How is Hantavirus primarily transmitted?

Hantavirus is primarily transmitted through inhalation of aerosolized particles from the urine, feces, or saliva of infected rodents, particularly deer mice. When these droplets become airborne, they can be inhaled by individuals, leading to infection. This mode of transmission is particularly concerning in enclosed spaces where rodent droppings may accumulate, as it poses a significant risk to people who may inadvertently breathe in these particles.

The other methods of transmission mentioned in the options are not considered primary routes for Hantavirus. For instance, while touching infected surfaces could theoretically lead to transmission, the primary concern is with inhaling aerosolized particles. Eating food contaminated with the virus is not a common route of transmission. Insect bites do not transmit Hantavirus, as it is not spread by vectors such as mosquitoes. Lastly, direct skin contact with infected animals does not facilitate the transmission of Hantavirus; the primary concern is the inhalation of particles originating from the rodent's waste. Thus, the focus on breathing aerosolized mouse urine as the main method of transmission underscores the importance of precautions in areas where rodent infestations may occur.
