary host for the Lyme disease pathogen, Borrelia burgdorferi. This species plays a crucial role in the ecology of Lyme disease, as it is a reservoir for the ticks that transmit the disease. When ticks feed on infected white-footed mice, they can acquire the bacteria and later infect humans during subsequent feedings.

By selecting these two species, the connection to the diseases is clearly established, and their roles in the transmission cycle highlight their importance in public health and vector control efforts.
