Which statement is true about hantavirus transmission to humans?

• A. It can be transmitted by inhalation of aerosols from rodent droppings
• B. It is transmitted by mosquitoes
• C. It is transmitted by sunlight exposure
• D. It is transmitted by plants

Answer: (A)

Hantavirus transmission to humans mainly occurs when virus-laden aerosols from rodent urine, droppings, or saliva are inhaled. Disturbing rodent-infested areas—such as cleaning out a dusty shed or basement—can release fine particles into the air, and breathing these in can lead to infection. This inhalation of aerosols from rodent excreta is the reason the statement is true. It’s not spread by mosquitoes, sunlight, or plants, so those options don’t fit. To reduce risk, wet-clean dusty areas before cleaning, wear appropriate protection, and control rodent access and populations.
